C Program for ASCII to Character Conversion

Ascii to character conversion

ASCII is the abbreviation of American Standard Code for Information Interchange. It is a character encoding standard for electronic communication. ASCII encodes 128 specified characters into seven-bit integers. It contains the numbers from 0 - 9, the upper and lower case English letters from A to Z and some special characters.

  The following C program converts a given ASCII value to its equivalent character. The algorithm, time complexity and pseudocode of the program have also been added.

1. Algorithm for ASCII to Character Conversion

1. Take an ASCII value (Integer (0 - 127)) as input.

2. Do cast the integer to the corresponding character.

3. Return the result

2. Pseudocode for ASCII to Character Conversion

Input : An integer (0 - 127) $i$

Output : A character $c$

1. Procedure toCharacter($i$):

2. Return (Char($i$))

3. End Procedure

3. Time complexity for ASCII to Character Conversion

Time Complexity: O(1)

4. C Program & output for ASCII to Character Conversion

 C program for ASCII to character conversion

#include <stdio.h>

int main() {
    // declare variables
    char x;
    int v = 80;

    //convert and store the corresponding character
    x = (char) v;

    // display result
    printf("Equivalent character of ASCII value %d is = %c", v, x);

    return 0;


Equivalent character of ASCII value 80 is = P
