Laboratory 01: Guessing Game

Download the following files and place them in your working directory:

Starting code for this lab:

Lab01Files.zip //provided, completed files, refer to header files for method


PlayerGuessDriver.cpp //most of the work is in this file

range.txt //contains the two integers that define the range for the secret


build.bat //convenience file for compiling and linking

Guessing Game

In this lab, you will write a simple guessing game. The computer will generate a

random integer within a valid specified range, inclusive (min, max) read in from a

text file. The user then tries to guess the generated secret number. If the guess is

not correct, the user is told whether they are too high or too low. When the secret

number has been correctly guessed, the total number of guesses required is

reported. The user is then asked if they want to play again.

You will need to use my String, ReadFile, Keyboard, and Random structs to

complete this lab. To use these structs, you can refer to the method signatures in

the header files for each struct.

#include "Text.h"

#include "ReadFile.h"

#include "Random.h"

#include "Keyboard.h"

Complete the following methods:

int getSecret(int* range) //obtain a randomly generated secret number in the

range (started for you)

int* getRange() //get the name of the text file and read the range from the

text file (range is an int array of size 2, dynamically allocated using new,

delete pointers when finished with them)

int getGuess(int* range) //obtain a guess (ask again if the guess is not in the


GuessEnum processGuess(int guess, int secret) //determine whether a guess

is correct (return EXACT), too low (return TOO_LOW), or too high (return


int play(int* range, int secret) //loops until the secret number has been

guessed and returns the total number of guesses required (calls getGuess and


int main() //starts up a game and loops as long as the user wants to keep

playing (calls getRange, getSecret, and play, deletes the dynamically allocated

integer array)

I like to use many short methods when I write programs. This allows you to

increase the level of abstraction in your program, a term which you will hear

very frequently this semester. Sections of code are replaced by well-named method

calls. This improves the readability of your program.

Batch File

Typing at the command line every time that you want to compile and run can be

tedious. Instead, you can type your command line instructions into a text (batch)

file with the .bat extension. Then you can simply type the name of the batch file at

the command prompt followed by the drive letter of your jump drive (i.e. build e)

and all of your instructions listed in the batch file will automatically execute in

order. Take a look at build.bat to see the set of command line operations that you

can use to compile and link your work for this lab. If you don't need to compile

certain files, you can comment out the corresponding line with ::. This makes it

easy to select and deselect which files to compile.

Artificial Intelligence

Write a new driver file (ComputerGuessDriver.cpp) so that the user picks the

secret number and the computer tries to guess the number. Try to have the

computer use as few guesses as possible. What is a secret number that forces the

computer to take the maximum number of guesses? You will need to modify
