Suggested January 2024 Swift Program To Print Half Diamond Star Pattern

This tutorial will discuss how to write swift program to print half diamond star pattern.

Star pattern is a sequence of “*” which is used to develop different patterns or shapes like pyramid, rectangle, cross, etc. These star patterns are generally used to understand or practice the program flow controls, also they are good for logical thinking.

Create a half diamond star pattern, we can use any of the following methods −

Using nested for loop

Using init() Function

Using stride Function

Below is a demonstration of the same −

Input

Suppose our given input is −

Num = 7

Output

The desired output would be −

* ** *** **** ***** ****** ******* ****** ***** **** *** ** * Method 1 – Using Nested For Loop

We can create a half diamond star pattern or any other pattern using nested for loops. Here each for loop handle different tasks such as outermost for loop is used for new rows, and nested for loop is used for “*”.

Algorithm

Following is the algorithm −

Step 1 − Declare variable to store the height of the half diamond star pattern

For upper half diamond star pattern −

Step 2 − Run an outer for loop from 1 to num. This loop handle the total number of rows are going to print and each row is start with new line.

Step 3 − Run nested for loop from 1 to i. This loop is used print upper half diamond star pattern.

For lower half diamond star pattern −

Step 4 − Again run an outer for loop from 1 to num-1. This loop handle the total number of rows are going to print and each row is start with new line.

Step 5 − Run another nested for loop from 1 to num-j. This loop is used print lower half diamond star pattern.

Example

The following program shows how to print half diamond star pattern using nested for loop.

import

Glibc

let

num

=

9

for

i

in

1.

.

.

num

{

for

_

in

1.

.

.

i

{

print

(

“*”

,

terminator

:

“”

)

}

print

(

“”

)

}

for

j

in

1.

.

.

num

1

{

for

_

in

1.

.

.

num

j

{

print

(

“*”

,

terminator

:

“”

)

}

print

(

“”

)

}

Output * ** *** **** ***** ****** ******* ******** ********* ******** ******* ****** ***** **** *** ** *

Method 2 – Using init() Function

Swift provide an in-built function named String.init(). Using this function, we can able to create any pattern. String.init() function create a string in which the given character is repeated the specified number of times.

Syntax

Following is the syntax −

String.init(repeating:Character, count: Int)

Here, repeating represent the character which this method repeats and count represent the total number of time the given character repeat in the resultant string.

Algorithm

Following is the algorithm −

Step 1 − Declare variable to store the length of the half diamond star pattern.

Step 2 − Run a for loop from 1 to num. This loop prints the upper hand diamond star pattern using init() function −

for x in 1...num{ print(String.init(repeating: "*", count: x)) }

Here, in each iteration init() function print “*” according to the value of x. For example if x = 2, then init() prints “**”.

Step 3 − Run another for loop from 1 to num-1. This loop prints the lower half diamond star pattern using init() function −

for x in 1...num-1{ print(String.init(repeating: "*", count: num-x)) } Example

The following program shows how to print half diamond star pattern using string.init() function.

import

Glibc

let

num

=

9

for

x

in

1.

.

.

num

{

print

(

String

.

init

(

repeating

:

“*”

,

count

:

x

)

)

}

for

x

in

1.

.

.

num

1

{

print

(

String

.

init

(

repeating

:

“*”

,

count

:

num

x

)

)

}

Output * ** *** **** ***** ****** ******* ******** ********* ******** ******* ****** ***** **** *** ** * Method 3 – Using Stride Function

Swift provide an in-built function named stride(). The stride() function is used to move from one value to another with increment or decrement. Or we can say stride() function return a sequence from the starting value but not include end value and each value in the given sequence is steps by the given amount.

Syntax

Following is the syntax −

stride(from:startValue, to: endValue, by:count)

Here,

from − Represent the starting value to used for the given sequence.

to − Represent the end value to limit the given sequence

by − Represent the amount to step by with each iteration, here positive value represent upward iteration or increment and negative value represent the downward iteration or decrement.

