(1) Create a class Rectangle with attributes length and width, each of which defaults to 1. Provide member function that calculate and the area of the rectangle. Also, provide set and get functions for the length and width attributes. The set function should verify that length and width are each floating-point numbers larger than 0.0and less than 20.0

(2) Imagine a tollbooth at a bridge. Cars passing by the booth are expected to pay a 50 cent toll. Mostly they do, but sometimes a car goes by without paying. The tollbooth keeps track of the number of cars that have gone by, and of the total amount of money collected. Model this tollbooth with a class called tollBooth. The two data items are a type unsigned int to hold the total number of cars, and a type double to hold the total amount of money collected. A constructor initializes both of these to 0. A member function called payingCar() increments the car total and adds 0.50 to the cash total. Another function, called nopayCar(),increments the car total but adds nothing to the cash total. Finally, a member function called display() displays the two totals. Include a program to test this class. This program should allow the user to push one key to count a paying car, and another to count a nonpaying car. Pushing the Esc key should cause the program to print out the total cars and total cash and then exit.

(3) Create a class that includes a data member that holds a "serial number" for each object created from the class. That is, the first object created will be numbered 1, the second 2, and so on. To do this, you'll need another data member that records a count of how many objects have been created so far. (This member should apply to the class as a whole; not to individual objects. What keyword specifies this?) Then, as each object is created, its constructor can examine this count member variable to determine the appropriate serial number for the new object. Add a member function that permits an object to report its own serial number. Then write a main() program that creates three objects and queries each one about its serial number. They should respond I am object number 2,and so on.

(4) Create a class for time. There should be at least three functions
1. convertToSec(int hour, int min , int second, out intsecResult)
2. addSeconds(int,int)
3. convertToHMS(int)

User enters hours, minutes and seconds which will be converted into seconds by class function and stores result in secResult which is pass by reference variable. Then addSeconds function took two parameters, one is secResult which is the result of convertToSecand other is seconds, this function will add seconds and returns them as integer. After adding seconds then user call a function convertToHMS which has one parameter which took seconds as integer and convert back into Hours, Minutes and Seconds. After creating these functions use all of above functions in main function and show its execution one by one by assuming some values.

(5) Create a class called Employee that includes three pieces of information as data members, a name (type string), ID (type integer) and a monthly salary (type integer). Employee class should have a constructor that initializes the three data members. Provide a "setData" and a "getData" function for each data member. Write a test program that demonstrates class Employee's functionalities. Create two Employee objects and display each object's yearly salary.

(6) Generate code for the Given scenario.

(7) A cuboid is a three-dimensional shape having different measurements in each dimension say x,y, and z. Cuboids shapes are often used for boxes, cupboards,rooms,buildings, etc. So keeping in the mind the importance of Cuboids you have to implement the following functionalities.

(i) Declare a class Cuboids with its three data members of type float to have the measurements of the three dimensions.

(ii) Value should only be assigned to the data members when it is greater than 0 and lesser than 35.00

Write all the set functions for each data members to set values.

(iii) Implement default(sets all data members to 1),parameterized and copy constructor.

(iv) Provide a member function for taking the inputs for a particular object's data
