Question

If I have a C string that contains *’s and I want to find the position of the 3 star in this string. What is the best/ more efficient way to do it other than going through a loop and checking char by char?

Thanks

You probably want to do the searching with strchr. Since you want the third instance of the character, you’ll still execute that in a loop.

Whether this will actually be more efficient than writing a loop on your own may be open to some question, but it probably won’t be any slower, and the intent will be more clear to anybody reading the code.
