In this example, we will explain to you how to use this pointer in c++. To understand this topic it is necessary to have basic knowledge of C++. Please read this article carefully so that you can understand this pointer in c++.

This pointer and advantage of this pointer in c++

• Every object is a special pointer "this"  which points to the object itself. 

• this is a local object pointer in every instance member function containing the address of the caller object.

• this pointer access all member functions of the class but this pointer not to access static member functions of the class.

• this pointer can not be modified.

• It is used to refer caller object in the member function.

• this is a keyword.

• Friend functions do not have this pointer, because friends are not members of a class. Only member functions have this pointer.

• This pointer resolves the name conflict problem in a class.

Look take an example

#include<iostream> using namespace std; class rectangle { private: int length,width; public: void Setvalue(int length,int width) { // This pointer resolves the name conflict problem in class member variables and member function variables. this->length=length; //assignment left hand side private member varible this->width=width; } void showvalue() { cout<<"Area of Rectangle is: "<<length*width; } }; int main() { rectangle r1,*r2; r1.Setvalue(5,6); r1.showvalue(); getch(); }
