8. Use the following code to describe a rectangle. Assume the rectangle sides are parallel to the x and y axes (no rotation), and that the corners of the rectangle are located properly according to their compass designations in the structure. struct point { int x,y; }; struct rect { struct point ne, se, sw,nw; }; Write a function called RectArea() that returns an integer value equal to the area of the given rectangle. The rectangle should be passed in as an argument. 9. Use the same code to describe a rectangle as given in the previous problem. Write a function called RotateRect() that takes in a rectangle and rotates it 90 degrees clockwise. The function should have one parameter that passes the rectangle in and out. The function should have no return value
