WHAT ARE WE GOING TO LEARN?
We will look at mid point circle algorithm
We will look at an example of Mid point circle algorithm.

Algorithm
Step 1: Input radius r and centre (Xc,Yc) and obtain first point on the circumference of the circle centred at the origin(0,0).
Step 2: calculate the initial value of the decision parameter as
P0=5/4-r
Make a table:

4. Determine symmetry points in the other seven octants.
5. Move each calculated pixel position (x, y) onto the circular path centered on (xc, yc) and plot the coordinate values: x=x+xc, y=y+yc
6. Repeat steps 3 through 5 until x is less than or equal to y.
