Prog #1: Magic Square Solution

$30.00

Description

Write a program in C to play the mind-reader game of a Russian Magic Square. Your interface will be text-driven and will not use graphics. For symbols, you will use letters of the alphabet.

Running your program will look something like what is shown below, where user input is shown in bold:

Program #1: Russian Magic Square

1. Choose any two-digit number in the table above (e.g. 73).
2. Subtract its two digits from itself (e.g. 73 - 7 - 3 = 63)
3. Find this new number (e.g. 63) and remember the letter next to it.
4. Now press the return key and I'll read your mind...

You selected the character: y

You need to know the following concepts in order to write this program:

How a Russian Magic Square Works (do some web research…); how to use some integrated development environment such as DevC++, Codeblocks, QtCreator or xcode; simple input and output; using variables; simple if statements; a while loop; generating a random number.

Notes:

  1. The Zyante review material for the first week will give you the components you need to do this program (variables, loops, input/output in C, random numbers)

  2. Make sure you read the syllabus regarding the grading criteria. Particularly on the first program, students tend to lose points for not documenting adequately and for not choosing meaningful variable names.

  3. Note that you must give both upper and lower case letters in your table. One way to do this is to check your random number. If it is even, generate an upper-case letter. If it is odd, generate a lower-case letter.

  4. Remember to include your TA’s NAME and your LAB DAY in the documentation header of your programs AS WELL AS in the output that appears on the screen.

  5. Do not be deceived. Future programs will be much more complex.

Grading Rubric

The 55 points for program execution will be allocated as follows:

5 points:  Displays header information with program name, author name, lab, date and system.
5 points:  Displays table, with items counting down from 99 down to 0
5 points:  Columns are lined up
5 points:  Table has both upper and lower-case values
5 points:  Special character value appears where it should be
10 points:  Program displays table, instructions, and then waits for the return key to be pressed before continuing, then shows answer.
10 points:  Special character changes each time program is run
10 points:  Table changes each time program is run

Turning In Your Program

The name of the program you will turn in should be prog1 followed by your netid and the .cpp file extension.  In other words, if your netid is reed then your program would be called prog1reed.cpp     Blackboard considers program source code as a threat and sometimes replaces random parts of it.  To avoid this you must also zip up the file you turn in.  To zip a file right-click on the .cpp file to be turned in (e.g. prog1reed.cpp) and select “Send To” and then select the “compress” menu option.  On a Mac simply right-click and then select the “compress” option.  The resulting file will then be called prog1reed.zip  .  Only turn in this single file, turning it in on Blackboard into the Assignment Program1: Magic Square.  Failing to follow these naming conventions and turning in a zip file will result in a 5 point deduction.  (Note that I am not requesting some compression, but specifically zip compression)  You may turn in multiple versions, but only the latest version will be graded.
