Selection menu with "Enter" key support

Hello,
I am working on a database project, which can store (initially) 10,000 marksheets with following capabilities
1) new entry
2) edit/modification of entry
3)delete entry
4) separate Departements ( BBA, BCS, M.Phil, Phd., etc.)
5) can store data on files ( initially, all data is stored in a single file)

now, i want to create a menu, in which i can use arrow keys to navigate through the menu and use Enter key fo selection.

can any body give any idea about, what should i use in it??

P.S: The project is only on C language.

Thanks.

Depending on your OS, you need a library like curses to handle the arrow keys.

Bye, Andreas

welll thanks for suggession, i made a 4 function calculator by using this theme,
but the problem is
1) the menu is at the corner and i want it to be in center or whrere i want.
2) the program is not correctly working in "abc.exe" file. it is showing ANSI codes.

plz tell me how to upload code here so you can chek it.

Code:

You operating system is Windows, right?

Your compiler is Turbo C, right?

Do you HAVE to use Turbo C for this, or can you update to a MUCH better IDE/compiler, that is free?

The reason I ask is Turbo C is a 16 bit program that won't run in Windows 7, natively. Also, it's very limited in the size of programs you can create, array sizes you can construct, etc.

May I suggest using either Microsoft's free C ide/compiler, Pelles C ide/compiler or Codeblocks IDE with Ming for Windows compiler? (I use Pelles C, and love it!).
