“自适应容器：栈和队列”的实例应用

题目一： 

#include <iostream>
#include <queue>
#include <functional>
using namespace std;

enum Sex
{
	Women = 1, Men = 0,
};

struct Person 
{
	int TrueAge;
	char TrueSex;
	Sex sex;

	Person(int TrueAge, char TrueSex)
	{
		this->TrueAge = TrueAge;
		this->TrueSex = TrueSex;
		sex = TrueSex == 'f' ? Women : Men;
	}
	bool operator < (const Person& person1) const // 此时的this指针为指向常量的指针常量(const Person const*)
	{
		int Age1 = this->TrueAge >= 60 ? this->TrueAge : 20;
		int Age2 = person1.TrueAge >= 60 ? person1.TrueAge : 20;
// 我一般排列数组内的元素喜欢用权重，把各部分给予相应的权重，最终以求和后的数值来排序
		return (Age1 + this->sex) < (person1.sex + Age2);
	}
	friend ostream& operator << (ostream& Output, const Person& Person1);
};
ostream& operator << (ostream& Output, const Person& Person1)
{
	Output << Person1.TrueAge << " " << Person1.TrueSex; // 这里千万不要用endl清空缓存区
	return Output;
}

int main()
{
	Person Person1(63, 'm'), Person2(32, 'f'), Person3(82, 'f');
	priority_queue<Person, vector<Person>, less<Person>> PriorQueueArray;
	PriorQueueArray.push(Person1);
	PriorQueueArray.push(Person2);
	PriorQueueArray.push(Person3);

	while (!PriorQueueArray.empty())
	{
		cout << PriorQueueArray.top() << endl;
		PriorQueueArray.pop();
	}
}

 题目二：

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

int main()
{
	stack<string, vector<string>> StackArray;
	StackArray.push("张三");
	StackArray.push("李四");
	StackArray.push("王五");
	while (!StackArray.empty())
	{
		cout << StackArray.top() << endl;
		StackArray.pop();
	}
}
