SafeStack Solution.

Use an instance of stack from <string to hold

Stack object data structures do not contain code to throw an exception when a stack.pop() function is called on an empty stack. This is due to the fact that it is easy to establish this exception handing elsewhere. Create a class named SafeStack that implements a stack of strings. 

·         Use an instance of stack from <string to hold string values and implement the same interface as the data type. However, your implementation (class) should throw an exception if an attempt is made to remove a value from an empty stack.
