Functions in C exercises are where pass by value and pass by reference stop being abstract concepts and become tools you apply automatically. You’ve seen the theory and built three complete programs. Now it’s time to solve challenges on your own — finding the second maximum, deleting an element by position, and merging two sorted…
In the previous article we covered C functions theory. Now it’s time to write real programs. In this article we build three programs from scratch in gedit and compile them with gcc in Fedora — array search, transformations by reference and a statistics calculator. Each one puts pass by value and pass by reference to…
Functions in C work with the same concept as in Python — a named block of code you can reuse — but the syntax is stricter and the way data moves in and out is fundamentally different. In Python you never had to think about whether a function could modify the original variable. In C…
Pointers in C exercises are where the mental model becomes instinct. You’ve seen the theory and built four complete programs. Now it’s time to solve challenges on your own in Fedora — copying arrays with pointers, counting and replacing elements, and a final challenge that implements a basic dynamic data structure. Set up your workspace:…
In the previous article we built the mental model for pointers in C. Now it’s time to write real programs and see them doing useful work. In this article we build four programs from scratch in gedit and compile them with gcc in Fedora — each one uses pointers in a situation where they’re the…
Pointers in C are the topic that intimidates most students before they’ve even seen them — and then surprises them with how logical they actually are once the mental model clicks. Python hides memory management completely. C exposes it directly. That’s not a flaw — it’s the feature that makes C both powerful and educational….
Loops in C exercises are where for, while and do…while stop feeling like abstract concepts and become tools you reach for naturally. You’ve seen the theory and built three complete programs. Now it’s time to solve challenges on your own in Fedora — including Rock Paper Scissors, a number base converter, prime numbers and a…
In the previous article we covered C loops theory. Now it’s time to write real programs. In this article we build three programs from scratch using gedit and gcc in Fedora — a number guessing game, a data validator and a series calculator. Each one uses the loop that genuinely makes the most sense for…
Loops in C for, while and do…while work with exactly the same logic as Python — the concept of repeating a block of code is identical. What changes is the syntax and one important addition: the do…while loop that Python doesn’t have. If you understood loops in Python, you’re 80% of the way there. This…
Conditionals in C exercises are where the syntax stops feeling foreign. You’ve seen the theory and built three complete programs. Now it’s time to solve challenges on your own in Fedora — including a triangle classifier, a login system with attempts, and a final challenge that mixes everything. Set up your workspace: As always: try…