Example

The following program shows how to print half diamond star pattern using stride() function.

import

Glibc

let

num

=

9

for

i

in

1.

.

.

num

{

for

_

in

1.

.

.

i

{

print

(

“*”

,

terminator

:

“”

)

}

print

(

” “

)

}

for

j

in

1.

.

.

num

1

{

for

_

in

stride

(

from

:

num

,

to

:

j

,

by

:

1

)

{

print

(

“*”

,

terminator

:

“”

)

}

print

(

” “

)

}

Output * ** *** **** ***** ****** ******* ******** ********* ******** ******* ****** ***** **** *** ** *

## Golang Program To Print Right Triangle Star Pattern

In this tutorial we will write a Go-lang code to print a right Triangle star pattern. We will depict how you can print the star pattern in go language.

* * * * * * * * * * How to print a star pattern?

A right triangle star pattern is shown above, and in that pattern, you can see that stars are increasing with the increase in the number of rows. The pattern goes like this 1 star in first row, 2 stars in second row, and goes on.

For loop statement(s); } Example1: Golang Program To print Right Angled Star Pattern Algorithm

Step 1 − Import the package fmt.

Step 2 − Start function main().

Step 3 − Declare and initialize the integer variables.

Step 4 − Use the first for loop to iterate through the row from 1 to “number of rows”.

Step 5 − Use the second for loop to iterate through columns from 1 to i, to print a star pattern.

Step 5 − After printing all columns of a row move to next line i.e., print new line.

Example

The golang program to print a right triangle star pattern is compiled and executed in the following code −

package

main

import

“fmt”

func

main

(

)

{

var

i

,

j

,

row

int

row

=

5

fmt

.

Println

(

“nRight Angled Star Pattern”

)

for

i

=

1

;

i

<=

row

;

i

++

{

for

j

=

1

;

j

<=

i

;

j

++

{

fmt

.

Print

(

“* “

)

}

fmt

.

Println

(

)

}

}

Output Right Angled Star Pattern * * * * * * * * * * * * * * * Description of the Code

In the above code first we import the main package and the fmt package the fmt package allows us to print anything on the screen.

Then start the main() function.

Declare and initialize i, j and row variables of data type int.

Let us assign 5 to the number of rows i.e for the sake of this example let us print a star pattern with 5 number of rows.

i and j are used to iterate over the for loop. They will select the respective rows and columns for printing the * character.

To print this kind of pattern we need to use a for loop within another for loop. The first for loop is used to select the row, it iterates from 1 to the number that the rows contained by row variable.

The second for loop starts from j = 1 to the value of current row. The value of current row is the value of i variable.

Use the fmt.Print() function to print the * character inside second for loop.

For the first row second for loop will not start and one * character will get printed.

For the second row i = 2 and in this case the second for loop will iterate from j = 1 to j = 2 in this manner in second row two * characters will get printed.

In this manner the right triangle pattern will get printed.

Example 2: Golang Program to Print Right Triangle Star pattern using Recursion Algorithm

Step 1 − Import the package fmt

Step 2 − Define a printSpace() function.

Step 3 − Define a printRow() function to print rows of star pattern recursively.

Step 4 − Define a Star() function to print new line recursively.

Step 5 − Declare and initialize the integer variables.

Step 6 − Call the printRow() function.

Example

package

main

import

“fmt”

func

printRow

(

number

int

)

{

printRow

(

number

1

)

fmt

.

Printf

(

“*”

)

}

}

func

star

(

number

int

)

{

star

(

number

1

)

}

printRow

(

number

)

fmt

.

Println

(

)

}

func

main

(

)

{

var

row

int

=

7

star

(

row

)

}

Output * ** *** **** ***** ****** ******* Description of the Code

In the above code first we import the main package and the fmt package the fmt package allows us to print anything on the screen.

Create two functions naming printRow() and star().

printRow() function will print the star character in the selected number of rows.

Star() function will print new line and will call printRow() function to print * in the selected row.

Then start the main() function.

