/*-----
  Signature: main: void -> int

  Purpose: demonstrate a dynamically-allocated array of boas
  
  Examples: when this is run, if the user enters 3 when prompted,
            then the following will be printed to the screen:
boa at index 0:
color:  green
length: 6
food:   alligators

boa at index 1:
color:  green
length: 7
food:   alligators

boa at index 2:
color:  green
length: 8
food:   alligators
