Answer:
To draw a circle, square inscribed in the circle, and square circumscribed by the circle using OpenGL in a window of size 400 by 400, you will need to follow these steps:
Create an OpenGL window using GLFW or a similar library. Set the window size to 400 by 400 pixels.
Initialize OpenGL and set up the projection matrix to use a 2D orthographic projection with the window size as the dimensions.
Define the vertices for the circle, inscribed square, and circumscribed square. For the circle, you can use a number of line segments to approximate the curve. The inscribed square should be centered at the origin and have sides that are tangent to the circle. The circumscribed square should have sides that pass through the four points where the circle intersects the inscribed square.
Set up the vertex buffer and vertex array objects (VAOs) for each shape and specify the vertex attributes.
In the render loop, clear the window, bind the VAO for each shape, and draw the shapes using the appropriate OpenGL draw function (e.g. glDrawArrays for a circle defined as a set of line segments).
To rotate the elements, you can use glRotatef to apply a rotation transformation to the modelview matrix before drawing the shapes. Use the A and B keys to rotate the elements in opposite directions by 10 degrees.
To create the right-click menu, you can use GLFW's glfwCreateMenu function to create a menu and attach it to the mouse. Add the menu items using glfwAddMenuEntry, and specify a callback function to handle the user's selection. In the callback function, you can use a switch statement or if-else blocks to determine which menu option was selected and perform the appropriate action (e.g. write the exact name of the option to the console).
