  1. What is This pointer?

  2. What is This pointer? What’s in it for you ? What is this pointer ? Syntax of this pointer Working of this pointer Accessing the executing object using this pointer Features of this pointer

  3. What is This pointer? In C++, This is a keyword that is used to represent an object that invokes the member functions. It automatically points to the object for which the object is being called. .

  5. Syntax of This pointer Syntax for referring instance variable: this->class_variable = value; Syntax for referring to current object of class : this*

  6. Working of This pointer This keyword represents the address of the current instance of the class. The this pointer acts as an implicit(not in a direct way) parameter to all the member functions and is automatically passed to the member function when it is called.

  7. Accessing the executing object using this keyword #include<iostream> using namespace std; class O { public: void display() { cout<<"The address of object is : "; cout<< this; } }; int main() { O obj; obj.display(); return 0; }

  8. Features of this pointer distinguish data members members from local variables One of the features of this pointer is that it makes the members of the class readable by distinguishing between the class members and the parameters with the same name. void Set(int var) { this->var=var; }

  9. Features of this pointer Method chaining in C++ Method chaining is a very useful feature of this pointer. It helps in chaining the methods together for ease and cleaner code. Example: Obj->set(8)->replace(9)->inc(12);
