#include<stdio.h>;
void main()
{
    char test;
    printf("Enter a character :");
    scanf("%c",&test);
    printf("The ASCII value of %c is = %d :",test,test);
}

OUTPUT : 1.

Enter a character :x
The ASCII value of x is = 120 :

2.

Enter a character :%
The ASCII value of % is = 37 :
In this code we take a char and print that using %d,
it will not change value of test.
