Priority between normal function and Template function

Question

In the following code, the main function uses normal function instead of Template function.

#include 

using namespace std;

template 

        

Answer 1

To call the template method in this case, you need to invoke the method explicitly with num(5) instead of num(5). Although the compiler can infer, non-generic method is preferred to a generic one. You can take a look at this behavior here http://ideone.com/ccDJP.
