stack 的入门

#include "iostream"
#include "stack"

using namespace std;

void main12()
{
stack <int> s; //定义一个栈

for (int i = 0; i < 5; i++)
{
//往栈里面赋值
s.push(i);
}

while (!s.empty())
{
int tmp = s.top(); //获取栈顶的元素
s.pop(); //弹出栈顶的元素
cout << tmp << endl;
}
system("pause");
}

struct Teacher
{
int age;
char name[10];
};

void printf_stack(stack<Teacher> &s)
{
while (!s.empty())
{
cout << s.top().age << endl;
s.pop();
}
}

void main()
{
//定义一个栈
Teacher t1, t2, t3;
t1.age = 11;
t2.age = 22;
t3.age = 33;

stack<Teacher> s;

s.push(t1);
s.push(t2);
s.push(t3);

printf_stack(s);

system("pause");
}
