Square using Midpoint Circle Algorithm

Drawing a Square using Midpoint Circle Algorithm

In computer graphics, the midpoint circle algorithm is an algorithm used to determine the points needed for rasterizing a circle. Bresenham's circle algorithm is derived from the midpoint circle algorithm. This algorithm is used to draw square. But we can draw many shapes from it with little modifications in the formula.

Below is the code written in C to draw a square using midpoint algorithm.

Note: Just copy the files "CGA.bgi" &" EGAVGA.bgi" from bgi folder to bin. So, if you have copied these 2 files then you can skip writing "C:\\tc\\bgi" in initgraph with just ""(2 double quotes).
