While C++ is always fun (except for C++ build times, of course), there are moments where we really get to have a blast. For me, the following C++ quiz is one of these moments. I’m not sure what did it for me. Was it the thrill of solving a challenge, or just the chance to play around with the language like a kid.

I hope you’ll have as much fun as I had.

Thanks to Anders Schau Knatten from CppQuiz for creating this quiz!

The Quiz!

#include <iostream>

template<class T>

void f(T) { std::cout << 1; }


void f<>(int*) { std::cout << 2; }

template<class T>

void f(T*) { std::cout << 3; }

int main() {

    int *p = nullptr

    f( p );



Before I spoil everything and reveal the answer,  here’s a nice hint for you:

A declaration of a function template being explicitly specialized shall precede the declaration of the explicit specialization. During overload resolution, only the base function templates are considered, not specializations.
