Frage 52. What is a heap and a stack?
There are 2 kinds of heap – 1: a chunk of memory where data is stored and 2: a tree
based data structure. When we talk about the heap and the stack we mean the first kind
of heap. The stack is a LIFO data structure that stores variables and flow control
information. Typically each thread will have its own stack.
