What Is ASCII Code In C Language?

ASCII stands for the American Standard Code for information interchange. It is a character encoding system used for electronics communication devices. In Electronics communication devices each characters represented by number from 0 to 127 that is stored as binary format (bits) in memory. ASCII use 7 bits for store a char value. A character variable does not contain character, it contain numbers from 0 to 127. when we assign a character in a variable it store its ASCII code. we can print character as number using %d format specifier. For example, if we print 'A' with %d output will be 65.

In This Examples we are printing A to Z using ASCII code.

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char const *argv[])
{
    char x = 65; // char x = 'A'  ASCII value of 'A'
    for (x; x < 65 + 26; x++)
    {
        printf(" %c", x);
    }
    return 0;
}
