Structures, Reading from file, set precision.

[acmarshall]

Hello all I need a little help finishing my assignment.

I am given a text file that contains information about vehicles in an auto dealership.
The vehicle records consist of the following fields:
VIN, Make, Model, Year, Color, Date of purchase, Cost, Date of Sale, Sale Price and Revenue.

The text file contains one vehicle record per each line. I need to write a program to do the following:

1. Reads the input file one line at a time and stores the appropriate data into the structure data fields in your program.
2. Computes and sets revenue made on each vehicle if it is sold.
3. Displays every vehicle record on a separate line.
4. Computes and displays number of vehicles with a year newer than 2000.
5. Computes and displays total revenue made on all sold vehicles.
6. Computes and displays number of vehicles costing less than $5000.
7. Computes and displays number of vehicles with a black color.
8. Computes and displays number of vehicles of Toyota make and red color.

It does numbers 1, 2, and 3 fine, but it messes up on the rest. I also need help formatting it using the set width so my output looks a lot my organized.

This is a copy of my input file:
