C Advanced
Dive deeper into C with advanced concepts including structures, preprocessor directives, file operations, and memory management.

Join the AI Workshop to learn more about AI and how it can be applied to web development. Next cohort February 1st, 2026

The AI-first Web Development BOOTCAMP cohort starts February 24th, 2026. 10 weeks of intensive training and hands-on projects.


Once you understand C basics, there’s a wealth of powerful features that let you write more sophisticated programs. Advanced C concepts give you fine-grained control over memory and program structure.

In this unit, you’ll dive deeper into C programming. We’ll cover structures for organizing related data, preprocessor directives for compile-time operations, file operations for reading and writing data, and memory management techniques including dynamic allocation and pointers.

These advanced concepts are essential for writing efficient, professional-grade C programs and will deepen your understanding of how software interacts with hardware.
