bool CWaypoint::less(CWaypoint const &wp_right)
{
bool result;
CWaypoint temp1;
(calculateDistance(temp1) > temp1.calculateDistance(wp_right)) ?
result = 1 : result = 0;
return result;
}
why don't I get an error even when I am not returning a bool type ?
An integer-to-boolean conversion takes place. From the C++ standard:
4.12 Boolean conversions [conv.bool]
A prvalue of arithmetic, unscoped enumeration, pointer, or pointer to member type can be converted to a prvalue of type bool. A zero value, null pointer value, or null member pointer value is converted to false; any other value is converted to true.
