When should this pointer be used?

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.

Where pointers are used in real life?

You use pointers to build everything else, including higher level (more abstract, with more conveniences already built-in) data structures. Every real world example of software is a real world application of pointers. At the lowest level, all data structures are built on chunks of memory.

In which condition it is prefer to use pointer in a programming?

You should use pointers any place where you need to obtain and pass around the address to a specific spot in memory. You can also use pointers to navigate arrays: An array is a block of contiguous memory that has been allocated with a specific type.

What is this pointer explain its importance with an example?

Pointer is a variable that stores the address of another variable stored. Pointers are very useful in implementing Data Structure. Also, pointers are used to change the actual value of variable (call by address) which you will study in functions.

Why this pointer is used Mcq?

Explanation: The pointer which denotes the object calling the member function is known as this pointer. The this pointer is usually used when there are members in the function with same name as those of the class members.

Is this pointer necessary?

The “this” pointer is a hidden parameter implicitly added to any non-static member function. Most of the time, you will not need to access it directly, but you can if needed.

What are the application of this pointer?

It can be used to pass current object as a parameter to another method. It can be used to refer current class instance variable. It can be used to declare indexers.

What does this pointer point to?

The this pointer is a pointer accessible only within the nonstatic member functions of a class , struct , or union type. It points to the object for which the member function is called.

What is pointer explain with example in C++?

What are Pointers? In C++, a pointer refers to a variable that holds the address of another variable. Like regular variables, pointers have a data type. For example, a pointer of type integer can hold the address of a variable of type integer.

Which among the following is true this pointer can be used?

Which among the following is true? Explanation: The this pointer can be used to guard itself whenever self-reference is used.
