riadbendraoua-byte/works.c ? reverse-engineered prompt

Build me a small C practice project with a couple of simple programs in it. I want one file that calculates Fibonacci numbers recursively, and another that does a basic student management style program, like storing a few student details and showing them back to the user. Keep it beginner friendly, with clear input and output, and make sure each program can be compiled and run easily from the command line.

Please clean up the code so it looks tidy and easy to understand, and add short comments where they help. If it makes sense, include a simple main menu so I can choose which program to run, or keep them as separate small programs if that is easier. Use only standard C and keep the scope small and practical. If you need to check anything current, look up the latest docs online.
