This assignment exercises your ability to use loops, and provides more experience with asking the computer to generate a pseudo-random number.

Instructions

Your goal for this assignment is to exercise your knowledge of selection statements ( if / else ), looping constructs ( while and for ), the use of rand(), and File I/O. Your game must adhere to the following interaction example.

Hold onto your pants, we're about to play guess-the-numbah!
Enter the lowest possible number: 14

Enter the highest possible number: 15
High number must be at least 200 more than the low number.

Enter the highest possible number: 357

Pick a number between 14 and 357: 20
Too low! Not even close!

Pick a number between 14 and 357: 75
Too high!

Pick a number between 14 and 357: 1
Invalid guess.

Pick a number between 14 and 357: t
Please enter a number.

Pick a number between 14 and 357: 63
Too low! Oooh you're close!

Pick a number between 14 and 357: 64

That's right! You won the game in 4 tries.
Congratulations!  You've set a new high score breaking your old record of 11 tries!

You must first prompt the user to enter the low end of the integer number range. Then prompt the user to enter the high end of the integer number range. The high end must be at least MIN_RANGE more than the low end entered by the user. Your game must use a random integer number between LOW and HIGH, inclusively. You should only accept guesses that are within the range [LOW, HIGH], showing an error message otherwise. Your game must print "Too low!" or "Too high!" relative to the target number and the player's guess. Your game must print "Oooh you're close!" if the number guessed differs from the target by TOO_CLOSE_DIFFERENCE or less; and it must print "Not even close!" if the number guessed differs from the target by a value of TOO_HIGH_DIFFERENCE or more.

For example, if the target is 50, the player enters 10, the TOO_HIGH_DIFFERENCE is 25, and the TOO_CLOSE_DIFFERENCE is 10, then your program should print "Too low! Not even close!", but if the player enters 52, your program should print "Too high!" and "Oooh you're close!". When the correct number is guessed, your program must print "You won the game in N tries" where N is the number of valid guesses the player made.

At completion of the game, you'll need to check if the player set a new high score. We will use an external file to keep track of the current high score. If this is the first time they've played the game, then print a message similar to:

Congratulations on your first game!  The high score is 4 tries!

If they had played the game before and if they set a new high score, then print a message similar to:

Congratulations!  You've set a new high score breaking your old record of 11 tries!

If they had played the game before but they did not set a new high score, then print a message similar to:

Better luck next time.  The current high score is 11 tries.

Functional Requirements

Define the following constants
- TOO_CLOSE_DIFFERENCE (=5)
- TOO_HIGH_DIFFERENCE (=25)
- MIN_RANGE (=200)
Use these constants correctly. (By making these values constants, we can store them in one place in our program. If we change any of the values, then our program will operate under a new set of valid constraints. Changing these values could make the game easier or harder.)
We can no longer assume the user will follow instructions. Be sure to validate all inputs by ensuring that a number (not a character) was entered and the number is within the specified ranges.
Use an external file to store the current high score. You may determine the format of the file contents.

Grading Rubric

Your submission will be graded according to the following rubric.

36	Total Points

Submission

Always, always, ALWAYS update the header comments at the top of your main.cpp file. And if you ever get stuck, remember that there is LOTS of help available.

It is critical that you follow these steps when submitting homework. You can view these steps by watching the Windows / Mac video.

If you do not follow these instructions, your assignment will receive a major deduction. Why all the fuss? Because we have several hundred of these assignments to grade, and we use computer tools to automate as much of the process as possible. If you deviate from these instructions, our grading tools will not work.

Submission Instructions

Here are step-by-step instructions for submitting your homework properly:

File and folder names are extremely important in this process. Please double-check carefully, to ensure things are named correctly.
1. The top-level folder of your project must be named Set4
2. Inside Set4, create 4 sub-folders that are required for this Set. The name of each sub-folder is defined in that Set (e.g. L4A, L4B, L4C, and A4).
3. Copy your files into the subdirectories ofSet4 (steps 1-2), zip this Set4 folder (steps 3-4), and then submit the zipped file (steps 5-11) to Canvas.
4. For example, when you zip/submit Set4, there will be 4 sub-folders called L4A, L4B, L4C, and A4 inside the Set4 folder, and each of these sub-folders will have the associated files.
Using Windows Explorer (not to be confused with Internet Explorer), find the file named "main.cpp" located inside the folder for the particular lab or homework assignment you will submit.

STOP: Are you really sure you are viewing the correct assignment's folder?
Now, for A4, right click on the main.cpp to copy the file. Then, return to the Set4/A4folder and right click to paste the file. In other words, put a copy of your homework's main.cpp source code into the Set4/A4 folder.

Follow the same steps for L4A, to put a copy of your lab's main.cpp into the Set4/L4A folder. Repeat this process for Set4/L4B, Set4/L4C.

STOP: Are you sure your Set4 folder now has all your code to submit?
Now, right-click on the "Set4" folder.
1. In the pop-up menu that opens, move the mouse "Send to..." and expand the sub-menu.
2. In the sub-menu that opens, select "Compressed (zipped) folder".
STOP: Are you really sure you are zipping a Set4 folder with sub-folders that each contain a main.cpp file in it?
After the previous step, you should now see a "Set4.zip" file.
Now visit the Canvas page for this course and click the "Assignments" button in the sidebar.
Find Set4, click on it, find the "Submit Assignment" area, and then click the "Choose File" button.
Find the "Set4.zip" file created earlier and click the "Open" button.

STOP: Are you really sure you are selecting the right homework assignment? Are you double-sure?
WAIT! There's one more super-important step. Click on the blue "Submit Assignment" button to submit your homework.
No, really, make sure you click the "Submit Assignment" button to actually submit your homework. Clicking the "Choose File" button in the previous step kind of makes it feel like you're done, but you must click the Submit button as well! And you must allow the file time to upload before you turn off your computer!
Canvas should say "Submitted!". Click "Submission Details" and you can download the zip file you just submitted. In other words, verify you submitted what you think you submitted!

In summary, you must zip the "Set4" folder and only the "Set4" folder, this zip folder must have several sub-folders, you must name all these folders correctly, you must submit the correct zip file for this homework, and you must click the "Submit Assignment" button. Not doing these steps is like bringing your homework to class but forgetting to hand it in. No concessions will be made for incorrectly submitted work. If you incorrectly submit your homework, we will not be able to give you full credit. And that makes us unhappy.
