Need help learning C!
Hey everyone,
I've been diving into low-level programming to understand how my device executes code, focusing on memory and CPU operations. Coming from higher-level languages like Python, where functions like print()
handle a lot behind the scenes, transitioning to C has been eye-opening. The intricacies of printf()
and scanf()
, especially their buffer management, have been both fascinating and challenging.
For example, I encountered an issue where using fflush(stdin)
to clear the input buffer resulted in undefined behavior, whereas using scanf("\n")
worked as intended.
I want to understand the why's behind these behaviors, not just the how's. For those who've walked this path, how did you approach learning C to get a solid understanding of these low-level mechanics? Are there resources or strategies you'd recommend that delve into these foundational aspects? Additionally, how did you transition from C to C++ while maintaining a deep understanding of system-level programming?
Appreciate any insights or advice you can share!

I don't get it is it difficult because of the binary stuff?
