It depends. I find it hard to read an expression with "&" and "&&" without parentheses. Anyway, I will admit that the above code is inconsistent in term of how parentheses are used. So I will change that.
Conditionals containing fragments like (a == b && c == d && ...) are much easier to read without any extra ().
The only problem with && is that when K&R added it to C they didn't change the priority of & to be higher than == (where it should be). At that time they could have changed all the existing code... Modern compilers do warn about (a == b & c).
