The problem is
A super market has 100000 clients. Each client has a codename (ex. ABC123456789 or DE5429GH139R). Each client earns points for every visit to the Super Market depending on the money he spends. we want to know
-How many times has the client visited the Super Market
-How many points does he have.
-The 10 best clients(according to the points)
We also have 2 files as an input.
1)The first file is the connection between points->money spent on each visit
2)The second file is the codename of each client and the money he spent on each visit.
My program must have this menu
1. Insert Points File
2. Insert Shopping File
3. Best Clients
4. Client's Data
ANY IDEA HOW TO DO IT IN ORDER TO PASS THE LESSON..PLZZZ
