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
