Help with unhandled exception

[SurviBee]

Assignment was to take information about sales made, hours worked and number of dependents from a file, calculate the gross pay expected on one of two plans
Plan A 10% commission on sales, and 9.50 an hour with 1.5x overtime after 40 hrs
Plan B 30% commission

then we had to calculate all tax deductions for the higher paying plan and output these to both the screen and an output file.
I keep getting an unhandled exception error at my gross pay pointer planA inside the PickaPlan function.
Any suggestions or comments are greatly appreciated.

Here is the input file

1200.00 45 1
1200.00 40 3
1200.00 35 4
1875.50 35 3
1875.50 40 5
1875.50 45 2
2250.75 48 4
2250.75 40 3
2250.75 35 2

I experimented with your code and I think a problem might be that you are declaring, but possibly not setting aside memory for

float* planA;
float* planB;

When I put these two lines at the top of the function:

planA = new float;
planB = new float;

the program didn't crash. It went into an infinite loop, but it did not crash.
