Which operator(s) in C have wrong precedence?

Question

In the \"Introduction\" section of K&R C (2E) there is this paragraph:

C, like any other language, has its blemishes. Some of the operators h

Answer 1

Yes, the situation discussed in the message you link to is the primary gripe with the precedence of operators in C.

Historically, C developed without &&. To perform a logical AND operation, people would use the bitwise AND, so a==b AND c==d would be expressed with a==b & c==d. To facilitate this, == had higher precedence than &. Although && was added to the language later, & was stuck with its precedence below ==.

In general, people might like to write expressions such as (x&y) == 1 much more often than x & (y==1). So it would be nicer if & had higher precedence than ==. Hence people are dissatisfied with this aspect of C operator precedence.

This applies generally to &, ^, and | having lower precedence than ==, !=, <, >, <=, and >=.
