I'm beginning to learn C and understand many of the fundamentals in isolation, but I struggle to apply them when building complete programs. Once multiple concepts—such as several functions, control flow, and data structures—are connected, I have trouble following the program's logic and figuring out how to design my own solution. I'm looking for a free, project-based learning path with progressively harder exercises, similar in spirit to a structured web-development curriculum. Resources can be websites or video courses, but I'd especially like something that helps me learn C through practical projects rather than separate, disconnected tutorials.

Rather than only looking for finished solutions, attempt a project yourself and document where you get stuck. Share the relevant code, explain what you expected it to do, describe what actually happened, and mention what you already tried. That process encourages you to reason through the problem and makes feedback much more useful. A practical progression could be small command-line utilities, file-handling programs, data-structure exercises, and eventually a larger project such as a simple shell, text editor, or networked application.
When a larger program feels confusing, map out its flow before coding. Write down the inputs, the expected outputs, and the individual tasks needed between them. Then turn those tasks into functions with clear responsibilities. For example, a small command-line program might have separate functions for displaying a menu, reading input, updating data, and printing results. This makes it easier to see how the concepts connect instead of facing the entire codebase at once.
A roadmap by itself probably won’t solve the logic problem. Start with very small programs and build them up gradually: a calculator, a menu-driven to-do list, a text file analyzer, or tic-tac-toe. The goal is to practice breaking a problem into tiny steps, writing one function at a time, and testing each piece before adding more. Getting stuck and debugging is a normal part of learning, not evidence that you need another tutorial.
That’s the part I struggle with most—the connection between the functions. I understand individual topics, but real programs feel overwhelming. I’ll try writing the program flow and responsibilities down before coding.
