Binary Conversion Code (C++)

1. Binary to Decimal

Well, we know Binary is the number system containing only two digits or bits 0 and 1 and Decimal contains 10 digits (0-9).

#include<iostream>
using namespace std;

int BinDec(int num){
    int bits = num;
    int rem;
    int result = 0;
    int pow = 1;

    while(bits > 0){
        rem = bits % 10;
        result += rem * pow;
        pow = pow * 2;
        bits = bits/10;
    }
    cout<<result;
}

int main(){
    BinDec(1011);
}

2. Decimal to Binary

#include<iostream>
using namespace std;


int DecBin(int num){
    int n = num;
    int rem;
    int result = 0;
    int pow = 1;

    while(n > 0){
        rem =  n % 2;
        result += rem * pow;
        n = n/2;
        pow = pow * 10;
    }

    cout<<result;
}

int main(){
    DecBin(5);
}
