In a question about switch and goto, this answer used this code to avoid using a goto altogether:
switch(color)
case YELLOW:
if(AlsoHasCriteriaX)
case GREEN:
case RED:
case BLUE:
Paint();
else
default:
Print("Ugly color, no paint.");
How does this code work? I understand that cases automatically fall through, so I don't need it explained when color is YELLOW, but what about when color is GREEN? How does C++ handle else when it never encountered if. Would this code even compile, would it be a runtime error, or would it just ignore the else?
