Create a C++ dictionary app with a loop that prompts the user for words to look up.

  • ??Study the https://github.com/fromlc/ex9_dictionary.git
  • ??Use the global string arrays dict::words and dict: defs for words and definitions. You may add words and their definitions if you wish.
  • ??Good code recognizes commands typed in any case, but for this exercise search for the word exactly as the user types it.
  • ??Don’t worry about validating user input – assume valid input for this exercise.
  • ??Get your lookup working first, and only then should you code the user prompt loop.
  • ??Write a function named lookup_word) that looks up words in the dict:words array.
  • ??Your function should accept two arguments:
  • ??a string reference parameter for the word to look up, and
  • ??a string reference parameter to hold the returned definition.
  • Your function should return an int that holds either:
  • ??the index of the word’s definition in the dict::words and dict::defs arrays, OR
  • o -1 if the word is not found in dict.:words array

    • ??In your function lookup_word(), call the string compare() function in a loop to search for the a word
    • ??Start by searching for a hard-coded word (“cat” or “dog”).
    • ??Once you can display a word’s correct definition, add the user prompt loop and look up the user’s words.
    • ??Terminate your loop when the user types
      “quit” in all lowercase.
