C++ - Decimal to binary converting

Question

I wrote a \'simple\' (it took me 30 minutes) program that converts decimal number to binary. I am SURE that there\'s a lot simpler way so can you show me? Here\'s the code:<

Answer 1

#include "stdafx.h"
#include
#include
#include

using namespace std;

int main() {
    // Initialize Variables
    double x;
    int xOct;
    int xHex;

    //Initialize a variable that stores the order if the numbers in binary/sexagesimal base
    vector rem;

    //Get Demical value
    cout << "Number (demical base): ";
    cin >> x;

    //Set the variables
    xOct = x;
    xHex = x;

    //Get the binary value
    for (int i = 0; x >= 1; i++) {
        rem.push_back(abs(remainder(x, 2)));
        x = floor(x / 2);
    }

    //Print binary value
    cout << "Binary: ";
    int n = rem.size();
    while (n > 0) {
        n--;
        cout << rem[n];
    } cout << endl;

    //Print octal base
    cout << oct << "Octal: " << xOct << endl;

    //Print hexademical base
    cout << hex << "Hexademical: " << xHex << endl;

    system("pause");
    return 0;
}
