A memory heap is a location in memory where memory may be allocated at random access. Unlike the stack where memory is allocated and released in a very defined order, individual data elements allocated on the heap are typically released in ways which is asynchronous from one another.
What are the stack and heap? Where are they located physically in a computer's memory? To what extent are they controlled by the OS or language run-time? What is their scope? What determines their ...
A heap must have each node satisfying the heap property, the max-heap property is that for every node i other then the root, Heap [Parent (i)] >= Heap [i] So at each node, the higher nodes have higher numbers, lower nodes have lower numbers. I understand this. But I can't see a use of a Heap other then to simply get the highest n numbers in a list.
Why are the runtime heap used for dynamic memory allocation in C-style languages and the data structure both called "the heap"? Is there some relation?
The heap is part of your process's address space. The heap can be grown or shrunk; you manipulate it by calling brk(2) or sbrk(2). This is in fact what malloc(3) does. Allocating from the heap is more convenient than allocating memory on the stack because it persists after the calling routine returns; thus, you can call a routine, say funcA(), to allocate a bunch of memory and fill it with ...
I am getting confused with memory allocation basics between Stack vs Heap. As per the standard definition (things which everybody says), all Value Types will get allocated onto a Stack and Reference
The heap is a bunch of memory that can be used dynamically. If you want 4kb for an object then the dynamic allocator will look through its list of free space in the heap, pick out a 4kb chunk, and give it to you. Generally, the dynamic memory allocator (malloc, new, et c.) starts at the end of memory and works backwards.
A heap is a tree data structure where higher levels of the tree always contain greater (or lesser, if it's set up that way) values than lower levels. "The" heap is a bunch of free RAM that a progr...
