Counting machine for ballots cast.

A game show allows contestants to ask the audience to help them choose a correct answer to a question from four possible answers. Audience members each have a small hand-held terminal on which they can press one of four buttons labelled A, B, C or D. As the audience vote, their selection is appended to a list. Once the time for voting has ended the results are collated and displayed to the contestant.

Success Criteria

Remember to add a comment before a subprogram, selection or iteration statement to explain its purpose.

Complete the subprogram called count_votes that:

  1. Takes a parameter called ballot that is the list of the votes cast.
  2. Counts the number of votes for A, B, C and D. Any other data in the list is ignored.
  3. Returns a list of the results. Index 0 is the count for A, index 1 is the count for B, index 2 is the count for C and index 3 is the count for D.

Complete the main program so that:

  1. The count_votes subprogram is called.
  2. The results of the vote are output.

Typical inputs and outputs from the program would be:

Answer A: 5
Answer B: 10
Answer C: 3
Answer D: 2
