There's no such thing as priority, and neither precedence nor associativity define the order in which stuff is evaluated. They determine what is an operand of what operator.

apple && (banana || cherry) apple: LHS operand of && banana || cherry: RHS operand of && banana: LHS operand of || cherry: LHS operand of || (apple && banana) || cherry apple && banana: LHS operand of || apple: LHS operand of && banana: RHS operand of && cherry: RHS operand of ||

Operand evaluation order is what controls the order in which stuff is evaluated.

In order to provide short-circuiting, && evaluates its LHS operand before its RHS. Same goes for ||.

Given

apple && (banana || cherry) apple: LHS operand of && banana || cherry: RHS operand of && banana: LHS operand of || cherry: LHS operand of ||

apple must be evaluated before banana || cherry
banana must be evaluated before cherry

So we get:

  1. apple
  2. banana
  3. cherry
  4. ||
  5. &&

Given

(apple && banana) || cherry apple && banana: LHS operand of || apple: LHS operand of && banana: RHS operand of && cherry: RHS operand of ||

apple && banana must be evaluated before cherry
apple must be evaluated before banana

So we get:

  1. apple
  2. banana
  3. &&
  4. cherry
  5. ||
