Question

I have a class eg

class test{

   public:
      somedatahere
      test();
     ~test();
   private:
       string mystring;

}

In this class the constructor reads the contents of a file in variable mystring.My question is :

Does mystring gets freed when the class destructs or I must free it manually? How can I free mystring ?

Answer 1

Since mystring is part of the object, it will go out of scope when the object does. There’s no need to “manually” free it, and indeed you can’t.

This would be different if mystring was a pointer to memory allocated with new (or new[]), then you’d have to manually delete (or delete[]) it from your destructor.
