Memory allocation for objects

The memory space of objects is allowed when they are declared and not when the class is specified. Member functions are created and stored in the memory space only once when they are defined in a class specification. As all objects in this class use the same member functions, no separate space is allowed for member functions when objects are created.

Only the space for member variables is allocated individually for each object. Separate memory locations for objects are crucial because member variables will contain different data values for different objects.
