Project 2 Program Design

Project 2 Program Design
Problem 1 - Dice (50 points)
In this program, you will build upon your program for project 1, problem #1 to allow multiple
rounds of the game. In average, player, who won most of the rounds, is the winner of the
game. In case if two players won the same number of rounds, the result of the game is draw.
Example input/output:
Input:
Enter the number of rounds: 3
Output:
Round 1: Player 1’s number is 6, Player 2’s number is 5.
Round 2: Player 1’s number is 4, Player 2’s number is 6.
Round 3: Player 1’s number is 4, Player 2’s number is 4.
It’s a draw!
1. Name your program project2_dice.c
2. The user enters the number of rounds for the game.
3. Use a for loop for counting rounds of the game.
Problem 2 – Characters (50 points)
In this program, you will calculate the result of an arithmetic operation of two single digit
positive integers. The program allows add, subtract, and multiply two single digit positive
integers by entering either +, -, * between the integers.
Example input/output #1:
 Enter input: 7 – 3
Output: 4
Example input/output #2:
 Enter input: 7 * 3
Output: 21
1) Name the program project2_arithmetic.c
2) Use getchar() function to read in the input. Do not use scanf.
3) There might be any number (1 or more) of white space(s) before the first integer,
between the integer and the operator in the input, or after the second integer.
4) The user input ends with the user pressing the enter key (a new line character).
5) The input format is exactly in the format of: integer1 operator interger2
6) Use switch statement to process the operator and the math.
7) If the operator entered is not one of the acceptable operators, display an error message
as the result.
Other requirements and submission:
1. Compile on student cluster (sc.rc.usf.edu):
gcc –Wall project2_dice.c
gcc –Wall project2_arithmetic.c
2. Test your program with the shell script on the student cluster:
chmod +x try_project2_arithmetic
./try_project2_arithmetic
3. Download the programs from student cluster and submit it on Canvas>Assignments.
Grading:
Total points: 100
1. A program that does not compile will result in a zero.
2. Runtime error and compilation warning 5%
3. Commenting and style 15%
4. Functionality requirement 80%
Programming Style Guidelines
The major purpose of programming style guidelines is to make programs easy to read and
understand. Good programming style helps make it possible for a person knowledgeable in the
application area to quickly read a program and understand how it works.
1. Your program should begin with a comment that briefly summarizes what it does. This
comment should also include your name.
2. In most cases, a function should have a brief comment above its definition describing
what it does. Other than that, comments should be written only needed in order for a
reader to understand what is happening.
3. Variable names and function names should be sufficiently descriptive that a
knowledgeable reader can easily understand what the variable means and what the
function does. If this is not possible, comments should be added to make the meaning
clear.
4. Use consistent indentation to emphasize block structure.
5. Full line comments inside function bodies should conform to the indentation of the code
where they appear.
6. Macro definitions (#define) should be used for defining symbolic names for numeric
constants. For example: #define PI 3.141592
7. Use names of moderate length for variables. Most names should be between 2 and 12
letters long.
8. Use either underscores or capitalization for compound names for variable: tot_vol,
total_volumn, or totalVolumn.
