Thread: How can I improve/shorten my C code?

Perhaps I'm mistaken, but it looks to me like goto is indeed an ASM instruction. I was always told to avoid goto in C because it was too "Assembly-ish".

It's just a branch. Writing in assembly the mnemonic has never (as far as I know) been "goto"; the example you give is a "C'ificiation"; it'll compile to an ASM branch instruction (which, yeah, are GOTOs but they're not called that in ASM)

You understand that any comparison in C only results in 1 or 0 yes?
You understand that bitwise OR just mangles the bits of 2 integers together (of which booleans are a part of) yes?
Then you should easily understand what the code is doing just by looking at it,
