Unleashing the Power of C++: Binary and Octal Conversions Made Easy

Unlocking the Secrets of Number Systems

Understanding different number systems is crucial in programming. In this article, we’ll explore the world of binary and octal conversions using C++. To follow along, you’ll need to have a solid grasp of C++ functions, user-defined function types, if-else statements, and while loops.

Converting Binary to Octal: A Step-by-Step Guide

Imagine you’re tasked with converting a binary number to octal. How would you approach this problem? One effective solution is to first convert the binary number to decimal, and then convert the decimal number to octal. Let’s take a closer look at an example program that demonstrates this process:

#include <iostream>
using namespace std;

string convertBinaryToOctal(string binary) {
    int decimal = 0;
    int base = 1;

    for (int i = binary.length() - 1; i >= 0; i--) {
        decimal += (binary[i] - '0') * base;
        base *= 2;
    }

    string octal = "";
    while (decimal!= 0) {
        octal = to_string(decimal % 8) + octal;
        decimal /= 8;
    }

    return octal;
}

int main() {
    string binary;
    cout << "Enter a binary number: ";
    cin >> binary;

    string octal = convertBinaryToOctal(binary);
    cout << "The octal equivalent is: " << octal << endl;

    return 0;
}

The output? A beautifully converted octal number!

The Reverse Process: Converting Octal to Binary

But what if you need to convert an octal number to binary? No problem! The process is similar, but with a twist. First, the octal number is converted to decimal, and then the decimal number is converted to binary. Let’s examine an example program that showcases this process:

#include <iostream>
using namespace std;

string convertOctalToBinary(string octal) {
    int decimal = 0;
    int base = 1;

    for (int i = octal.length() - 1; i >= 0; i--) {
        decimal += (octal[i] - '0') * base;
        base *= 8;
    }

    string binary = "";
    while (decimal!= 0) {
        binary = to_string(decimal % 2) + binary;
        decimal /= 2;
    }

    return binary;
}

int main() {
    string octal;
    cout << "Enter an octal number: ";
    cin >> octal;

    string binary = convertOctalToBinary(octal);
    cout << "The binary equivalent is: " << binary << endl;

    return 0;
}

The output? A perfectly converted binary number!
