C uses malloc() and calloc()functions to allocate memory dynamical at run time. Similarly, it uses the function free() to free dynamicallyallocated memory. We use dynamic allocation techniques when it is not known in a...
It is possible to take address of amember of a class and assign it to a pointer. The address of a member can be obtained by applying the operator & to a “fully qualified” class member name. A class member pointer...
The constructors can also be used to allocate memory while creating objects. This will enable the system to allocate the right amount of memory for each object when the objects are not of the same size, thus resulting in...
We can use pointers not only to the base objects but also to the objects of derived classes. Pointers to objects of a base class are type-compatible with pointers to objects of a derived class. Therefore, a single point...
