I’ve long been under the impression that goto should never be used if possible. However, while perusing libavcodec (which is written in C) the other day, I was surprised to notice multiple uses of it. Is it ever advantageous to use goto in a language that supports loops and functions? If so, why? Please provide … Read more
A reddit thread brought up an apparently interesting question: Tail recursive functions can trivially be converted into iterative functions. Other ones, can be transformed by using an explicit stack.
