Illustrates the term heap in data structures?
Expert
The heap is assigned where malloc(), calloc(), and realloc() find memory.
Getting memory by the heap is much slower than getting this from the stack. Conversely, the heap is much more flexible than the stack. Memory can be assigned at any time and de-allocated in any order. This memory isn't deallocated automatically; so you should call free ().
Recursive data structures are almost all the time implemented along with memory from the heap. Strings frequently come from there too, particularly strings which could be very long at runtime. When you can keep data in a local variable (and assign this from the stack), and your code will run faster than when you put the data on the heap. Occasionally you can use a better algorithm when you use the heap faster, or additionally robust, or more flexible. This is a tradeoff.
If memory is assigned from the heap, it is available till the program ends. That's great when you remember to deallocate this when you're done. If you not remember, it's a problem. A memory leak is several allocated memory that's no longer required but isn't deallocated. If you contain a memory leak inside a loop, you can utilize up all the memory on the heap and not be capable to get any more. (While that happens, the allocation functions return a null pointer.) In several environments, if a program doesn't deallocate everything this allocated, memory stays unavailable still after the program ends.
