Member Function Template

When the member functions of a template class defined outside of the class, each function preceded by the function template.

            It takes the following general format:

template<class  T>  return_type    class_name <T> :: memberfunction_name(arguments) {              - - - - - - - -              Body of member function              - - - - - - - -

                               }

/*Program to illustrate member function template */

#include<iostream.h>
template <class T>
class Sample
{
           T   x;
           public:
                     Sample(T  a)
                          {  
                                  x = a;
                           }
                      void  show( );
}; 
template <class T>
void Sample <T> : : show( )       //member function template
{
         cout <<”Input:”<< x <<endl;
}
int  main( )
{
          Sample <int> S1(10);
          Sample <float> S2(8.45);
          S1.show( );
          S2.show( );
          return  0;
}

Output:           Input: 10

                        Input: 8.45
