Exercise 10. C programming

pcscIs a darRer version of the color d. The Structure is identica to an integer). I to c, except that each member has been multiplied by 0.7 (with the result truncated 10. Th e following structures are designed to store information about objects on a graphics screen: struct point f int x, yi struct rectangle ( struct point upper_left, lower_rigt; ) A point structure stores the x and y coordinates of a point on the screen. A rectangle structure stores the coordinates of the upper left and lower right corners of a rectangle. Write functions that perform the following operations on a rectangle structure r passed as an argument: (a) Compute the area of r. (b) Compute the center of r, returning it as a point value. If either the x or y coordinate of the center isn't an integer, store its truncated value in the point structure. fied version of r. (x and y are additional arguments to the function.) tional argument of type struct point.) (c) Move r by x units in the x direction and y units in the y direction, returning the modi- 2 rue or false.
