Detailed explanation-1: -Heaps memory is allocated during the execution of programmers’ instructions. It is crucial to highlight that the name heap has nothing to do with the heap data structure. It is termed a heap because it is a collection of memory space that programmers can allocate and deallocate.

Detailed explanation-2: -Allocation. The heap is a large area of memory available for use by the program. The program can request areas, or “blocks”, of memory for its use within the heap. In order to allocate a block of some size, the program makes an explicit request by calling the heap allocation operation.

Detailed explanation-3: -Heap Memory is used for Dynamic Memory Allocation of Java objects and JRE classes that are created during the execution of a Java program. Heap memory is allocated to objects at runtime and these objects have global access which implies they can be accessed from anywhere in the application.

Detailed explanation-4: -In C, dynamic memory is allocated from the heap using some standard library functions. The two key dynamic memory functions are malloc() and free(). The malloc() function takes a single parameter, which is the size of the requested memory area in bytes. It returns a pointer to the allocated memory.
