// Election Good Example

// A program to read in the number of votes each of two candidates received
//   in a number of precincts, then compute the winner of the election.
//

/* DEVELOPMENT NOTES:
((Note: this is not something you should include in your own programs; this is included here to aid
         in your understanding and to provide additional context for the program.))
This is a BAD version of the program that has lots of redundancy and very
  little structure.
