C Program to find ASCII value of a character

We will learn here how to write a C program to find ASCII value of a character. When we assign a character to a character variable in C . It does not holds the character, it holds that character’s ASCII value. For example char cv = B . In this example , variable cv will hold ASCII value of B i.e. 66 . If we print cv it will output 66 rather than B .

Let us see with a practical program how to write a C program to find ASCII value of a character.

#include <stdio.h>
int main() {  
    
    char cv;
    
    printf("Enter a character: ");
    
    scanf("%c", &cv);  
    
    // %d displays  integer value of a character
    
    // %c displays the  character itself
    
    printf("ASCII value of %c = %d", cv, cv);
    
    return 0;
}

Output :

Enter a character: B
ASCII value of B = 66

First we declare character variable cv and asked user to input a character and store user input in variable cv. %d is used to display integer value of character and %c is used to display the character itself.
