Question

1. Use OpenGL + GLUT + C/C++ to write a program to draw a red 2D circle and a rectangle with an output look like the right image. Please use variables to hold the center location (for question 2 below), and use a variable to control the number of line segments you use to approximate circle 2. Add a keyboard-callback function to the above program and make appropriate modification so that you can use key 'x' and 'x' to move the circle and the rectangle left and right, and 'Y' and 'y' to move up and down.
