Use the same UML as below and make extensions as necessary

You will follow the steps below which are exactly the same. So you can build on the code that you have already created. However, after you display the count using the getCount() method and vector size method, you will practice the vector erase and insert methods to erase and insert Circle objects. The instructions denoted by -> are what you will work on.You will also create a simple, basic destructor for the Circle class.

 Circle -int x //x coord of the center -int y // y coord of the center -int radius -static int count // static variable to keep count of number of circles created + Circle() //default constructor that sets origin to (0,0) and radius to 1 +Circle(int x, int y, int radius) // regular constructor +getX(): int +getY(): int +getRadius(): int +setX(int newX: void +setY(int newY): void +setRadius(int newRadius):void +getArea(): double // returns the area using formula pi*r^2 +getCircumference // returns the circumference using the formula 2*pi*r +toString(): String // return the circle as a string in the form (x,y) : radius +getDistance(Circle other): double // *** returns the distance between the center of this circle and the other circle +moveTo(int newX,int newY):void // *** move the center of the circle to the new coordinates +intersects(Circle other): bool //*** returns true if the center of the other circle lies inside this circle else returns false +resize(double scale):void// ***multiply the radius by the scale +resize(int scale):Circle // ***returns a new Circle with the same center as this circle but radius multiplied by scale +getCount():int //returns the number of circles created //note that the resize function is an overloaded function. The definitions have different signatures

A. Extend the driver class to do the following:

1. Declare a vector of circles
2. Call a function with signature inputData(vector
3. Use istringstream to create an input string stream called instream. Initialize it with each string that is read from the data file using the getline method.
4. Read the coordinates for the center and the radius from instream to create the circles
5. Include a try catch statement to take care of the exception that would occur if there was a file open error. Display the message “File Open Error” and exit if the exception occurs
6. Display all the circles in this vector using the toString method
7. Use an iterator to iterate through the vector to display these circles
8. Display the count of all the circles in the vector using the getCount method
9. Display the count of all the circles in the vector using the vector size method
10. -> Erase all circles which have a radius greater than 8
11. -> Display the number of circles remaining using vector size method
12. -> Display all the circles remaining using toString()
13. -> create Circle object circle1 at (3,4) and radius 7
14. -> create a Circle object circle2 at (-2,-4) and radius 4
15. -> insert these circles into the vector at positions 2 and 3 respectively
16. -> Display the vector of circles
17. -> Write a simple destructor in the Circle.cpp class that simple displays

“In Destructor”

B. Write functions in your main driver cpp file that perform the actions 10-17 Your code should be modular and your main program should consist primarily of function calls

C. Make sure your program has good documentation and correct programming style

D. Your program needs to follow top down design and abide by the software engineering practices that you mastered in

Paper much better compared to the one prior revision request. References need to be no more than the past 5 years.

First of all, the writer made sure that he completely understood my assignment and all the guidelines before he began writing. My paper was finished very fast and well before the specified deadline. I thought it was written excellently. He definitely completely grasped the topic. Overall, he is a great writer and I couldn't have asked for better.

I finished the first deliverable of a project presentation but had no time to finish my second deliverable. The writer revamped my first deliverable and made it much more appealing! Not only was I impressed with the content but I was so grateful for the time they took to redo the background. I have been under a lot of pressure at work and at home so this has been a great service when I have had little time! I appreciate the detail and help! Always on time and always exceeding expectations!
