It's not necessary to recalculate the "strlen(word)" on every loop comparison when "word" doesn't change inside the loop.
Here also the same code as in word2vec.c

There was a problem hiding this comment.
The compiler knows that, too, and will move the strlen call out of the loop: https://gcc.godbolt.org/z/Pnso2q
Making the change explicit is not necessarily a bad idea; but then, I would suggest having const unsigned long long str_len=strlen(word); in a line of its own.
