Type condition in template

Question

Is it possible to build only some part of the code given the type of the template in C++ ? It would be something lake that :

#include 

using         


        

Answer 1

Use template specialization:

template
void printType(T param)
{
   // code for the general case - or omit the definition to allow only the specialized types
}

template<>
void printType(char* param)
{
   // code for char*
}

template<>
void printType(int param)
{
   // code for int    
}

// ...
