C Foundation Programs 💻

This repository is a collection of beginner-friendly C programs that cover all the important foundation topics:

  • Operators & expressions
  • Conditions (if/else, switch)
  • Loops (while, for, do-while)
  • Functions (TSRS, TSRN, etc.)
  • Arrays & matrices
  • Strings
  • Patterns
  • Number theory (prime, HCF, LCM, Fibonacci, etc.)

It is perfect for B.Tech / BCA / Diploma students or anyone who wants to build strong C programming basics.

🎯 Goals of this Repo

  • Practise core C concepts with small, focused programs
  • Understand logic building step by step
  • Use this as a quick revision sheet before exams or interviews
  • See examples of clean, simple C code

📁 Structure & Naming Style

All programs are simple .c files kept in the root of the repo.

Most filenames follow this pattern:

a-prog-to-<what-the-program-does>-ass<assignment_no>.c
a-function-to-<what-the-function-does>-tsrs-ass<assignment_no>.c

📩 Contact

If you have doubts, suggestions, or want to discuss any program:

  • Open an Issue on this repository

  • Or connect with the repo owner on GitHub: @HEYKASHIF

Happy coding in C! 🎉
