C++：类模板遇到继承

Posted 2021-08-29 studying~

1.类模板遇到继承 在继承时,继承的类必须是一个模板类<>
2.类模板遇到继承,可以将子类写成类模板

#define _CRT_SECURE_NO_WARNINGS
#include <iostream>

#include <stdlib.h>
#include <string>
using namespace std;

template <class T>
class Base
{
public:
	Base(T a)
	{
		this->a = a;
	}
	T a;
};

class Son1 :public Base<int>                //1
{
public:
	Son1(int x1, int  a) :Base<int>(a), x(x1)
	{}
	int  x;
};

template <class  T1,class T2>              //2
class  Son2 :public Base<T2>
{
public:
	Son2( T1 x1,T2 a):Base<T2>(a), x(x1)
	{}
	T1 x;
};
void test01()
{
	Son1 p(10,20);
	Son2<int, string> p2(10,"lucy");
}
int main()
{

	return 0;
}
