What to Learn Next

Look how far you've come!

You now know the core of the C language:

• printing and reading with printf and scanf,
• variables, types and maths,
• decisions with if and switch, and loops,
• functions and recursion,
• arrays, strings and 2D arrays,
• pointers, structs and dynamic memory,
• enums, macros, files and multi-file programs.

That is a real foundation. Many professional programmers started exactly here.

Where to go from here

• Practise. The C Labs on this site have lots more challenges at every level. Solving small problems is the fastest way to get better.
• Data structures. Use your pointer and struct skills to build linked lists, stacks and queues.
• C++. C++ is built on top of C and adds classes, strings and ready-made containers. Most of what you learned here works there too.
• Linux and systems. Linux is written in C. Learning Linux shows you where C really shines.
• Security. Understanding memory in C is the first step to understanding many security bugs, like buffer overflows.

Remember: Every expert was once a beginner who kept practising. Write a little C every day!
