It is common to all programming languages, that it can be defined as a block reusable code to perform specific tasks. Moreover, in Python, functions are usually a part of Python packages and libraries, whereas the other functions are written by the developers to meet certain requirements. Therefore, what are these function defined by the systems and the developers? Methods/Functions Built-in Function Constructors Class / Object Constructor User-defined Function

Structures The circle has two data members, a Point representing the center of the circle and a float value representing the radius as shown below. typedef struct{ Point center; float radius; }Circle; Make a c project sorting it into main.c circle.h, circle.c and implement the following functions: a. float diameter(Circle circ); //computes the diameter of a circle. b. float area(Circle circ); //computes for area of a circle c. float circumference(Circle circ);//computes for the circumference of a circle. Also add the basic functiona: initCircle(), createCircle() and displayCircle()
