Example

#include <stdio.h>
int main()
{
    char c;
    printf("Enter a character: ");

    // Read user input
    scanf("%c", &c);  

    // %d displays the integer value
    // %c displays the corresponding character
    printf("The ASCII value of %c is %d", c, c);
    return 0;
}

Running Result:
