12.12 POINTERS TO USER DEFINED DATA TYPES

Earlier, we have seen pointers to basic data types. Pointers work exactly in same manner with user-defined data types like structures and objects. We have seen pointers pointing to structures in Chapter 3 “Moving from C to C++”. Let us see how the pointer works with objects.

Consider that we have defined a class “Student”.

class Student  { public:      int rollNum;      char name[40];      Student();      void show()) ;} ;

We can create an object of this class as shown below:

Student someName = new Student ;

Later we can handle data members and methods by using an arrow operator, i.e.,

someName->rollNum or

someName->show()

When we want an array of large number of ...
