Learning C

C is the language underneath operating systems, drivers, and firmware, and understanding C means understanding how hardware really works. This app starts from types and operators through pointers, dynamic allocation, and memory manipulation. The app gives special attention to pointers and manual memory management — the topics that cause the most confusion — with diagrams and step-by-step examples.

What you’ll study

• Types, variables, and operators
• Control flow and functions
• Arrays and strings
• Pointers and memory addresses
• Dynamic allocation (malloc/free)
• Structs and file I/O

How it works

You study in focused modules, reinforce with exercises, practice in the phone IDE, track progress, and can get a certificate. Premium without ads is available.

Who it’s for

• Computer engineering and embedded systems students
• Programmers who want to understand how memory works
• Beginners who want a solid low-level foundation

Open the app, pick a module, and practice a little each day.
