Try this:


      1 #include <iostream>
      2
      3
      4 template <class T>
      5 class pair
      6 {
      7 public:
      8     pair(T first, T second) {value1=first; value2=second;}
      9     T module () {return 0;}
     10
     11 private:
     12     T value1;
     13     T value2;
     14 };
     16
     17 template <>
     18 class pair <int>
     19 {
     20 public:
     21     pair (int first, int second) {value1=first; value2=second;}
     22     int module (  ) { return (value1 % value2); }
     23 private:
     24     int value1;
     25     int value2;
     26 };
     35
     36 int main (void)
     37 {
     38     pair <int>   myints (100, 75);
     39     pair <float> myfloats (100.0, 75.0);
     40
     41     std::cout << myints.module() << '\n';
     42     std::cout << myfloats.module() << '\n';
     43
     44 return 0;
     45 }
     46
