Overloading a Function Template

Overloading a Function Template

We can overload the generic function means that the overloaded template functions can differ in the parameter list.

Example:

#include <iostream>  
using namespace std;  
template<class X> void fun(X a)  
{  
    std::cout << "Value of a is : " <<a<< std::endl;  
}  
template<class X,class Y> void fun(X b ,Y c)  
{  
    std::cout << "Value of b is : " <<b<< std::endl;  
    std::cout << "Value of c is : " <<c<< std::endl;  
}  
int main()  
{  
   fun(10);  
   fun(20,30.5);  
   return 0;  
}  

/*
Output: 

Value of a is : 10
Value of b is : 20
Value of c is : 30.5
*/

In the above example, template of fun() function is overloaded.
