WHILE Loop Error / instreaming data file (w/functions)

dontmakeascene320 (11)
I have a working lab project with a loop error. Code posted in second post. Here's the requirements:

*
- program has to be able to handle file failure
- must loop (prefer to use a while loop here), read in the data, calculates values, etc. and then output the results.

*
The input data file includes

1. a 1 or a 0 indicating that there is a set of employee data following

2. the hourly rate of the employee

3. the humber of hours worked

4. the number of dependents

5. a 1 or a 0 indicating whether the employee is full time (1=full time).

Problem: At first I wouldn't loop back... so I moved the curly brace above the return0;

Now, however, it just runs forever.

Can anyone provide any feedback?


Thanks.
