There are five valid input commands: • add x₁ 3₁ 22 Y2 ... In yn: adds an n-gon with vertices located at coordinates (2₁, 31), (x2, y2),... (En. Yn) to the list of all polygons. The newly added polygon must have its shift Direction set to NONE. • summary: prints the program's list of polygons. For each polygon, you need to print the number of vertices and the x-y coordinates of the polygon's centroid. To avoid the complications of calculating the centroid, you can assume that the x-coordinate (y-coordinate) of a polygon's centroid is equal to the average of x-coordinates (y- coordinates) of the polgyon's vertices. • (15 % bonus) turn k x: updates the shift Direction of polygon stored at index k of the program's list of polygons. The shift Direction has to be updated based on the value of that can be equal to one of the following strings: - left - right . - up - down -right-up or up-right -left-up or up-left - right-down or down-right - left-down or down-left 1 . (15% bonus) shift k s: updates the x-y coordinates of vertices of polygon stored at index k of the program's list of polygons. To update the vertices' coordinates of a polygon, you need to check its shift Direction. If the direction is NONE, then the shift command has no side effect. If the direction is RIGHT(LEFT), then s has to be added to(subtracted from) the x-coordinate of every vertex of the polygon. If the direction is UP(DOWN), then s has to be added to(subtracted from) the y-coordinate of every vertex of the polygon. If the direction is RIGHT and UP, then s has to be added to both the x- coordinate and y-coordinate of every vertex of the polygon, etc. quit: ends the program
In this assignment, you are asked to write a program that stores and manipulates a list of at-most n polygons where n is given as a command-line argument when running the program. Each polygon must be stored in a structure like this: typedef struct { int numberOfVertices; Direction shift Direction; Vertex* vertexList; }Polygon; where Direction and Vertex are defined like this: typedef enum { NONE = 0, UP = 1, DOWN = 2, LEFT = 4, RIGHT = 8 }Direction; typedef struct { int x, y; }Vertex; 1 Program Input Commands There are five valid input commands: add ₁ ₁ 2 2 In Yn: adds an n-gon with vertices located at coordinates (1, Y₁), (2, 2),..., (n. Yn) to the list of all polygons. The newly added polygon must have its shift Direction set to NONE. summary: prints the program's list of polygons. For each polygon, you need to print the number of vertices and the x-y coordinates of the polygon's centroid. To avoid the complications of calculating the centroid, you can assume that the x-coordinate (y-coordinate) of a polygon's centroid is equal to the average of x-coordinates (y- coordinates) of the polgyon's vertices.
