Welcome to Level 2 of the C Programming course — where we move beyond basic syntax and start programming like real developers. In this level, you will strengthen your foundation with 2D arrays and take a deep dive into functions, including inline functions, passing arrays to functions, and mastering recursion through multiple real problems.

You’ll enter the most powerful part of C — Pointers — learning how they work, how they connect with arrays and functions, and how pointer arithmetic gives you full control over memory. You’ll also explore Dynamic Memory Allocation, allowing programs to grow at runtime.

Next, you’ll build real-world models using Structures, Nested Structures, Padding, and Unions, and then learn File Handling to store and retrieve data from files, including practical examples like log and CSV files.

Finally, you’ll understand the Preprocessor, mastering #define, #include, macros, and conditional compilation — essential for writing clean, reusable, and scalable C programs.

By the end of Level 2, you will confidently write modular, memory-aware, real-world C applications — and be fully prepared for Advanced C in Level 3.
