Question

Which one do you prefer to delete objects? Especially in QT, but other practices are also welcome. These two alternatives seem same to me, are they?

1. Bound to another class, and destroy when it is destroyed.

   SomeClass::SomeClass{
    socket_ = new QTcpSocket(this);
   }
   

or

2. Destroy in the destructor of class

   SomeClass::SomeClass{
    socket_ = new QTcpSocket();
   }
   
   SomeClass::~SomeClass{
    delete socket_;
   }
   

Answer 1

When in Rome, do as the Romans do. If your framework uses one method (for example Qt relies on parent-child relationship), use this method in your code.

Of course don’t forget about general good memory management practices: create object on stack whenever it’s possible, use shared pointers, etc.
