Why does the for loop repeat in this recursion?

  • Yep

  • It's supposed to be a pyramid but not my code. It's an example of a recursive function from a CS50 lecture and I'm just trying to understand how the code works line by line.

  • Good point!

  • Ah ha! Yes, I did check the docs but I think I just glanced over that portion. Be more careful next time. Now that I took another look at the other ctype.h functions, they all return 1 or 0. I think I confused equivalent python built-in functions as those evaluated to true/false. The < is a less than sign but it seems it doesn't render correctly on Lemmy.

  • Sorry. It's in C. Updated post. Yes those are titles. I just included the relevant portions rather than the entire code.

    • Why does a control path not execute in this function?

  • Ah I see. I had a bad habit of using else if statements instead of else statements because I thought else if could be better in seeing the condition it's testing for so it was clearer. I get the logic is actually different now.
