C++ this Pointer

• In C++ programming, this is a keyword.
• this is a local object pointer in every instance member function which contains address of the current object.
• You can not change the value in this pointer ( this can not be modified ).

WHEN TO USE THIS POINTER

• when there is name conflict between instance member variable and local variable.
• whenever it is required to represent current object in instance member function.

Following is the code to support above statements.

#include<iostream>

using namespace std;

class Test

{

private:

   int x;

public:

   void setX (int x)

   {

this->x = x;

   }

   void print() { cout << "x = " << x << endl; }

};

 int main()

{

   Test obj;

   int x = 20;

   obj.setX(x);

   obj.print();

   return 0;

}
