This document contains the source code for a student record management system written in C for the Turbo C compiler. It defines structures to store student records and functions to add, list, delete records from a binary file. The main() function displays a menu to call these functions, including options to add, list, delete records or quit the program. Validation is included to check for invalid user input.
