ASCII Character codes

ASCII stands for American Standard Code for Information Interchange. It is a set of integer values that represents different printable and non-printable characters.

In C programming characters are stored as an integer value (ASCII value). Hence, you can perform all basic arithmetic operations on character.

Logic to print ASCII value of all characters

Step by step descriptive logic to print ASCII value of all characters.

  1. Declare an integer variable i as loop counter.
  2. Run a loop from 0 to 255, increment by 1 in each iteration. The loop structure must look like for(i=0; i<=255; i++).

    Why iterate from 0 to 255? Because total number of ASCII characters is 256 (non-printable + printable + extended ASCII) and values are in between 0 to 255.

  3. Inside the loop print character representation of the given integer.

Program to print ASCII values

/**
 * C program to print ASCII values of all characters.
 */

#include <stdio.h>

int main()
{
    int i;

    /* Print ASCII values from 0 to 255 */
    for(i=0; i<=255; i++) 
    {
        printf("ASCII value of character %c = %d\n", i, i);
    }

    return 0;
}

In the above program I have used %c format specifier with an integer type. Performing this will print ASCII character represented by the integer i.

Note: You can use any format specifier with any type if it supports the operation.
