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(,67.8);
     if(a.comp())
         printf("i>j\n");
     else printf("i<=j\n");
     a.print_Type();
     return ;
 }
