Print Alphabets From A to Z Using Loop

Display all alphabets

This program prints all alphabets from A to Z using a loop. In C, characters are internally stored as ASCII values, so we can loop through them numerically.

📊 ASCII Values

'A' = 65

'Z' = 90

'a' = 97

'z' = 122

C Program to Print A to Z

3int main() {
4    char ch;
5    
6    printf("Uppercase Letters:\n");
7    for (ch = 'A'; ch <= 'Z'; ch++) {
8        printf("%c ", ch);
9    }
10    
11    printf("\n\nLowercase Letters:\n");
12    for (ch = 'a'; ch <= 'z'; ch++) {
13        printf("%c ", ch);
14    }
15    
16    printf("\n");
17    return 0;
18}

Output

Uppercase Letters:

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

Lowercase Letters:

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
