This Pointer Example in C++


Every object in C++ has access to its own address through an important pointer called this pointer. The this pointer is an implicit parameter to all member functions. Therefore, inside a member function, this may be used to refer to the invoking object. ... Only member functions have a this pointer.

Example Program:

Find out the area of rectangle using this pointer in C++

Source Code

using namespace std;
class Rectangle
private :
    int length;
    int breadth;
public :
    Rectangle(int length=0,int breadth=0)
        this->breadth=breadth ;
    int area() 
        return length*breadth;
int main()
    Rectangle r(10,5);
    cout<<"Area : "<<r.area();
    return 0;