Initialize row variables of data type int and store number of rows that you want to print in star pattern to it.

Call the star() function and pass row variable as argument to it.

Conclusion

We have successfully compiled and executed a go language program to print a right-angled star pattern.

To print this star pattern, we have used recursion here in which we are calling two functions recursively.

## Swift Program To Check Armstrong Number

The sum of nth power of individual digit of a number is equal to the number itself, then such type of number is known as Armstrong number.

Suppose we have a number 407 so here n = 3

153 = 13 + 53 + 33

153 = 1 + 125 + 27

153 = 153

Hence 153 is Armstrong number

Suppose we have another number 8973, so here n = 4

8973 = 84 + 94 + 74 + 34

8973 = 4096 + 6561 + 2401 + 27

8973 = 13085

Hence 8973 is not an Armstrong number.

Below is a demonstration of the same −

Input 1

Suppose our given input is −

Number = 407

Output

The desired output would be −

YES! 407 is an Armstrong Numbers

Input 2

Suppose our given input is −

Number = 12489

Output

The desired output would be −

NO! 12489 is not an Armstrong Numbers Algorithm

Following is the algorithm −

Step 1 − Declare two variables to store the lower and upper limit.

Step 2 − Run a for loop from lower limit to upper limit to iterate through each element.

Step 3 − Declare another variable to store the sum.

Step 4 − Declare on more variable to store the count of the total number of digits present in the given number.

Step 5 − Count the total number of digits present in the given number −

while(armNum != 0){ armNum = armNum/10 count = count + 1 }

Step 6 − Calculate the sum of power of individual digit the given number

let rem = armNum % 10 sum = sum + (rem * rem * rem) armNum = armNum/10

Step 7 − Compare the sum with the number itself. If both sum and number are equal, then the number is the Armstrong number. Otherwise not.

Step 8 − Print the output.

Check 3-digit Armstrong Numbers Example

The following program shows how to check an Armstrong number.

import

Glibc

var

myNumber

=

407

var

sum

=

0

var

n

=

myNumber

while

(

n

!=

0

)

{

let

rem

=

n

%

10

sum

=

sum

+

(

rem

*

rem

*

rem

)

n

=

n

/

10

}

if

(

sum

==

myNumber

)

{

print

(

“YES! (myNumber) is an Armstrong number”

)

}

else

{

print

(

“NO! (myNumber) is not an Armstrong number”

)

}

Output YES! 407 is an Armstrong number

Here, in the above code, we have a number = 407. Now we find the sum of 3rd power of the individual digit of the number. After calculating the sum now we find compare the sum is equal to the given number. If the sum is equal to the number, then the number is Armstrong number. Otherwise not. So the working of the above code is −

myNumber = 407 Sum = 0 1st iteration: while (407 != 0){ let rem = 407 % 10 = 7 sum = sum + (rem * rem * rem) = 0 + (7 * 7 * 7) = 343 n = 407/10 = 40 } 2nd iteration: while (40 != 0){ let rem = 40 % 10 = 0 sum = sum + (rem * rem * rem) = 343 + (0* 0 * 0) = 343 n = 40/10 = 4 } 3rd iteration: while (4 != 0){ let rem = 4 % 10 = 4 sum = sum + (rem * rem * rem) = 343 + (4* 4 * 4) = 343 + 64 = 407 n = 4/10 = 0 } Sum = 407 if (407 == 407) print("YES! (myNumber) is an Armstrong number") }

Hence the output is “YES! 407 is an Armstrong number” because 407 is as Armstrong number.

