What is stack memory and heap memory?

Question

What is stack memory and heap memory? Why are they both used? What new is for?

Answer 1

stack:
it is for functions. each function will be loaded in stack.
Heap:
it is for variables in each function. all the variables for that particular function will be loaded in heap.

when your recursive function does maximum calls for self, you'll get a stack overflow.

when your function uses a lot of variables and when they try to store the values but no space, you'll get out of memory error.
