#include <stdio.h>int main(){ char ch; printf("Enter any character:"); /* Reads the entered character and stores it * into the char variable ch */ scanf("%c", &ch); /* Using the format specifiers we can get the ASCII code * of a character. When we use %d format specifier for a * char variable then it displays the ASCII value of a char */ printf("ASCII value of character %c is: %d", ch, ch); return 0;}输出:
