Core Algorithm

To convert an octal number to hex, you need to first convert the octal number to binary and then convert the binary number to hexadecimal. The formula for converting an octal number to binary is:

Octal Number = (2^2 _ a) + (2^1 _ b) + (2^0 * c)

Where a, b, and c represent the digits of the octal number. Once you have the binary number, you can then use the formula for converting binary to hexadecimal, which is as follows:

Binary Number = (2^3 _ a) + (2^2 _ b) + (2^1 _ c) + (2^0 _ d)

Where a, b, c, and d represent the digits of the binary number.

Example Codes for Octal to Hex Conversion

Python:

## Octal to Hex conversion in Python

octal_num = "1234567"

## Convert octal to binary
binary_num = bin(int(octal_num, 8))

## Convert binary to hexadecimal
hex_num = hex(int(binary_num, 2))

print(hex_num)

C:

// Octal to Hex conversion in C

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

int main()
{
    char octal_num[] = "1234567";
    char *endptr;

    // Convert octal to binary
    long int binary_num = strtol(octal_num, &endptr, 8);

    // Convert binary to hexadecimal
    char hex_num[20];
    sprintf(hex_num, "%lX", binary_num);

    printf("%s\n", hex_num);

    return 0;
}

JavaScript:

// Octal to Hex conversion in JavaScript

let octal_num = "1234567";

// Convert octal to binary
let binary_num = parseInt(octal_num, 8).toString(2);

// Convert binary to hexadecimal
let hex_num = parseInt(binary_num, 2).toString(16);

console.log(hex_num);

Java:

// Octal to Hex conversion in Java

public class OctalToHex {

    public static void main(String[] args) {
        String octal_num = "1234567";

        // Convert octal to binary
        int binary_num = Integer.parseInt(octal_num, 8);

        // Convert binary to hexadecimal
        String hex_num = Integer.toString(binary_num, 16);

        System.out.println(hex_num);
    }
}

PHP:

// Octal to Hex conversion in PHP

$octal_num = "1234567";

// Convert octal to binary
$binary_num = decbin(octdec($octal_num));

// Convert binary to hexadecimal
$hex_num = dechex(bindec($binary_num));

echo $hex_num;
