设计模式——职责链（责任链）模式

类模板

#include <bits/stdc++.h>
using namespace std;
//多少变量就写多少个
template<typename T1, typename T2>
class Cat
{
public:
	Cat(){}
	Cat(T1 name, T2 age)
	{
		this->age = age;
		this->name = name;
	}
	void print()
	{
		cout << this->name << ' ' << this->age << endl;
	}
private:
	T1 name;
	T2 age;
};
//另一个类模版
template<typename T1, typename T2, typename T3>
class Human
{
public:
	Human(){}
	Human(T1 name,T2 sex, T3 age)
	{
		this->age = age;
		this->name = name;
		this->sex = sex;
	}
	void print()
	{
		cout << this->name << ' ' << this->sex << ' ' << this->age << endl;
	}
private:
	T1 name;
	T2 sex;
	T3 age;
};

int main()
{
	Cat<string, int> cat("狸花猫", 2);
	Cat<string, int> *p = new Cat<string, int>("布偶猫", 18);
	cat.print();
	p->print();
	Human<string, string, int> person("陈皓林", "男", 18);
	person.print();
	return 0;
}

函数模板

#include <bits/stdc++.h>
using namespace std;
//函数模板
template <class T>
T Max(T a, T b)
{
	return a > b ? a : b;
}

int main()
{
	//函数模板的调用
	//隐式调用
	cout << Max(100, 1) << endl;
	cout << Max(string("aaa"), string("zaa")) << endl;
	//显式调用，尖括号传类型
	cout << Max<float>(3.14, 1.14) << endl;
	return 0;
}
