	"""Creates a circle with coordinates as start point."""
	# Pull up the pen first.
	turtle_object.penup()
	# Go to initial coordinates.
	turtle_object.goto(coordinates[0], coordinates[1]);
	# Pendown to start drawing.

Chegg Question

	/**
	* "Sun Apr 09 2017 12:36:54 GMT+0530 (IST)"
	* Design a file filter package.
	*
	* 1) A file filter reads an input file, transforms it in some way, and writes the result to an output file.
	* You are tasked to write an abstract Filter class that defines a pure virtual function char transform
	* (char ch) for transforming a single character .
	*
	* 2) The Filter class should have member variables to hold the input and output streams; it also should
	* have a default constructor that initializes the input/output streams to cin/cout respectively as well

	// You cannot do << to the cin, you can do 'cin >> auto a' though but I
	// think it'd be great to initialize int's first and then getting values.
	cin<< auto a;
	cin<<auto b;

	// This way powerMultiply will already have a power of a.
	int powerMultiply=a;
	// so you need not do it i<b times, you just have to do
	// it i < (b-1) times.
