Program to Print Alphabets From A to Z Using Loop

Last Updated : 11 Jul, 2025

Our task is to print the alphabets from A to Z using loops. There are various methods to print alphabets from (A to Z) or (a to z).

  • Using ASCII values
  • Using character variables.

In this article we will mainly focus on the following programs and their logic:

  • Using for loop
  • Using the while loop
  • Using a do-while loop

 Program to display alphabets using ASCII values


Output
Alphabets from (A-Z) are:
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 
Alphabets from (a-z) are:
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

Program to print (A to Z) and (a to z) using for loop

In the below program,

  • For loop is used to print the alphabets from A to Z. A loop variable is taken to do this of type 'char'. 
  • The loop variable 'i' is initialized with the first alphabet 'A' and incremented by 1 on every iteration.
  • In the loop, the character 'i' is printed as the alphabet.

Program:


Output
The Alphabets from A to Z are: 
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 
The Alphabets from a to z are: 
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

Program to print (A to Z) and (a to z) using the while loop

In the below program,

  • While loop is used to print the alphabets from A to Z. A loop variable is taken to display of type 'char'. 
  • The loop variable 'i' is initialized with the first alphabet 'A' and incremented by 1 on every iteration.
  • In the loop, the character 'i' is printed as the alphabet.

Output
The Alphabets from A to Z are: 
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 
The Alphabets from a to z are: 
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

Program to print (A to Z) and (a to z) using a do-while loop

In the below program,

  • The do-while loop is used to print the alphabets from A to Z. A loop variable is taken to display of type 'char'. 
  • The loop variable 'i' is initialized with the first alphabet 'A' and incremented by 1 on every iteration.
  • In the loop, the character 'i' is printed as the alphabet.

Output
The Alphabets from A to Z are: 
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 
The Alphabets from a to z are: 
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
