Assignment Questions from Exercise:6

[.BZU.]

Hello friends.. Madam sidra nay yeh question karnay ki di ay thay..

Question 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 toll Booth. 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. Make appropriate member functions const.
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 [Escape] key should cause the program to print out the total cars and total cash and then exit.


Question 5.: Start with the date structure in Exercise 5 in Chapter 4 and transform it into a date class. Its member data should consist of three ints: month, day, and year. It should also have two member functions: getdate(), which allows the user to enter a date in 12/31/97 format, and showdate(), which displays the date.


Question 6.: Extend the employee class of Exercise 4 to include a date class (see Exercise 5) and an etype enum (see Exercise 6 in Chapter 4). An object of the date class should be used to hold the date of first employment; that is, the date when the employee was hired. The etype variable should hold the employee’s type: laborer, secretary, manager, and so on. These two items will be private member data in the employee declaration, just like the employee number and salary. You’ll need to extend the getemploy() and putemploy() functions to obtain this new information from the user and display it. These functions will probably need switch statements to handle the etype variable. Write a main() program that allows the user to enter data for three employee variables, which then displays this data.
