Shortest and best way to “reinitialize”/clean a class instance

Question

I will keep it short and just show you a code example:

class myClass
{
public:
  myClass();
  int a;
  int b;
  int c;
}

// In the myClass.cpp or whatever
m         


        

Answer 1

myUsedInstance = myClass();

C++11 is very efficient if you use this form; the move assignment operator will take care of manually cleaning each member.
