KhilarajRegmi/Hospital-Management-using-C ? reverse-engineered prompt

Build me a simple hospital management system in C for a console app.

I want it to feel like a clean university project, with a menu driven flow and colored terminal output using ANSI colors. It should let me add, view, search, update, and delete basic records like patients, doctors, and appointments, and keep the data organized inside the program in a way that’s easy to use from the terminal.

Please make the interaction clear and friendly, with prompts that guide the user through each step, input validation where it makes sense, and a main menu that loops until the user chooses to exit. If needed, keep the code in one or two C files and make it easy to compile and run on a normal C compiler.
