栈实现队列

错误答案

#include<stdio.h>
#include<stack>
using namespace std;

class MyQueue(){
	stack<int> tem_s;
	void push(int x){
		while(!data.empty()){
			tem_s.push(data.top());
			data.pop();
		}
		tem_s.push(x);
		while(!tem_s.empty()){
			data.push(tem_s.top());
			tem_s.pop();
		}
	}
	int pop(){
		data.pop();
	}
	int top(){
		return data.top();
	}
	bool empty(){
		return data.empty();
	}
}

int main(){
	
	MyQueue q;
	q.push(1);
	q.push(2);
	q.push(3);
	q.push(4);
	printf("%d\n",q.top());
	q.pop();
	printf("%d\n",q.top());
	
	return 0;
}
