Project 1

Due

Project 1 is worth 100 points and due at 11:59pm, Wednesday, 25 Feb

Requirements

Create a file named 6789prj1.c, using the editor of your choice. (Of course this assumes that the last four of your SSN is 6789, if not, use the last four of your SSN.)

This program is to calculate the monthly payment of a loan. You will ask the user from the amount of the loan and the interest rate of the loan. You are to calculate the the simple interest, add it to the amount of the loan and computer the monthly payment. You are to inform the user of the total amount to be repaid and the amount of the monthly payment. Note: The loan must be paid off in 12 months!

Compiling

Compile the program with the following command: If you got an error and you probably did, simply go back into the editor and fix it. Then recompile, continuing until you get no warnings or errors.

Executing

Execute the program with the following command: ./a.out If everything worked correctly, you should get the messages giving the total surface area and the volume.

One Sample Output

burt[119]: a.out
Loan Calculator

burt[120]:

Notice that the UNIX prompt must be on the next line!

Turning in your homework

Once you have everything absolutely correct, you must use Blackboard to submit the project to the TA for grading. Do not email it to the instructor because you will lose points for not following instructions!

When submitting the assignment, I only want the file 6789prj1.c. Please make the title and the file name the same when you submit it! If you submit a file name 6789prj1.c, the way we save the material delete everything but the last file with than name. Therefore, your file will be lost and we will give you a zero!!!! Use the last four of your SSN, not 6789!!!

Grading

This project will be grade using the following scale:

Documentation 25 points
Correct Results25 points
Correct Sytle25 points
Other25 points

You will lose 5 points if you do not name the file correctly.
You will lose 5 points if you email the project instead of submitting it via Blackboard.
You will lose 5 points if the prompt is not on the next line.
