C++ "OR" operator

can this be done somehow? 

if((a || b) == 0) return 1;
return 0;

so its like...if a OR b equals zero, then...but it is not working for me. my real code is:

bool Circle2::contains(Line2 l) {
    if((p1.distanceFrom(l.p1) || p1.distanceFrom(l.p2)) <= r) {
        return 1;
    }
    return 0;
}
Solution

  • You need to write the full expression:

    (a==0)||(b==0)

    And in the second code:

    if((p1.distanceFrom(l.p1)<= r) || (p1.distanceFrom(l.p2)<=r) )
    return 1;

    If you do ((a || b) == 0) this means "Is the logical or of a and b equal to 0. And that's not what you want here.

    And as a side note: the if (BooleanExpression)return true; else return false pattern can be shortened to return BooleanExpression;
