What is ASCII?

ASCII stands for American Standard Code for Information Interchange.

It is a character encoding standard that represents text characters (like letters, digits, and symbols) using integer values.

In C programming:

• Every character has an ASCII value.
• For example, 'A' is 65, 'a' is 97, '0' is 48, etc.
• You can use characters as integers in C because characters are stored as ASCII codes.

ASCII Examples in C

Example 1: Print ASCII value of a character

#include <stdio.h>

int main() {
    char ch = 'A';
    printf("ASCII value of %c is %d\n", ch, ch);
    return 0;
}

Output:

ASCII value of A is 65

Example 2: Convert lowercase to uppercase

#include <stdio.h>

int main() {
    char lower = 'b';
    char upper = lower - 32;
    printf("Uppercase of %c is %c\n", lower, upper);
    return 0;
}
