1. Compare and contrast templates and polymorphism.
2. Discuss advantages of throwing an exception as opposed to returning an error code.
3. Create a template of a stack with constructor, destructor, pop, push, and peek operations. Use a class called stack_error and two derived error classes stack_full and stack_empty. Write two different functions that pump in numbers in a stack of integers until the stack is full and pump out numbers from the stack until stack is empty. In one function, catch stack_error exceptions in the other catch the stack_full and stack_empty exceptions individually.
