operations on records into files without DB
hi i want a programe that how to Write a small record management application for a school. Tasks will be Add Record, Edit Record, Delete Record, List Records. Each Record contains: Name(max 100 char), Age, Notes(No Maximum Limit). No database should be used. All data must be stored in one or two files. Listing records should print the names of the users in alphabetical order. And the important thing is, total file should not be re-written for every add/delete operation.
