Here, we are finding ASCII value of any input character. %c is the format specifier to take character as input. Here, when we use %d instead of %c for character variable then it will print integer ASCII value of character. #include<stdio.h> #include<conio.h> void main() { char character; clrscr(); printf("Enter any character : "); scanf("%c" , &character); printf("\n\nASCII value of %c = %d",character,character); getch(); } OutPut Enter any character : s ASCII value of s = 115
