This document contains code for a zoo management system (ZMS) written in C programming language. The code displays a main menu with options to manage animal and bird records. It allows the user to add, display, modify and delete animal/bird records stored in a binary file by their cell ID. Functions include validating unique IDs, input validation, searching/updating records, and file handling operations.
