Examples of Hex to Octal in Different Programming Languages


Here is an example of how to convert hexadecimal to octal in Python:

def hex_to_octal(hex_num):
    dec_num = int(hex_num, 16)
    octal_num = oct(dec_num)
    return octal_num[2:]

## Example usage
hex_num = "499602d2"
octal_num = hex_to_octal(hex_num)


Here is an example of how to convert hexadecimal to octal in C:

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

int main()
    char hex_num[] = "499602d2";
    char *endptr;
    long dec_num = strtol(hex_num, &endptr, 16);
    char octal_num[23];
    itoa(dec_num, octal_num, 8);
    printf("%s", octal_num);
    return 0;


Here is an example of how to convert hexadecimal to octal in JavaScript:

function hexToOctal(hexNum) {
  let decNum = parseInt(hexNum, 16);
  let octalNum = decNum.toString(8);
  return octalNum;

// Example usage
let hexNum = "499602d2";
let octalNum = hexToOctal(hexNum);


Here is an example of how to convert hexadecimal to octal in Java:

public class HexToOctal {
    public static void main(String[] args) {

        long decNum = Long.parseLong(hexNum, 16);
        String octalNum = Long.toOctalString(decNum);


Here is an example of how to convert hexadecimal to octal in PHP:

$hex_num = "499602d2";
$dec_num = hexdec($hex_num);
$octal_num = decoct($dec_num);
echo $octal_num;
