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.

May 7, 2024 · What is a Pointer in Programming? Pointer is a variable which stores the memory address of another variable as its value. The data stored in the memory address can be accessed or manipulated using pointers. Pointers allows low-level memory access, dynamic memory allocation, and many other functionality.

Oct 8, 2013 · In computer science, a pointer is a programming language data type whose value refers directly to (or "points to") another value stored elsewhere in the computer memory using its address. Obtaining or requesting the value to which a …

In computer science, a pointer is a variable whose value is a location in the computer's memory. [1] . If Rick stands in a room and points to his friend Sally, then Rick is a pointer whose value is Sally's location. A programmer must dereference the pointer to retrieve the object it points to. Pointers do not take up much memory (RAM).

Apr 15, 2025 · Pointer initialization means assigning some address to the pointer variable. In C, the (&) addressof operator is used to get the memory address of any variable. This memory address is then stored in a pointer variable. Example: In the above statement, pointer ptr store the address of variable x which was determined using address-of operator (&).

Once we declare a pointer variable, we must make it to point to something. We can do this by assigning or initializing to the pointer the address of the variable you want to point to as in: iptr = &num ;

Pointers, found in languages like C and C++, allow direct access and manipulation of memory addresses, making programs both efficient and powerful—but also more complex. In this article, we will explore what pointers are, how they work, and their various applications.

May 5, 2022 · 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.

Ans. Pointers are variables in computer science that store the memory address of another variable. They allow the programmer to directly manipulate the memory location of a variable and access or modify its value.

A pointer is a variable that stores the memory address of another variable or object in a computer's memory. In computer science, pointers are used to manipulate memory directly and to enable dynamic memory allocation. Pointers are often used in low-level programming languages such as C and C++ to implement complex data structures and ...
