Relational operators are evaluated after arithmetic operators and before the assignment operator. == and != have slightly lower precedences than <, >, <= and >=.

What is the precedence of relational operators?

Relational operators have left to right associativity. Left to right associativity means that when two operators of same precedence are adjacent, the left most operator is evaluated first.

Do relational operators have higher precedence over logical operators?

The logical-AND operator ( && ) has higher precedence than the logical-OR operator ( || ), so q && r is grouped as an operand. Since the logical operators guarantee evaluation of operands from left to right, q && r is evaluated before s-- .
