Class Point has two constructors: Point that assigns zeros to variables x and y, and Point int x, int y that assigns values x and y to variables this. Write the following counstructors: Circle - assume that default radius is 1 and center 0,0 Circle int radius - that assigns integer radius to this.

I am doing it, as you can see in my edit Post what errors you're getting and we'll be happy to take a look for you. I got you. You were doing fine in the Point class, but seem to get really confused in the Circle class. Ask if you need any more clarifications.
Show 1 more comment. Active Oldest Votes. The mistakes were mostly in your Circle class. I think you need a few clarifiations: The properties radius and center are already declared in the beginning of your class. To assign values to them, you need to do something like this.
In your constructor, you want to assign values to your properties. Your properties can be accessed by calling this. What you seem to be doing is assigning a value to a new variable called radius. Finally, you can't call c. Improve this answer. Your assignment asked for a demonstration of all four constructors. You can do that by yourself. Create four different circles, one using each constructor, and print them out.

This we believe is a better way of understanding a problem and makes use of the efficiency of time of the student. New orders are original solutions and precise to your writing instruction requirements.
Place a New Order using the button below. Your program should consist of a class, say romanType. An object of romanType should do the following: a. Store the number as a Roman numeral. Convert and store the number into decimal form. Print the number as a Roman numeral or decimal number as requested by the user. Write two separate functions? The decimal values of the Roman numerals are: me of type!. Any place in a decimal number, such as the is place, the 10s place, and so on, requires from zero to four Roman numerals.
The class dayType should store the day, such as Sunday for Sunday. The program should be able to perform the following operations on an object of type dayType: a. Set the day. Print the day. Return the day. Return the next day. Return the previous day. Calculate and return the day by adding certain days to the current day. For example, if the current day is Monday and we add 4 days, the day to be returned is Friday. Similarly, if today is Tuesday and we add 13 days, the day to be returned is Monday.
In Chapter 1, the class clockType was designed to implement the time of day in a program. Certain applications, in addition to hours, minutes, and seconds, might require you to store the time zone. Derive the class extClockType from the class clockType by adding a data member to store the time zone.
Also, write the definitions of the member functions and the constructors. Finally, write a test program to test your class. In this chapter, the class dateType was designed to implement the date in a program, but the member function setDate and the constructor do not check whether the date is valid before storing the date in the data members. Rewrite the definitions of the function setDate and the constructor so that the values for the month, day, and year are checked before storing the date into the data members.
Add a function member, isLeapYear, to check whether a year is a leap year. Moreover, write a test program to test your class. A poir Desigi plane. Evei class per cla ope. Date r are checked before r function inemb Moreover, write 3. Design a class, pointType, that can store and process a point in the x-y plane. You should then perform operations on the point, such as showing the point, setting the coordinates of the point, printing the coordinates of the point, returning the x-coordinate, and returning the y-coordinate.
Also, write a test program to test the various operations on the point. Every circle has a center and a radius. Given the radius, we can determine 4. Given the center, we can determine its position in the x-y plane. The center of a circle is a point in the x-y plane. Design a class, circleType, that can store the radius and center of the circle.
Because the center is a point in the x-y plane and you designed the class to capture the properties of a point in Programming Exercise 3, you must derive the class circleType from the class pointType. You should be able to perform the usual operations on a circle, such as setting the radius, printing the radius, calculating and printing the area and circumference, and carrying out the usual operations on the center. Every cylinder has a base and height, where the base is a circle. Design a class, cylinderType, that can capture the properties of a cylinder and perform the usual operations on a cylinder.
Derive this class from the class circleType designed in Programming Exercise 4. Some of the operations that can be performed on a cylinder are as follows: Calculate and print the volume, calculate and print the surface area, set the height, set the radius of the base, and set the center of the base. Redefine the class dateType so that it can perform the following operations on a date in addition to the operations already defined: a.
Set the month. Set the year. Return the month. Return the year. Test whether the year is a leap year. Return the number of clays in the month. For example, if the date is , the number of days to be returned is 31 because there are 31 days in March. Return the number of days passed in the year. For example, if the date is , the number of days passed in the year is
