黑马程序员C++提高5——stack容器【栈】

#include<stack>
#include<iostream>
using namespace std;

void test01() {
    
    

	//初始化
	stack<int> s1;		//默认构造
	stack<int> s2(s1);	//拷贝构造

	//存取操作
	s1.push(10);
	s1.push(20);
	s1.push(30);
	s1.push(40);
	s1.push(100);
	cout << "此时的栈顶元素top：" << s1.top() << endl;
	s1.pop();
	cout << "此时的栈顶元素top：" << s1.top() << endl;
	
	cout << "s2.size: " << s2.size() << endl;
	//赋值
	s2 = s1;
	cout << "s2.size: " << s2.size() << endl;

	//打印栈容器数据
	while (!s2.empty()) {
    
    
		cout << s2.top() << " ";
		s2.pop();
	}
}

int main() {
    
    
	test01();
	
	cout << endl << endl;
	return 0;
