4.22 - Two-dimensional array 2: circunference on screen


Create a C# program that declares creates a 70x20 two-dimensional array of characters, "draws" a circumference or radius 8 inside it, and displays it on screen.

Hint: the points in the circumference can be obtained using:
x = xCenter + r * cos angle
y = yCenter + r * sin angle

"sin" and "cos" expect the angle to be measured in radians, instead of degrees. To convert from one unit to the other, you must remember that 360 degrees = 2 PI radians (or 180 degrees = PI radians): float radians = (angle * Math.PI / 180.0);

You might draw 72 points (as there are 360 degrees in a circumference, they would be spaced 5 degreees from each other)

Hint: in C#, cosine is Math.Cos, sine is Math.Sin and PI is Math.PI


using System;

public class Circumference
    public static void Main ()
        int xCenter=35; 
        int yCenter=10; 
        int r = 8;
