 4. Execute the program and observe what is displayed in the window `Application Output`. Notice the difference between the content of the variables `argValue` and `argRef` despite the fact that both had the same initial value, and that `paramValue` and `paramRef` were assigned the same value. Explain why the content of `argValor` does not change, while the content of `argRef` changes from 0 to 1.

 2. Now you will create an overloaded function `circle` that receives as arguments the value of the angle $$t$$, the reference to the variables $$x$$ and $$y$$, and the value for the radius of the circle. Call the overloaded function `circle` that you just implemented from `main()` to calculate the values of the coordinates $$x$$ and $$y$$ for the circle with radius 15 and draw its graph. Graph the circle within the `wCircle` object. To do this, you must call the method functions `AddPointToGraph(x,y)`, `Plot` and `show` from `main()`. Remember that these should be preceded by `wCircle`, for example, `wCircle.show()`.
