    printf("Hello world\n");
    return 0;

From here the real work begins: variables, conditions, loops, functions, and memory management. It is not just a symbolic exercise. It is the first step into a language that teaches precision.

This blog is where I want to collect exactly that kind of material: solid foundations, practical examples, and a technical style that still stays readable.
