Guessing game program using functions General Requirements for project 2 Rewrite the program from project 1 using at least four user-defined functions other than the main function All functions (except the main function) will be defined as follows · The function prototype appears before the main o o o Comment describing what the function does appears directly under function prototype Formal variable names are not used in any prototype The functions definition appears after the main 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 getNumberOfGame, 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)3 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 * Make sure to follow the instructions carefully including using the exact function names with the exact letter cases (upper and lower case letters). Your programs are going to be tested using a unified main function that is developed for that purpose. If the unified main function does not compile this indicates inconsistencies in meeting the above requirements and will result in a zero grade. *

Explanation / Answer

Hello, I have a solution for you. Implemented everything as per the requirements. Defined following things in this answer.

//updated cpp code

#include<iostream>

#include<fstream>

#include<cstdlib>//library includes the definition of rand funcion (a random number generator) and the exit function

#include<ctime>//library includes the the definition of time funcion.

using namespace std;

/*declaring the number of guesses outside the main method, so that the intro method can use it*/

const int NUMBER_OF_GUESSES = 5;

/*method to display an intro message to the user*/

/*method to prompt the user to enter number of games, and returns it (1-4)*/

int getNumberOfGame();

/*this method will compare two characters, return 0 if they are equal, 2 if first one comes after second, else -2*/

int compareTwoCharacters(char,char);

/*method to conduct one game, with a given mystery character*/

        }

}

/*OUTPUT*/

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:

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

How many games do you want to play (1-4) 7

Invalid number of games, try again...

How many games do you want to play (1-4) 2

************************************

Let's play game 1

Enter a guess: s

the letter you are trying to guess comes before s

Enter a guess: e

the letter you are trying to guess comes before e

Enter a guess: b

the letter you are trying to guess comes after b

Enter a guess: c

the letter you are trying to guess comes after c

Enter a guess: d

You guessed it!!!

************************************

Let's play game 2

Enter a guess: s

the letter you are trying to guess comes before s

Enter a guess: f

the letter you are trying to guess comes after f

Enter a guess: j

the letter you are trying to guess comes after j

Enter a guess: l

the letter you are trying to guess comes after l

Enter a guess: o

the letter you are trying to guess comes after o

You did not guess the letter. It was p
