A small program that prints integers in binary

#include <iostream>
using namespace std;

	return ((1<<bit)&num)>0;
}

void printBin(unsigned int num) {
	int i;
	cout << num <<" in binary is: ";
	for(i=8; i>=0; i--) {

			cout << "1";
		else
			cout << "0";
	}
	cout << endl;
}

void main() {
	printBin(10);
	printBin('A');
	printBin('M');
	printBin('A');
	printBin('R');
