5 modules -- beginner to advanced -- self-paced
Master C Programming
from Beginner to Advanced
Video lessons, downloadable notes, an in-browser coding playground, and quizzes that actually gate your progress -- ending in a certificate you earn, not one you're handed.
#include <stdio.h>
long factorial(int n) {
if (n <= 1) return 1;
return n * factorial(n - 1);
}
int main(void) {
printf("6! = %ld\n", factorial(6));
return 0;
}6! = 720

Why this track instead of another tab full of slides
Video-first modules
Every topic ships with a recorded walkthrough you can scrub, pause, and replay -- no talking-head fluff.
Notes you actually keep
Download plain-text lecture notes per module so you have something to grep through at 2am before an interview.
A playground, not a slideshow
Write C in the browser, hit Compile & Run, and see the flow end to end -- inputs, outputs, and all.
Quizzes that gate progress
Score 70% or better on each module quiz and the final test before a certificate becomes available.
People who finished it
“I'd failed the pointers unit twice in a college course. The arrays-and-pointers module here finally made *(arr + i) click -- the visual pointer-arithmetic walkthrough did it.”
“The playground is honest about what it can and cannot run, which I actually appreciated -- no fake green checkmarks. I still used it constantly to sketch logic before pasting into my real compiler.”
“Took the final test on a Sunday afternoon, scored 90%, and had a PDF certificate in my downloads folder thirty seconds later. Put it straight on LinkedIn.”