Check n-digit Armstrong Numbers Example

The following program shows how to check an Armstrong number.

import

Glibc

var

num

=

40689

print

(

“Number:”

,

num

)

var

sum

=

0

var

armNum

=

num

var

count

=

0

while

(

armNum

!=

0

)

{

armNum

=

armNum

/

10

count

=

count

+

1

}

armNum

=

num

while

(

armNum

!=

0

)

{

let

rem

=

armNum

%

10

sum

=

sum

+

Int

(

pow

(

Double

(

rem

)

,

Double

(

count

)

)

)

armNum

=

armNum

/

10

}

if

(

sum

==

num

)

{

print

(

“Yes the number is an Armstrong number”

)

}

else

{

print

(

“No the number is not an Armstrong number”

)

}

Output Number: 40689 No the number is not an Armstrong number

Here, in the above code, we have a number = 40689. Now we check the number is an Armstrong number or not. So, to find Armstrong number, we first calculate the total number digits present in the number. After that we find the sum of nth power of the individual digit of the number. Now after calculating the sum we check the sum is equal to the given number or not by comparing each other. If the sum is equal to the number, then the number is Armstrong number and print the output. So number = 40689 is not an Armstrong number.

## How To Print From Your Chromebook

In Windows, you can install the driver for your printer and print document on your PC. What about Chromebook? With a lack of dedicated software for printing, it may seem confusing at first glance. Fortunately, it’s not confusing at all, and in just a few easy steps, Chromebook users will be on their way to printing documents, photos and more. Keep reading for all of the steps you need to know to print from your Chromebook.

Contrary to popular opinion, Chrome OS does have native printing built in, so adding a printer doesn’t require hacker-level computer knowledge. To add a local printer, follow the steps below.

It is easy to set up a printer on ChromeOS. The act of printing is even easier. The first and most critical step is to find a page you want to print.

At this point, using Cloud Print, your printing should start just as it would from any computer.

Using Android Apps

A lesser-used but still viable option for adding printers to a Chromebook is Android apps. With most recent Chromebooks enabling Android app functionality, downloading printer apps from the Play Store is a smart workaround. Apps like Canon, HP, Epson, Samsung, Brother and more are all available in the Play Store. After downloading the app, most will allow you to set up and sync the printer directly from the app itself. While not the most common way, these apps are one of the quickest ways to print directly from a Chromebook.

Wrapping Up

As you can see, it is easy to print from Chromebook. There is no need to install abdriver like in Windows. There are also plenty of things you can do on a Chromebook, like playing games, installing Firefox, or managing zip files.

## How To Print Screen Without Printscreen Button

In this post, we show you how to take a screenshot without the Print Screen button. You can print screen without PrintScreen button by using any one of these alternative methods. There could be times when the PrintScreen button might not be working, and as a result, you would not be able to capture screenshots. In such situations, you can follow these suggestions to print the screen without the PrintScreen button on your keyboard. Here are multiple methods enlisted so that you can follow one of them as per your requirements.

When you press the PrintScreen button, your computer captures your screen. Although it doesn’t save it automatically, you can open any image editing app, including Paint, Paint 3D, etc., to paste the screenshot. However, if the PrintScreen button is not working or freezing frequently, you won’t be able to capture screenshots. In such a moment, you can go through these solutions.

How to print screen without PrintScreen button

To take a screenshot without the Print Screen button on your Windows computer, follow these suggestions:

Use On-Screen Keyboard

Use Win+Shift+S

Use Snipping Tool

Remap PrintScreen key

Use third-party app

1] Use On-Screen Keyboard

It is the handiest solution, and it works smoothly on Windows 11 as well as Windows 10 computers. Your computer comes with an in-built On-Screen Keyboard that helps you type using your mouse. It is a helping hand when your physical keyboard is not working properly.

To use On-Screen Keyboard to capture screenshots in Windows 11/10, follow these steps:

Search for on screen keyboard in the Taskbar search box.

Use your mouse to open Paint and save the screenshot.

For your information, you can edit the image as usual and save it almost anywhere.

2] Use Win+Shift+S

Win+Shift+S is the keyboard shortcut to use the Snipping Tool’s direct option to capture a screenshot. You can use this screenshot to set almost any shape to capture your screen. From choosing the rectangle, specific window, or entire screen, you can select anything and capture it as a screenshot.

To use this method, press Win+Shift+S together. Then, you need to use your mouse to select the area.

