Question

Please post following code with criteria below... please leave as many comments as possible

Exam Four: the election

Outcome:

• Student will demonstrate all core competencies from this class:
  • Program Design (design tools)
  • Variables
  • Decision
  • Error Checking
  • Looping
  • Functions
  • Arrays

Program Specifications:

Let’s pretend that we are tracking votes for the next presidential election. There will be two candidates: Ivanka Trump and Michele Obama.

You can assume that there are fifty states casting votes. You will do not need to deal with the names of the states, you can assume that state 0 = the first state and state 49 = the last state.

This program will have menu system. The menu will at least have the following options:

***********************************************************

** CNN VOTER COLLECTION PROGRAM MAIN MENU **

***********************************************************

1. Enter Votes from a state for Ivanka Trump
2. Enter Votes from a state for Michele Obama
3. Display total votes for each candidate
4. Display the all votes for a selected candidate in order
5. List the state number(s) where Trump and Obama received the exact same number of votes
6. For each candidate display the highest number of votes from any state, the lowest number of votes from any state, the average number of votes from all states.
7. Election is over, Exit Program

Comments:

When the user presses (1) or (2) from above, the program will ask the user to enter a value for the NEXT state. You can assume that the first time they press (1) from the main menu they were entering votes for state ZERO. The second time for the FIRST state. The user will only be typing a single number (the number of votes for that state). The control of the program will bounce back to the main menu.

Note: The votes are not from a single voter, but from ALL votes cast for that candidate from that state.

When the user selects (3) you will simply show the votes by state for each candidate.

State Trump Obama

0 87876 78877

1 98776 576788

When the user presses (4) sort the votes from low to high and display them.

When the user presses (5) the program will create a statement or statements such as:

Obama and Trump each got 2345 votes from state 8.

When the user presses (6) the program will display by state the lowest number of votes for a candidate from any one state, the average votes by a candidate from any one state.

When the user presses (7)…you figure it out.

Submission Requirements:

Your source code must have a comment header and comments within the code. If you name is not in the comments, you will receive 0 points for this exam. You must provide a well written design tool that matches the code and was generated by a computer application. You must do error checking in at least 2 places within the code. You must have a bubble sort and some type of search function. Everything must be written in functions. Main can only have variables, a loop and a switch.

You must place your design tool in the src folder. You must use Windows compress. You must upload your zipped document to the exam thread.

YOU CANNOT:

• Use global variables
• Use the word goto
• Use the break command outside a case statement
• Use POINTERS, this is an advanced concept taught in C
• Use a 2D array, this is an advanced concept taught in C
