This program will implement some simple stack-based arithmetic. The main file I will provide will handle the parsing of input for testing (as well as test your stack implementation), but will call your stack implementation to store its "memory".
stack(int initialSize)(a constructor)
void push(int value)
int size()("height" of stack)
int psize()(number of available slots)
friend... operator<<(...)(a constructor)
