Question from the C++ - Fundamentals test

Template function to check the type of a variable in C++ using constexpr.

Medium

What is the output of the following code?

#include <iostream>
#include <type_traits>

template<typename T>
void checkType(T) {
   if constexpr (std::is_integral<T>::value) {
       std::cout << "Intégral" << std::endl;
   } else if constexpr (std::is_floating_point<T>::value) {
       std::cout << "Flottant" << std::endl;
   } else {
       std::cout << "Autre" << std::endl;
   }
}

int main() {
   checkType(5);
   checkType(3.14);
   checkType("Test");
   return 0;
}
