IF ARRAY HAS LESS THAN 3 ELEMENTS
{
THROW ERROR
}

ELSE
{
sort the numbers in 2 arrays..
neg[]-> with negativ values in descending order
pos[]-> with positive values in descending order
->if there is a zero THEN
set a boolean value of a variabl ISZERO as TRUE
}


IF pos[] is empty
{
IF ISZERO==true THEN
// if there are only negativ values and a zero
RETURN ZERO;

ELSE
// all elements are -ve and no element is zero then
RETURN (neg[neg.length-1]*neg[neg.length-2]*neg[neg.length-3]);

}

IF (neg[] has zero or only 1 element) THEN
{
RETURN (pos[0]*pos[1]*pos[2]);
}
ELSE IF neg[] array has more than 1 value THEN
{
IF (neg[0]*neg[1]*pos[0]) > (pos[0]*pos[1]*pos[2]) THEN
RETURN (neg[0]*neg[1]*pos[0]);
ELSE
RETURN (pos[0]*pos[1]*pos[2]);

}

Question 1: Implement a base class Appointment and derived classes Onetime, Daily, Weekly, and Monthly. An appointment has a description (for example, “see the dentist”) and a date and time. Write a virtual function occurs_on(int year, int month, int day) that checks whether the appointment occurs on that date. For example, for a monthly appointment, you must check whether the day of the month matches. Then fill a vector of Appointment* with a mixture of appointments. Have the user enter a date and print out all appointments that happen on that date. *This Should Be Done IN C++
