In C, the library function malloc is used to allocate a block of memory on the heap . The program accesses this block of memory via a pointer that malloc returns. When the memory is no longer needed, the pointer is passed to free which deallocates the memory so that it can be used for other purposes.
Read moreHow is dynamic memory allocation done in C?
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.

Read moreWhat is the static memory allocation in C?
Static variable defines in one block of allocated space, of a fixed size . Once it is allocated, it can never be freed. Memory is allocated for the declared variable in the program. The address can be obtained by using ‘&’ operator and can be assigned to a pointer.
