Thread: URGENT! Menu driven & records handling

PHP Code:

-- Please help me out. I have spent 48hrs nonstop trying to get my this set of programs to work. I have to submit my project on 18-19 this NOV. 

-- Basically i want to create a list of menu driven screens allowing the user to navigate through them: allowing him to create/add, delete and seek and display list of members and films rented by a video club.

-- I have created the screens and a screen allowing member to be added to a file(memberz.dat) but can't work around to delete a record and list them.

-- Neither i can coordinate them to work all together. Plzzz help me. This course work will allow me to pass my whole diploma level.

--Have been borrowing bits and pieces from diff. programs. They do work. I also need to enter a current fee charged for hiring a film and calculate any outstanding fee.

I am confused and stucked no way i'll be able to complete. Just have to scroll up and down the screen for days. Well here is what i have done. I would be very grateful to all you ppl. Plzzzz help me out. i have had loads of sample code but can't get them working after modify. 

I am using Turbo C++ 3.1 to run them.

here are programs:

here's a couple tips:

1. Don't use a bunch of different colors in your post text, it's very annoying.
2. Don't make me horizontally scroll to read your post, equally annoying.
3. State specific problems you have, such as "This line doesn't compile", "I don't understand this piece of code", etc.

Nobody wants to see your homework code and requirements and just figure out the assingment for you.

4. If possible create a small example program that demonstrates your problem without having to post your entire program.

6. If your compiler is Turbo C++, post in the C++ forum.
