——————————————
However, I’m trying to change the parameters of my printExceededDays() method to recevie the arrays:double[] breakfast, double[] lunch, double[] dinner just as how they are in the other methods. When I try to do so, it won’t print “Days with more calories than needed: “
Please help! I need to fix this ASAP. Thanks in advance
