what is this pointer 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.
Friend functions do not have a this pointer,
because friends are not members of a class.
Only member functions have a this pointer.
pointer in c++
int* pointVar, var;
var = 5;
// assign address of var to pointVar
pointVar = &var;
// access value pointed by pointVar
cout << *pointVar << endl; // Output: 5
In the above code, the address of var is assigned to the pointVar pointer.
We have used the *pointVar to get the value stored in that address.
