Dodaj binarny za pomocą strun

#include <iostream>
#include <string>
using namespace std;

int DecToBin(int dec)
{
    long long bin = 0;
    int j,rem, i = 1;

    for(j=dec;j!=0;j)
    {
        rem = j % 2;
        j /= 2;
        bin += rem * i;
        i *= 10;
    }

    return bin;
}

int main()
