C++ 模板 传入值的三种方式

#include <string>
//类模板
template<class NameType, class AgeType = int> 
class Person
{
public:
	Person(NameType name, AgeType age)
	{
		this->mName = name;
		this->mAge = age;
	}
	void showPerson()
	{
		cout << "name: " << this->mName << " age: " << this->mAge << endl;
	}
public:
	NameType mName;
	AgeType mAge;
};

//1、指定传入的类型
void printPerson1(Person<string, int> &p) 
{
	p.showPerson();
}
void test01()
{
	Person <string, int >p("孙悟空", 100);
	printPerson1(p);
}

//2、参数模板化
template <class T1, class T2>
void printPerson2(Person<T1, T2>&p)
{
	p.showPerson();
	cout << "T1的类型为： " << typeid(T1).name() << endl;
	cout << "T2的类型为： " << typeid(T2).name() << endl;
}
void test02()
{
	Person <string, int >p("猪八戒", 90);
	printPerson2(p);
}

//3、整个类模板化
template<class T>
void printPerson3(T & p)
{
	cout << "T的类型为： " << typeid(T).name() << endl;
	p.showPerson();

}
void test03()
{
	Person <string, int >p("唐僧", 30);
	printPerson3(p);
}

int main() {

	test01();
	test02();
	test03();

	system("pause");

	return 0;
}
