Question

C++...This program is broken down into phases for your convenience only. Please turn in only the final phase. Before turning in your program, please make sure that it does something reasonable if the user enters a negative number the first time.

Phase I: Write a program for a theater that will keep track of how many people in each of 5 age categories attended a particular movie. Use the 5 age categories listed below in the sample screen output. The user will enter a number of ages, entering a negative number when there are no more ages to enter. Your program will then report on how many people in each age group attended. Sample screen output:

Enter age of attendee (-1 to quit): 34 Enter age of attendee (-1 to quit): 16 Enter age of attendee (-1 to quit): 68 Enter age of attendee (-1 to quit): 53 Enter age of attendee (-1 to quit): 39 Enter age of attendee (-1 to quit): 23 Enter age of attendee (-1 to quit): 21 Enter age of attendee (-1 to quit): -1 age 0 to 18: 1 age 19 to 30: 2 age 31 to 40: 2 age 41 to 60: 1 over 60: 1

Phase II: Modify your program so that, in addition to the report that the program currently produces, it also gives the average age of the people in attendance, the age of the oldest person in attendance, and the age of the youngest person in attendance. Sample screen output:

Enter age of attendee (-1 to quit): 34 Enter age of attendee (-1 to quit): 16 Enter age of attendee (-1 to quit): 68 Enter age of attendee (-1 to quit): 53 Enter age of attendee (-1 to quit): 39 Enter age of attendee (-1 to quit): 23 Enter age of attendee (-1 to quit): 21 Enter age of attendee (-1 to quit): -1 age 0 to 18: 1 age 19 to 30: 2 age 31 to 40: 2 age 41 to 60: 1 over 60: 1 The average age was 36. The youngest person in attendance was 16. The oldest person in attendance was 68.

Phase III: Modify your program so that it also asks each attendee for a theater concession stand purchase. The attendee must make a selection based on the following choices …

1 - Soft Drink (such as Coca Cola, ICCEE, Mineral Water etc...)

2 - Popcorn

3 - Nachos       

4 - Soft drink & Popcorn

5 - Soft drink & Nachos

6 - Organic and Gluten-free snacks       

7 – None

The program output should now also provide a theater concession stand sales summary with a count of each category purchased.

Note: Include a validation routine to ensure that a correct choice is input for each attendee.

Check the sample screen output below for the final formatted display of theater statistics.
