Let me introduce myself: my name is Monica, and I am taking my first computer science class.
The assignment my teacher wants us to complete: We're editing one of our previous programs that chooses, out of two possible payment plans, which plan is better, and then calculates a "bicycle salesperson's weekly salary", and outputs it to the screen. In the original program the user inputed the values (amount of hours worked, total weekly sales, and number of dependents). We're supposed to edit this program by having the computer retrieve the values from an input file, which is supposed to have a few lines of values. To make sure the program reads and calculates all possible sets of values, we have to put in a while loop. The information is supposed to output to a file as well.
My problem: For some reason the last line in the input file is outputted twice.
What my input file looks like:
CODE
40 1200 4
30 1200 0
What my output file looks like:
CODE
Gross Health Social State Federal Union Net
Pay Insurance Security Income Tax Income Tax Dues Pay
----- ---------- -------- ---------- ---------- ----- ---
450.00 10.00 27.00 22.50 63.00 6.00 321.50
Gross Health Social State Federal Union Net
Pay Insurance Security Income Tax Income Tax Dues Pay
----- ---------- -------- ---------- ---------- ----- ---
333.00 10.00 19.98 16.65 46.62 6.00 233.75
Gross Health Social State Federal Union Net
Pay Insurance Security Income Tax Income Tax Dues Pay
----- ---------- -------- ---------- ---------- ----- ---
330.00 10.00 19.80 16.50 46.20 6.00 231.50
What my code looks like now:
