In computer science, a pointer is an object in many programming languages that stores a memory address. This can be that of another value located in computer memory, or in some cases, that of memory-mapped computer hardware.

Jul 10, 2022 · Pointers: A pointer is a variable that holds the memory address of another variable. A pointer needs to be dereferenced with the * operator to access the memory location it points to. References: A reference variable is an alias, that is, another name for an already existing variable.

In many object-oriented programming languages, this (also called self or Me) is a variable that is used in instance methods to refer to the object on which they are working. The first OO language, SIMULA 67, used this to explicitly reference the local object. [1] : 4.3.2.3 C++ and languages which derive in style from it (such as Java, C#, D ...

ポインタ (英: pointer) とは、コンピュータプログラミングにおいて、変数や定数、サブルーチン（関数）などが置かれたメインメモリ上の番地（メモリアドレス）を格納するための特殊な変数のこと 。 あるオブジェクトがなんらかの論理的位置情報に基づいてアクセスできるとき、それ …

A pointer allows a function or a program to access a variable outside the preview function or a program ,using pointer program can access any memory location in the computer’s memory.

Advantage of pointer. 1) Pointer reduces the code and improves the performance, it is used to retrieving strings, trees, etc. and used with arrays, structures, and functions.. 2) We can return multiple values from a function using the pointer.. 3) It makes you able to access any memory location in the computer's memory.. Usage of pointer. There are many applications of …

A pointer is a variable that stores the address of another variable. Unlike other variables that hold values of a certain type, pointer holds the address of a variable. For example, an integer variable holds (or you can say stores) an integer value, however an integer pointer holds the address of a integer variable.
