C++STL_类模板举例

#include<stdio.h>
#include<typeinfo.h>

template <class T1,class T2>
class A{
    T1 i;
    T2 j;
    public:
        A(T1 t1,T2 t2){i=t1;j=t2;}
        bool comp(){return i>j;}
        void print_Type();
};
template <class T1,class T2>
void A<T1,T2>::print_Type()
    {
        printf("i的类型是%s\n",typeid(i).name());
        printf("j的类型是%s\n",typeid(j).name());
    }
int main(void)
{
    A<int,double> a(3,67.8);
    if(a.comp())
        printf("i>j\n");
    else printf("i<=j\n");
    a.print_Type();
    return 0;
}
