The Stack Data Structure in C and C++. The stack is a common data structure for representing things that need to maintained in a particular order. For instance, when a function calls another function, which in turn calls a third function, it's important that the third function return back to the second function rather than the first.
The definition of a stack is a somewhat orderly pile. An example of a stack is nine books sitting on a table, one on top of another. To stack is to arrange in a pile. An example of to stack is to pile up pieces of firewood into a compact space.
