Learn C Programming in Tamil – Step-by-Step Visual Course
Full free C course for beginners: clear English code + simple Tamil explanation, diagrams and real technician-style examples. This single page neatly arranges all the lessons in order so you can learn C language step-by-step like a complete website course.
Course overview
This C course is built like a proper learn-website curriculum. You can read each lesson as a standalone blog post, or follow the sequence below like a full structured course. Whenever new topics are added (files, dynamic memory, structures, etc.), they will appear in the same list.
No prior coding required
We start from “What is programming?” and gradually move into loops, arrays and pointers – always with examples and screenshots.
Code in English, explanation in Tamil
Source code, keywords and syntax stay in English, but every concept is explained in simple Tamil with real-life analogies.
Practical & technician-style examples
Marks, bills, meter readings, menu systems, mini tools – examples are chosen for electronics, electrical and computer technicians.
New lessons can be added easily
Below syllabus is just an HTML list – future posts can be plugged in quickly without changing the layout or design.
C Course syllabus – lesson by lesson
Follow this order if you're starting from zero. You can also jump directly to arrays, pointers or other topics if you're revising.

Coming soon – next topics in this C course
As we keep teaching C for technicians, new lessons will be added below. Bookmark this page and check back whenever you see an update on Tamil Technicians YouTube or social media.
Planned future lessons (draft idea):
- Structures in C – real-world records (students, devices, bills).
- File handling – storing data in text files and simple log systems.
- Dynamic memory –
malloc,free(optional advanced topic). - Mini-projects – putting multiple C concepts together for technicians.
