{
??? int distance= 12 , price=2.3, Time =9||18 , n=2 ;
??? float total;
??? {
??? if(Time < 5||(Time>=23&&Time<24))
???? {
??????? if(distance<=3)
??????? total = 13;
??????? else
??????? total =( distance - 3 )*price*1.2 + 13;
???? }
??? else
???? {
??????? if(distance <= 3)
??????? total = 13;
??????? else
??????? total =(distance - 3)*price + 13;
???? }
