Now this is a helpful explanation. Thank you!
Operator precedence doesn't mean "evaluates before everything else",
it means "in case of doubt, follow specified order".
Let's say you have the expression without parenthesis "A = B || C".
There's a doubt as long as we don't know the precedence order between
= and ||.
Now "(A = B) || C". Since we know that () takes precedence over ||, we
know that the expression is a || with two sides, A = B and C.
And "A = (B || C)". Since we know that () takes precedence over =, we
know that the expression is a = with left-hand A and right-hand B ||
C.
Now "A || B = C". Let's say we don't know the precedence between ||
and =. Putting parenthesis "A || (B = C)", we know that we have a ||
with two sides, A and B = C. But || is still evaluated from left to
right! On the contrary, (A || B) = C is invalid (wrong lef-hand side
for assignment operator).
Simply put, precedence has nothing to do with order of evaluation.
