Thread: Problem with Program

Hey guys I had to write a program for a C++ class im in, There is 3 different outputs to perform (two early exits) and both of those work great but running the problem all the way though i do not get the follow results. Any assitance would be appreciate because I am stumped.
Input:
Exemptions : 5
AGI : 258250
Status: 2

Output
Line 2 = 18250
Line 3 = 258250
Line 4 = 250200
Line 5 = 8050
Line 6 = 4
Line 7 = 0.08
Line 8 = 1460
Line 9 = 486.67
Line 10 = 17763.33

I think my problem is in my User Defined Fuction but I am fairly new to programming and to be honest am COMPLETELY lost

Is the value of three in danger of fluctuating?

You should probably make your constants const.

You're not assigning the result of line6() to anything.

Code:

line6 (filingStatus, lineFive, lineSix) ;    // current

lineSix = line6(filingStatus, lineFive, lineSix);    // should be

Thank you that worked as far as returning a value even close to what it is supposed to be but its only returning 3 and according to the assignment if it rounded up it should return 4

Acutally i just got it, but thank you MSH for your help i really appreciate it.

this program is not returning my insurance rate properly, not sure where i really messed up but any help would be appreciated
