project[1]: howdy, c Solution

Project Goals


The goals of this project are to:

    1. Provide you an overview of core c programming concepts

    2. Introduce variables, assignment, choice, and iteration

    3. Explore c arithmetic and logical operators


Project Description


This project consists of three simple programs:


Program 1 (speed conversion):​

Write a program that converts measurements from miles per hour to meters per second.

This program should:

    • prompt a user to enter a speed in miles per hour, then

    • output the equivalent speed in meters per second.

For example the program should prompt:

Please enter a speed in miles per hour:

If the user enters 25, then the program should output:

25 mph is 11.176 m/s

Code for this program should be in a file named ​convert.c


Program 2 (compound interest):

Write a program that serves as a compound interest rate calculator. This program should:

    • prompt a user to enter a dollar amount (principal) and a percentage (annual interest rate), then

    • output the value of the principal, plus interest compounded annually each year for

20 years. For example, the program should prompt the user:

Please enter the amount of principal and interest percentage:

if the user entered: ​1000 5,​then the program should output:

    • $1050.00

2   $1102.50

3   $1157.62

4   $1215.51

5   $1276.28

6   $1340.10

7   $1407.10

8   $1477.46

9   $1551.33

    10 $1628.89

    11 $1710.34

    12 $1795.86

    13 $1885.65

    14 $1979.93

    15 $2078.93

    16 $2182.87

    17 $2292.02

    18 $2406.62

    19 $2526.95

    20 $2653.30

Constraints
    • You must use​ a while loop to​ calculate each year’s value.

Code for this program should be in a file named ​interest.c



Write a program that computes your percentage grade for cs135 given the percentage
weight for each portion of this cs135 class in the class syllabus​.​You must calculate the following:

    • project average (must prompt for the number of projects)

    • quiz average (must prompt for the number of quizzes)

    • exam average (must prompt for the number of midterms)

    • overall class average

So your program should read each grade (a number between 0.00 and 100.00) for each portion of the class in the following order

    1. projects

    2. midterms

    3. quizzes

    4. final project

    5. final exam

After reading these values from the terminal, your program should then compute and print the following:

    1. The average projects grade (not including the final project)

    2. The average of all the midterm and final grades

    3. The average of the quiz grades

    4. The final percentage grade

    5. Whether these scores qualify a student for cs202 (C (73) or better, as per the syllabus)

on the terminal. Here is sample output:

Average projects grade: 87.50

Average exam grade: 97.20

Average quiz grade: 92.45

Final grade: 92.45

You can take cs202

Constraints
    • You must use​ for loops to​ read in the multiple project, quiz, and midterm grades.

Code for this program should be in a file named ​grade.c

Challenge:​Deal with the case where you want to know your maximum possible percentage grade sometime during the semester and you have not been given all your projects and tests. In this case, reading a -1 for a project or test means that you have yet to receive a grade for this item. You compute the maximum possible percentage by assuming you obtained a 100.00 on this item.

Submission details


The project needs to be submitted before midnight, Thursday, 9/22/2015, 11:59:59pm.

To submit your project, you will have to save your scratch project file to an ECC machine using the Linux VM or the nomachine client:

    • create a directory called “project1”

    • put ALL of your code in that directory

    • save your description file into that directory
    • DO THIS ONCE: Install the submission script (don’t​ type the ‘>’ symbols)

        ◦ cd ~

        ◦ rm submit
        ◦ wget http://www​.cse.unr.edu/~newellz2/submit

        ◦ chmod +x ./submit

    • TO Submit:

        ◦ cd project1

        ◦ ~/submit


please use cs135 as the class name and project1 as the project name (no capitals).

The submission script copies all files in the current directory to our directory. You may submit as many times as you like before the deadline, we only keep the last submission.


Academic Honesty


Academic dishonesty is against university as well as the system community standards.

Academic dishonesty includes, but is not limited to, the following:

Plagiarism: defined as submitting the language, ideas, thoughts or work of another as one's own; or assisting in the act of plagiarism by allowing one's work to be used in this fashion.

Cheating: defined as (1) obtaining or providing unauthorized information during an examination through verbal, visual or unauthorized use of books, notes, text and other materials; (2) obtaining or providing information concerning all or part of an examination prior to that examination; (3) taking an examination for another student, or arranging for another person to take an exam in one's place; (4) altering or changing test answers after submittal for grading, grades after grades have been awarded, or other academic records once these are official.

Cheating, plagiarism or otherwise obtaining grades under false pretenses” constitute academic dishonesty according to the code of this university. Academic dishonesty will not be tolerated and penalties can include canceling a student’s enrollment without a grade, giving an F for the course, or for the assignment.
