V.18 Write a program that emulates a stack using a linked list. Implement the menu using an enumerated type. Write functions to implement each of the following tasks. Push Pop IsEmpty Peek Size Then provide a menu for the user to choose one of these 5 options (error check the input to ensure it is in the proper range). If they choose push allow them to enter in a name, gender, and age. If they choose pop, let them know all the info about the person who is being removed (if the list is empty, let them know). If they peek, show them who is at the top of the list. Use an enumerated type for the menu. If they choose size, tell them how many people are in the list. Validate the user input. →This lab will must be demonstrated. a Turn in as a single PDF file (IN THIS ORDER) 1. screen I/O-pasted into a text file within eclipse and printed with line numbers. 2. Your header file. 3. a listing of main.cpp (conforming to style discussed in class) 4. a listing of your functions 5. a listing of your print heading function OUTPUT MESSAGE FORMAT Check below for a more detailed description of the expected input and output Invalid command inputs Out of range error: **** The number 12 is an invalid entry **** Please input a number between 0 and 5 **** **** Please input a NUMBER between 0 and 5* Size For more than one: There are 2 people on the stack. For one: There is one person on the stack. For an empty stack: Nobody is on the stack! Peek if the stack is empty: There is nobody to PEEK at !! **** Empty For an empty stack: Yes, the stack is empty. For a non-empty stack: The stack is NOT empty. Pop If the stack is empty: Can't POP from an empty stack!
