C Tutor

C programming tutoring for university students. Pointers, memory management, systems programming, and more.

C is the foundation of systems programming and remains essential for understanding how computers actually work. It's challenging because there's no safety net—you manage memory directly, work close to the hardware, and debugging requires understanding what's happening at the machine level. I help students build that mental model.

Topics we cover

Common areas where students need help.

Pointers and pointer arithmetic
Memory allocation (malloc, free, realloc)
Segmentation faults and debugging
Structs and data structures
File I/O and system calls
Linked lists, trees, and graphs in C
Makefiles and compilation
Valgrind and memory leak detection

FAQ

Why is C so hard compared to Python?
C doesn't hide complexity from you. In Python, memory is managed automatically. In C, you're responsible for every allocation and deallocation. This makes C harder initially but gives you deeper understanding of how programs actually work.
How do I debug segmentation faults?
Segfaults usually mean you're accessing memory you shouldn't. I teach systematic debugging: using GDB to find where the crash occurs, Valgrind to detect memory issues, and developing the habit of checking pointers before dereferencing.
Is C still relevant in 2024?
Yes. Operating systems, embedded systems, databases, and game engines are written in C. Understanding C makes you a better programmer in any language because you understand what higher-level languages abstract away.
Can you help with university C assignments?
Yes. I regularly help with UNSW's COMP1511/COMP2521, UniMelb's COMP20003, UWA's CITS2002, and similar courses. I'll help you understand the concepts and debug your code without doing the work for you.
