Static variable inside template function

Question

In C++, if you define this function in header.hpp

void incAndShow()
{
  static int myStaticVar = 0;
  std::cout << ++myStaticVar << \" \" <<         


        

Answer 1

• templates will only actually be turned into code once they're instantiated (i.e. used)
• headers are not to be used for implementation code, but only for declarations
