I'm working on a command-line interface (CLI) application in C and facing a dilemma. While I know that using a hashmap could be more efficient for handling commands, I'm really struggling to understand how to implement one, and I've spent hours on it without much progress. On the other hand, I could stick with if-else statements, which would allow me to move forward faster. I get that there's a saying about optimization being problematic, but I also understand that some optimization can be necessary. What are your thoughts on this? How do you balance implementing efficient algorithms with keeping your project progressing without getting stuck on understanding complex structures?

I usually recommend getting a basic, solid algorithm working first, and then go back to optimize later if you need to. Start simple and benchmark to see where your application really needs improvement.
When looking for improved velocity, consider checking online resources to see if someone has tackled similar issues already. A quick search for parsing command line arguments in C could offer some straightforward options without the hassle of implementing your own hashmap.
If you're struggling with the hashmap setup, you might find that using function pointers in a command struct array gives you a cleaner and more organized solution compared to a long chain of if-else statements without the added complexity of a hashmap. Plus, platforms like runnable can help you test small implementations quickly before adding them to your main project.
That's a smart move! It makes sense to prototype first before fully integrating. It saves you time in the long run.
