C++ Variadic Function Templates of Known Type

Question

I\'m currently trying to get my head around some of the things I can do with variadic template support. Let\'s say I have a function like this -

template <         


        

Answer 1

A variation of the top answer which will reject implicit conversion to int , if that is your preference:

#include 

void foo(int);

template
void foo(Arg1 first, Args... more)
{
   static_assert(std::is_same_v, "foo called with non-int argument");
   foo(first);
   foo(more...);
}
