Draw a Circle using Mid-Point Algorithm
Write a C Program to Draw a Circle using Mid-Point Algorithm. Here’s simple Program to Draw a Circle using Mid-Point Algorithm in C Programming Language.
Below is the source code for C Program to Draw a Circle using Mid-Point Algorithm which is successfully compiled and run on Windows System to produce desired output as shown below :
SOURCE CODE : :
/* C Program to Draw a Circle using Mid-Point Algorithm */ #include<graphics.h> #include<conio.h> #include<stdio.h> void plotpoints(int x, int y, int cx, int cy) { putpixel(cx + x, cy + y, 4); putpixel(cx - x, cy + y, 4); putpixel(cx + x, cy - y, 4); putpixel(cx - x, cy - y, 4); putpixel(cx + y, cy + x, 4); putpixel(cx - y, cy + x, 4); putpixel(cx + y, cy - x, 4); putpixel(cx - y, cy - x, 4); } void main() { int cx, cy, x = 0, y, r, p; int gd = DETECT, gm = DETECT; clrscr(); printf("Enter the center \n"); scanf("%d%d", &cx, &cy); printf("Enter the radius : "); scanf("%d", &r); y = r; p = 1 - r; initgraph(&gd, &gm, ""); cleardevice(); while (x < y) { plotpoints(x, y, cx, cy); x++; if (p < 0) p += 2 * x + 1; else { y--; p += 2 * (x - y) + 1; } } getch(); }
Above is the source code for C Program to Draw a Circle using Mid-Point Algorithm which is successfully compiled and run on Windows System.The Output of the program is shown above .
