Description
Problem/Question:
– Problem:
– Design an abstract class called Shape that you will use with Circle, Rect, and FilledRect class:
– Private variables double x and y
– Constructor shape (x, y)
– function area take no parameters return double const equal zero
– function draw take ostream file return void and equal zero
– make deconstruct ~Shape
– Hint: you need to use virtual
– Design class Circle that inherit class shape functions
– private variable x, y, radius
– Make the following functions:
– Circle constructor that take x, y, radius, Note that x and y are assigned to Shape(x,y)
– for example constructor_name(double x, double y) : Shape(x,y)
– draw that take ostream file to write postscript instruction the function return void
– area take no parameters and return double
– ~Circle deconstruction
– Design class Rect that inherit class shape with same functions as class Circle
– private variables are x, y, weight, height
– Design class FilledRect that inherit class shape with same functions as class Circle
– private variables are x, y, weight, height
– Hint for Circle, Rect, and FilledRect: you will need to use override keyword
– e.g.: data_return_type function_name(inputs) <b>override</b> {}
– Design class Drawing that take all shapes created and save it in vectors. Then use draw function for each Shape to write test.ps file with postscripts instructions
– it has private variables of type: ofstream and vector<Shape> “Polymorphism”
– Drawing constructor that take location to open “test.ps” file.
– void add function that push_back new shapes to vector. It takes “Polymorphism” shape.
– void draw function take no parameter that loop through all shapes and write postscript instruction for each shape.
– void showArea take no parameters and loop inside vector to run area function for each shape class
– void setrgb function take three double for red, green, and blue. It writes postscript to change the color for all shapes.
Postscript language:
– [Check Wiki. for some background about Postscript](https://en.wikipedia.org/wiki/PostScript)
– [You can use online website to view .ps file](https://products.aspose.app/page/viewer/ps)
– Postscript line you need to use to draw shapes are given in the code.
– Your test.ps file should generate the following results

TO-DO:
– clone your repo to your local computer
– ”’ <b>git clone repo_https_url</b> ”’
– repo https url is found under code tab in your github
– Edit your name on top on README.md file.
– Edit the main function (file name: main.cpp):
– Write your classes in main.cpp
– Your code should run fine with main() function and output test.ps file
– Push your answers
– use git in your terminal to add files, and add comments on your commits, and finally submit files
– ”’ <b>git add specific_file1.x specific_file2.x</b> ”’
– ”’ <b>git commit -m “add message here for commits”</b> ”’
– ”’ <b>git push</b> ”’
