Augment the time class referred to in Q2 to include overloaded increment (++) and decrement (--) operators that operate in both prefix and postfix notation and return values. Add statements to main() to test these operators.

Modify the time class from Q 2 so that instead of a function add_time() it uses the overloaded + operator to add two times. Write a program to test this class.

Create a class Int based on Q 1 . Overload four integer arithmetic operators (+, -, *, and /) so that they operate on objects of type Int. If the result of any such arithmetic operation exceeds the normal range of ints (in a 32-bit environment)— from 2,147,483,648 to –2,147,483,647—have the operator print a warning and terminate the program. Such a data type might be useful where mistakes caused by arithmetic overflow are unacceptable. Hint: To facilitate checking for overflow, perform the calculations using type long double. Write a program to test this class.

Question 3:
Create a class called employee that contains a name (an object of class string) and an employee number (type long). Include a member function called getdata() to get data from the user for insertion into the object, and another function called putdata() to display the data. Assume the name has no embedded blanks. Write a main() program to exercise this class. It should create an array of type employee, and then invite the user to input data for up to 100 employees. Finally, it should print out the data for all the employees.

Create a class called time that has separate int member data for hours, minutes, and seconds. One constructor should initialize this data to 0, and another should initialize it to fixed values. Another member function should display it, in 11:59:59 format. The final member function should add two objects of type time passed as arguments. A main() program should create two initialized time objects (should they be const?) and one that isn’t initialized. Then it should add the two initialized values together, leaving the result in the third time variable. Finally it should display the value of this third variable. Make appropriate member functions const.

Create a class that imitates part of the functionality of the basic data type int. Call the
class Int (note different capitalization). The only data in this class is an int variable.
Include member functions to initialize an Int to 0, to initialize it to an int value, to display
it (it looks just like an int), and to add two Int values.
Write a program that exercises this class by creating one uninitialized and two initialized
Int values, adding the two initialized values

3.1 Design algorithms for following using C#

Function 1: Rent calculation.
Return the total rent_value when vehicle_no, rented_date, return_date, with_driver parameters are sent in. with_driver parameter is set to true or false depending whether the vehicle is rented with or without driver.

Function 2: Day tour - hire calculation.
Calculate total hire_value when vehicle_no, package_type, start_time, end_time, start_km_reading, end_km_reading parameters are sent in. Should return base_hire_charge, waiting_charge and extra_km_charge as output parameters.

Function 3: Long tour - hire calculation.
Calculate total hire_value when vehicle_no, package_type, start_date, end_date, start_km_reading, end_km_reading parameters are sent in. Should return base_hire_charge, overnight_stay_charge and extra_km_charge as output parameters.

Is there more programs like these? This program was very useful and learned a lot from it.
