Here is a second one I am stuck on. This one is working correctly, but I didn't know how to go about doing a function for the output of line 9 so that put me into problem of not being able to figure out how to get line 10 to output the Lifetime Learning Credit.

I was supposed to do a function for line 9:

The function shall take two input arguments:
the line 7 amount and the line 8 amount.
o The function will test if line 7 is equal to or more than line 8, and then compute
the correct results for line 9.
o The function will return the floating point result.
o No other computations should be performed within this function.
Examples: Input arguments of line 7 = 15000 and line 8 = 10000 would return 1.0
Input arguments of line 7 = 12222 and line 8 = 20000 would return 0.6111

Line 10 is supposed to be:

Multiply line 4 by line 9 and enter result on line 10.
This is your Lifetime Learning Credit. Enter the line 10 results on Form 1040, line 49.

Many of us ignore any posts with URGENT or ASAP. They indicate to us posters that think their problems are more wothy of help than others, and, to us, there is no urgency at all.

But aside from that (don't do it again) you need to ask better questions. You ask:

I was supposed to do a function for line 9:

The function shall take two input arguments:
the line 7 amount and the line 8 amount.
o The function will test if line 7 is equal to or more than line 8, and then compute
the correct results for line 9.

Well, line 9 is const double CUTOFF1 = 10000;. There is no possible way to convert that into a function.

Remember, we don't know your project so you must explain what you really need in terms of the code you have, not the unspecified project directions

Line 10 is supposed to be:

Multiply line 4 by line 9 and enter result on line 10.

Line 4 is using namespace std; .

The function will test if line 7 is equal to or more than line 8, and then compute
the correct results for line 9. The function will return the floating point result.

How does it calculate ? What is the formula ?
