precedence of () is not greater than &&

Question

In the following code,

int main() {
    int a =1, b = 2, c = 3;
    if(((a++) == 5) && ((b++) == 5) && ((c++) == 5)) {
        cout<<"inside if"<< endl; // prints !!!Hello World!!!
    }
    cout<<a<<b<<c<<endl;
    return 0;
}

all increment operation should be done before doing logical operation. But execution skips increment b and c. Why logical && precede over ()? By the way, result of this code is 223.

Answer 1

Because of short circuiting: when the left hand side of && is false, the right-hand side is not evaluated. The precedence, on the other hand, is the way you think it should be (and, as AnT says, it's unrelated to the behavior you're seeing): () has precedence over &&.

(Similarly, when the left hand side of || is true, the right-hand side is not evaluated.)
