Question

C++ programming am inventory system:

The software needs to do the following:

-Load the inventory from and save the inventory to a file.

-Keep track of bolts at 1/8" diameter intervals from 1/4" to 1" and lengths at 1" intervals from 1" to 6"

-Keep track of nuts at the same diameter intervals and range as bolt diameters.

-Be able to add and remove nuts and bolts to and from the system during runtime

Sample Menus:

Weclome to NaBISCo!!!

1. View bolt Inventory
2. View nut inventory
3. Add nuts/bolts to inventory
4. Remove nuts/bolts from inventory
5. Quit

(N)uts or (B)olts: N

Please pick a diameter:
1. 1/4"
2. 3/8"
3. 1/2"
4. 5/8"
5. 3/4"
6. 7/8"
7. 1"
Choice: 3

What is the length (1 to 6): 5

There are 20 Nuts of that type in the system.
How many do you wish to add: 30
