Question

The following structures are designed to store information about objects in a Cartesian coordinate system: struct point {int x, y}: struct rectangle {int upper_left_x, upper_left_y/lower_right_x, lower_right_y;}: A point structure stores the x and y coordinates of a point. A rectangle structure stores the coordinates of the upper left and lower right corners of a rectangle. Which of the following functions will correctly determine whether a point p lies within rectangle r, return l(true) or O(false)? a) int is_inside(struct point p, struct rectangle r){ return p.x > = r.upper_left_x && p.x = r.upper_left_y && p.y = r.lower_right_x && p.x = r.upper_left_y && p.y = r.upper_left_x && p.x r.lower_right_y && p.y = r.lower_right_x && p.x = r.lower_right_y && p.y

Explanation / Answer

9. Answer (a)

int is_inside(struct point p, struct rectangle r)

{

return p.x >= r.upper_left_x && p.x <= r.lower_x && p.y >= r.upper_left_y && p.y <= r.lower_right_y;

}

because, the structure of a rectangle stores the coordinates of upper left and lower right of a rectangle.
