Example Program For This Pointer

This code snippet creates a Counter class with multiple methods to GetCount methods. The first method i.e., GetCount_Pointer returns the value of this pointer which is simply an address of the calling object. The GetCount_Copy method returns this while the return type is a Counter type object. So, this function will return a deep copy of the calling object which means modifying the returned

In C, this pointer is used to represent the address of an object inside a member function.For example, consider an object obj calling one of its member function say method as obj.method.Then, this pointer will hold the address of object obj inside the member function method.The this pointer acts as an implicit argument to all the member functions.

Example of this Pointer. Let us try the following example to understand the concept of this pointer . include ltiostreamgt using namespace std class Box public Constructor definition Boxdouble l 2.0, double b 2.0, double h 2.0 cout ltltquotConstructor called.quot

Acc. to Object Oriented Programming with c by Balaguruswamy. this is a pointer that points to the object for which this function was called. For example, the function call A.max will set the pointer this to the address of the object. The pointer this is acts as an implicit argument to all the member functions.

In the above example, once we have called the function destroy on an object pointed by pointer ptr, it is safe to call the function displayText because it is not accessing any data member inside the function body. But, if function bar is called, the program will crash because we are trying to access values from a dangling pointer pointer not pointing to a valid memory location.

In C programming, this is a keyword that refers to the current instance of the class. A class object can access itself using this pointer inside its member functions. Understanding this pointer serves as a key prerequisite when we need to operate within object-oriented structures for functions, such as self-reference calls, method chaining, and operator overloading.

Within our member functions, we have access to a specific keyword this. The this keyword stores a pointer to the object that our member function was called on.. For example, if we were to call SomeObject.SomeFunction, within the body of SomeFunction, the this keyword would contain a pointer to SomeObject.. Below, we show this in action. We're logging out the address of SomeObject using

Note Friend functions do not have this pointer, because friends are not members of a class. Only member functions including constructors have quotthisquot pointer. Syntax to use this pointer in C this this-gtmember-identifier. Using this pointer inside Constructor in C. Let us understand this pointer with an example. Please have a look at

The this pointer holds the address of current object, in simple words you can say that this pointer points to the current object of the class. Let's take an example to understand this concept. C Example this pointer. Here you can see that we have two data members num and ch. In member function setMyValues we have two local variables having same name as data members name.

For a class X, the type of this pointer is 'X '. Also, if a member function of X is declared as const, then the type of this pointer is 'const X ' see this GFact In the early version of C would let 'this' pointer to be changed by doing so a programmer could change which object a method was working on. This feature was eventually removed
