C++ – Different methods for instantiating an object in C++

c++object

What is the difference between this:

Myclass *object = new Myclass();

and

Myclass object = new Myclass();

I have seen that a lot of C++ libraries like wxWidgets, OGRE etc use the first method… Why?

Best Solution

Myclass *object = new Myclass(); //object has dynamic storage duration (usually is on the heap)
Myclass object; //object has automatic storage duration (usually is on the stack)

You create objects with dynamic storage duration (usually on the heap) if you plan on using them throughout a long period of time and you create objects with automatic storage duration (usually on the stack) for a short lifetime (or scope).
