This time it should use at least four user-defined functions other than the main function.

/*I am trying to rewrite the previous program assignment. This time it should use at least four user-defined functions other than the main function. I was able to do the first and second function's name but I am getting confused on third on fourth. Please help.

* The first function's name is introduction, which will print (show on the screen)

Welcome to the Letter Guessing Game

You will enter the number of games you want to play (1 - 4 games)

You have 5 chances to guess each letter

Let's begin:

--------------------------------

* The second function's name is getNumberOfGames, which asks the user about the number of games to

be played and returns the value. This function will validate the user input to make sure it is in

the desired range (1-4) inclusive, if the value is out of range the user is notified and asked again.

How many games do you want to play (1-4) 4

* The third function's name is compareTwoCharacters, which receives two parameters of type character

(e.g. the character to be guessed in that game and the character typed by the user). This functions

return 0 if the two characters are the same, returns 2 if the first parameter comes after the second

parameter, otherwise it returns -2.

* The fourth function's name is playOneGame, which receives one parameter of type character (the

character to be guessed in that game). This function returns true if the user won; otherwise will

return false. This function will handle all tasks to play one game (ask the user to enter their

guess, provide up to 5 chances to guess, provide a hint to the user, etc.). This function is going

to call the third function (i.e. compareTwoCharacters) to decide if the user has guessed the

correct answer or to provide a hint to the user.
