十进制转二进制输出，算法很简单，可以作为入门练习：

#include "pch.h"
#include<iostream>
using namespace std;
int BinaryFunc(int ten) {
	int yushu = 0;
	int i = 0;
	int result = 0;
	for (; ten >= 2;) {
		yushu = ten % 2;
		ten /= 2;
		result += (yushu * pow(10,i));
		i++;
	}
	result += (ten* pow(10,i));
	return result;
}
void main() {
	int ten = 0;
	cin >> ten ;
	cout << BinaryFunc(ten) << endl;

}
