Write a C program to display Alphabets (a - z) and (A - Z) using loop

Loops can be used to perform repetitive tasks efficiently and one such task is displaying the entire range of alphabets. In this article, we will explore how to write a C program that utilizes loops to display both lowercase (a - z) and uppercase (A - Z) alphabets.

C program to print Lower Case alphabets:

Consider the below code example where we will print the lowercase alphabets (a-z) using a loop:

#include <stdio.h>
int main()
{
    char c;
 
    for(c = 'a'; c <= 'z'; ++c)
      printf("%c ", c);
    
    return 0;
}

Output:

C program to print Upper Case alphabets:

Consider the below example code where we will print the Upper case alphabets (A-Z) using a loop:

#include <stdio.h>
int main()
{
    char c;
 
    for(c = 'a'; c <= 'z'; ++c)
      printf("%c ", c);
    
    return 0;
}

Output:

Conclusion

You have learned how loops can be used to automate the generation and printing of alphabets in C.
