Kotlin Program to Display Alphabets (A to Z) using loop

In this article, we will understand how to print alphabets from A to Z or a to z in Kotlin. This is accomplished using a simple for-loop.

Below is a demonstration of the same

Suppose our input is

A to Z

The desired output would be

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Algorithm

  • Step 1 ? Start

  • Step 2 ? Declare a character variable: input

  • Step 3 ? Run a while loop with condition input greater that or equal to Z and print all the values satisfying the condition.

  • Step 4 ? Display the result

  • Step 5 ? Stop

Example 1

Here, we have displayed alphabets using a while loop in Kotlin. First declare and set a char variable:

var input: Char
input = 'A'

Now, use the while loop to print all the alphabets from A to Z ?


while (input < = 'Z') {
   print("$input ")
   ++input
}

Let us now see the complete example


fun main() {
   var input: Char
   input = 'A'
   println("Displaying Alphabets from A to Z ")

   while (input <= 'Z') {
      print("$input ")
      ++input
   }
}

Output

Displaying Alphabets from A to Z
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Example 2

Here, we have displayed alphabets A - Z in Kotlin ?


fun main() {
   var input: Char
   
   input = 'A'
   printAlphabets(input)
}

fun printAlphabets(inputCharacter: Char) {
   var input = inputCharacter
   println("Displaying Alphabets from A to Z ")
   while (input <= 'Z') {
      print("$input ")
      ++input
   }
}

Output

Displaying Alphabets from A to Z
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