However, if you want to capture a window or rectangle screenshot, you can select such an option from the top menu bar.

3] Use Snipping Tool

Snipping Tool has been there in Windows operating system for a long time. You can use Snipping Tool to capture screenshots easily on your Windows PC. It offers several modes, including Rectangle mode, Window mode, Full-screen mode, and Free-form mode.

On the other hand, you can delay the capture as well. For your information, you can enable Snipping Tool using the aforementioned keyboard shortcut as well.

However, you can also open the original Snipping Tool window to find all the above-mentioned options. In that case, you can customize the capture as per your requirements.

4] Remap PrintScreen key

If the PrintScreen key is not working, you can remap the function to another unused key. Although Windows 11/10 doesn’t have an in-built option to remap a key, you can use PowerToys to get the job done.

PowerToys is one of the best apps to enrich or enhance the functionalities of your Windows computers. Whether you need to improve the performance of your mouse or keyboard or manage shortcuts, you can do almost anything with the help of this app.

If you already have it, you can open the app and go to the Keyboard Manager. However, if you do not have the PowerToys installed on your computer, you can follow this guide to download and install PowerToys on Windows 11.

5] Use third-party app

## How To Print Double Sided On Mac

Double-sided or duplex printing is a good choice if you’re environmentally conscious or want to economize on paper. Plus, knowing how to print double-sided on your Mac can also elevate the presentation of your documents.

Many inkjet and laser printers have the duplex printing function built in, but the way you access it may differ depending on where you’re printing from. If you’re using a Mac, you can print double-sided whether or not the printer has this feature.

We’ll walk you through the different methods you can use to print double-sided on Mac whether you’re using a program or browsing online.

How to Print Double-Sided on Mac from an App

You can print double-sided on your Mac when using an application such as Notes, or Microsoft Office apps.

Microsoft Office apps output their own printing dialog window, which makes the double-sided printing process simpler, with fewer steps. However, this dialog window may confuse you at first if you haven’t printed on Mac before.

How to Print Double-Sided on Mac Using Microsoft Applications

For this guide, we’ll show you how to print double-sided using Microsoft Word. The steps below are the same for other Microsoft apps including Excel and PowerPoint.

In the Two-Sided submenu, you’ll find the Long-Edge binding and Short-Edge binding options. Select Long-Edge binding.

Note: Long-edge binding allows you to print double-sided sheets and its margins are adjusted for binding on the left. This way, you can turn pages sideways as you would with a long-form document or book. On the other hand, short-edge binding margins adjust for binding at the top, and pages are printed such that you can flip them over vertically as you would with a calendar or notepad.

Select Print.

Note: Most Mac apps call out a somewhat standard printing dialog window compared to Microsoft apps, which have a rather custom printing process. To see the difference, here’s how to print a PDF document using the double-sided function on Mac.

How to Print Double-Sided on Mac from Google Docs

If you’re working on a document in Google Docs (or any other web app or web page), you can still print double-sided from there.

To do this, use the ⌘ + P keyboard shortcut, or go to File in the Google Docs menu and select Print.

Next, check the Two-Sided box and then select Print.

How to Print Double-Sided on Mac Using a Non-Duplex Printer

If your printer doesn’t support duplex printing, you can still print double-sided in a few steps.

The first step is to check whether the duplexing feature is enabled on your printer.

Select your printer from the list and then select Options & Supplies.

Set the value to Odd Only in the Pages to Print section.

Select Print to select Odd Only to print only odd-numbered pages.

Next, flip your printed pages over and put them back into your printer. Open the Print menu again, and select Even Only in the Pages to Print section.

Select Print.

Note: Using a non-duplex printer to print double-sided can involve some trial and error to get it done right. If you have a large document, try it with two or four pages before printing the entire document. Duplex printing may not work well with older laser printers where heat is involved, because you can’t safely put your paper through twice.

Save Paper and Money

Whether your printer has a duplex feature or not, you can easily print double-sided on Mac. It will help you save paper and money, and you don’t have to worry about running out of paper all the time.
