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
