Pointer to Classes Example in C++


Pointer to C++ Classes. A pointer to a C++ class is done exactly the same way as a pointer to a structure and to access members of a pointer to a class you use the member access operator -> operator, just as you do with pointers to structures. Also as with all pointers, you must initialize the pointer before using it.

Example Program:

Find out the area of rectangle using Pointer to Classes in C++

Source Code

using namespace std;
class Rectangle
public :
    int length;
    int breadth;
    int area()
        return length*breadth;
    int perimeter()
        return 2*(length+breadth);
int main()
    Rectangle r;
    cout<<"Area : "<<r.area();
    return 0;
