class help

I am trying to print out the result of binary addition, but when I run the program nothing prints out. I have been stuck at this point for quite some time and would really appreciate any help.

#include "binNum.h"
#include "misc_ops.h"

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

int main()
{
	int i = 0;
	binNum num;
	num.numbers();
	num.addition(i);

	//cout << i << endl;


	  	//keeps the output window open
	cout << "Press enter to continue \n"; 
	cin.sync();
	cin.ignore();
	char ch = getchar();

  return 0;
}
