【项目2-两个成员的类模板】 

　　设有如下的类声明：

<code class="hljs cs has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background: transparent;">class  Test{

（1）试将此类声明改为类模板声明，使得数据成员data1和data2可以是任何类型。 

（2）请为该类增默认构造函数、带两个参数分别对应两个数据成员初值的构造函数，以及复制构造函数。

#include <iostream>

using namespace std;

template<class T1,class T2>

class  Test{

public:

    Test(){}

    Test(T1 d,T2 a):data1(d),data2(a){}

    template<class T3,class T4>Test (Test<T3,T4> &text)

    {

        data1=text.data1;

        data2=text.data2;

    }

  void SetData1(T1 val) { data1=val; }

  void SetData2(T2 val) {data2=val; }

  T1 GetData1()  { return data1; }

  T2 GetData2() { return data2; }

private:

  T1 data1;

  T2  data2;

};

int main()

{

    Test<int,double> asd(3,4.5);

    cout<<asd.GetData1()<<endl;

    cout<<asd.GetData2()<<endl;

    Test<int,double> qwe(asd);

    cout<<qwe.GetData1()<<endl;

    cout<<qwe.GetData2()<<endl;
}

复制构造函数要特别注意！！！记住使用方法！！！！！！！！！
