CSCI 230 Assignment 05 Due: 10/12/06 (Thr)
Fall-2006 (100 pts)
Sinking Funds & Monthly Payments
Part I
(40 points)
Step 1. From the course web page (http://www.cs.niu.edu/~sjchung),
copy Prog05a.for and Prog05a.sjc into your f drive.
And, get printed copies of both files.
Step 2. Compile & link/edit your Prog05a.for to get Prog05a.obj and Prog05a.exe.
Step 3. Run your Prog05a.exe by:
h:\>Prog05a.exe > Prog05a.out
Your Prog05a.out should compare correctly to Prog05a.sjc.
Step 4. Study Prog05a.for and Prog05a.out.
Understanding them will help you do the problems
on Page 2 of this Assignment and write Prog05b.for.
Step 5. Complete the problems on Page 2 of this assignment.
Part II
(60 points)
Write a FORTRAN program that will prompt the user to enter Loan Amount (A),
Annual Rate (R) of interest, and Number (N) of years to finance the loan,
then compute the monthly payment (P) for the given A, R, and N.
In addition, your program will compute the amounts of interest, principles, and
balance for each month and for each year. The output by your program must display
the amounts for each month of the first year, followed by the annual reports.
Step 1. From the course web page (http://www.cs.niu.edu/~sjchung),
copy Prog05b.in and Prog05b.sjc into your H drive.
And, get printed copies of both files.
In case you need help, there is Prog05b.ref that you can use.
Step 2. Name your source program as Prog05b.for, and complete it.
Your Prog05b.for must be well structured, and must demonstrate
your knowledge on the use of FUNCTION and SUBROUTINE subprograms.
As always, your source program (Prog05b.for) must be well documented.
Step 3. Compile & link/edit your Prog05b.for to get Prog05b.obj and Prog05b.exe.
Step 4. Run your Prog05b.exe by: f:\>Prog05b < Prog05b.in | more
(to see the next page of the output, press the <Enter> key.)
Step 5. If the output shown on the screen (monitor) looks correct,
save the output as Prog05b.out by:
f:\>Prog05b < Prog05b.in > Prog05b.out
Your Prog05b.out should compare correctly to Prog05b.sjc.
