HEAP POINTER Meaning and
Definition
-
A heap pointer is a term commonly used in computer science and programming languages, particularly in the context of dynamic memory allocation. It refers to a unique address or reference that points to a specific memory location within the heap memory area. The heap is a region of memory where dynamic memory allocation takes place, allowing programs to request and release memory during runtime.
In many programming languages like C, C++, or Java, the heap pointer is a variable that holds the memory address of the beginning or first memory location of an allocated block of memory from the heap. This allocated memory can then be used to store data or objects that need to persist beyond the scope of the function or block in which they were created.
The heap pointer is crucial for managing dynamically allocated memory since it allows the program to access and manipulate the allocated memory. It enables the program to perform operations like reading or writing data stored in the allocated memory block, resizing or freeing memory, and keeping track of the allocated memory blocks to prevent memory leaks or accessing invalid memory locations.
In summary, a heap pointer is a variable that holds the memory address of an allocated memory block in the heap. It plays a vital role in managing dynamic memory allocation, allowing programs to efficiently allocate, access, and deallocate memory during runtime.

Etymology of HEAP POINTER
The term "heap pointer" is composed of two words: "heap" and "pointer".
1. "Heap": The word "heap" in computer science refers to a region of dynamic memory that is allocated for dynamic data structures, such as objects or variables, during program execution. It is a memory pool used for dynamic memory allocation. The term "heap" originated from the idea that memory in this region is allocated and deallocated in a heap-like structure.
2. "Pointer": In computer science, a "pointer" is a programming language data type that stores the memory address of another value located in computer memory. It "points" to the memory location of a specific value or data structure.
When combined, "heap pointer" refers to a variable or data structure that contains the memory address pointing to an allocated location within the heap. It is typically used to keep track of dynamically allocated objects or data in programs.
