Write the code
1. One argument used to justify the fact that the stack data structure in the standard library does not throw exception is that it is easy to add these facilities. Create a class SafeStack that implements a stack of strings. Use an instance of stack <string> to hold the underlying values, and implement the same interface as the data type. However, your class should throw an exception if an attempt is made to remove a value from an empty stack.
2. Write a program that can be used to demonstrate that the order in which catch clauses are listed is important.
