Write a C Program to Draw Ellipse using graphics. Here’s simple Program to Draw Ellipse using graphics in C Programming Language.
Below is the source code for C Program to Draw Ellipse using graphics which is successfully compiled and run on Windows System to produce desired output as shown below :
SOURCE CODE : :
/* C Program to Draw Ellipse using graphics */ #include<graphics.h> #include<conio.h> #include<stdio.h> void plotpoints(int cx, int cy, int x, int y) { putpixel(cx + x, cy + y, 4); putpixel(cx - x, cy + y, 4); putpixel(cx + x, cy - y, 4); putpixel(cx - x, cy - y, 4); } void main() { int cx, cy, rx, ry; printf("Enter the center "); scanf("%d%d", &cx, &cy); printf("x radius : "); scanf("%d", &rx); printf("y radius : "); scanf("%d", &ry); long rx2 = (long) rx * rx; long ry2 = (long) ry * ry; long trx2 = 2 * rx2; long try2 = 2 * ry2; long p, x = 0, y = ry; long px = 0; long py = trx2 * y; p = (long) ((ry2 - (rx2 * ry) + (0.25 * rx2)) + 0.5); int gd = DETECT, gm = DETECT; initgraph(&gd, &gm, ""); cleardevice(); putpixel(cx, cy, 15); while (px < py) { plotpoints(cx, cy, x, y); x++; px += try2; if (p < 0) p += ry2 + px; else { y--; py -= trx2; p += ry2 + px - py; } } py = trx2 * y; px = try2 * x; p = (long) ((ry2 * (x + 0.5) * (x + 0.5) + rx2 * (y - 1) * (y - 1) - rx2 * ry2) + 0.5); while (y >= 0) { plotpoints(cx, cy, x, y); y--; py -= trx2; if (p > 0) p += rx2 - py; else { x++; px += try2; p += rx2 - py + px; } } getch(); }
Above is the source code for C Program to Draw Ellipse using graphics which is successfully compiled and run on Windows System.The Output of the program is shown above .
