1] Write a simple C/C++ program that shows that C/C++ does not check the index range for static one-dimensional arrays, and briefly explain how the program is supposed to check it. 2] Write a simple program in Python to detect whether the scoping of variables is static or dynamic, and briefly explain how the program is supposed to check it.
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()
