將例9.14改寫爲在類模版外定義各成員函數

 

#include<iostream>
using namespace std;

template <class numtype>
class Compare
{
public:
    Compare(numtype a,numtype b);

    numtype max();

    numtype min();

private:
    numtype x,y;
};

template<class numtype>
Compare<numtype>::Compare(numtype a,numtype b)
{ x=a;y=b; }

template<class numtype>
numtype Compare<numtype>::max()
{
    return (x>y)? x:y;
}

template<class numtype>
numtype Compare<numtype>::min()
{
    return (x<y)? x:y;
}
int main()
{
    Compare<int>cmp1(3,7);
    cout<<cmp1.max()<<"整數"<<endl;
    cout<<cmp1.min()<<"整數"<<endl<<endl;
    Compare<float>cmp2(45.78,93.6);
    cout<<cmp2.max()<<"浮點"<<endl;
    cout<<cmp2.min()<<"浮點"<<endl<<endl;
    Compare<char>cmp3('a','A');
    cout<<cmp3.max()<<"字符"<<endl;
    cout<<cmp3.min()<<"字符"<<endl;
    return 0;
}
