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

You may want to consider using placement new. This will allow you to use the same memory but call the constructor again.

Don't forget to call the destructor before using placement new, however.
