Remarks:WhenTis an array type, this constructor shall not participate in overload resolution unless the expressiondelete[] pis well-formed and eitherTisU[N]andY(*)[N]is convertible toT*, orTisU[]andY(*)[]is convertible toT*. ... To support this, the member typeelement_typeis now defined...
In the example, we are creating simple object N and a pointer to the object ptrN and accessing the member functions by using simple object N and the pointer to the object ptrN.C++ program to access member function by pointer#include <iostream> using namespace std; class Number { private:...

{ std::cout << "Data: " << data << std::endl; // 'this' points to a const object // Uncommenting the next line will cause an error because 'this' is const // data = 10; // Error: cannot modify 'data' in a const member function } // Static member function (no 'this' ...
Another example of using this pointer is to return the reference of current object so that you can chain function calls, this way you can call all the functions for the current object in one go. Another important point to note in this program is that I have incremented the value of object...
Return Pointer from Functions in C++ - Learn how to return pointers from functions in C++. This tutorial provides clear examples and explanations to help you master this important C++ concept.
a: 10, ref_a: 10 a: 100, ref_a: 100 Here,ref_ais the reference variable ofa, we can use it anywhere to access, edit the value ofa, in this program we are accessing and changing the value ofathroughref_a. Advertisement Advertisement...
Null pointers can indicate the absence of an object or can be used to indicate other types of error conditions. In general, a function that receives a pointer argument almost always needs to check if the value is null and handle that case differently (for example,freedoes nothing when a nul...
