C PROGRAMMING ONLY PLEASE Define the Circle structure that contains: Two double data fields named x and y that specify the center of the circle. A data field radius. Define the following functions A function that creates a circle with the specified x, y, and radius. and returns a pointer to it. A function get_area(Circle * c) that returns the area of a circle. A function get_perimeter(Circle * c) that returns the perimeter of a circle. A function contains(Circle * c, double x, double y) that returns true if the specified point (x, y) is inside the circle c. A function contains(Circle * c1, Circle * c2) that returns true if c1 is inside c2. A function overlaps(Circle * c1, Circle * c2) that returns true if c1 overlaps with c2. Construct examples to test each of your functions. Deliverable:
