Synopsis:
void arc (int x, int y, int startangle, int endangle, int radius);
(x, y) - Center position of arc
startangle - start angle in degrees
endangle - end angle in degrees
radius - radius of the arc
Description:
arc() draws a circular arc for the given angle centered at (x, y)
arc function in c graphics
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>
#include <dos.h>
int main(void) {
/* request auto detection */
int graphicDriver = DETECT, graphicMode;
int code, i, x, y, radius = 0;
int startAngle = 90, endAngle = 180;
/* initialize graphics and local variables */
initgraph(&graphicDriver, &graphicMode,
"C:/TURBOC3/BGI");
/* read result of initialization */
code = graphresult();
/* an error occurred */
if (code != grOk) {
printf("Graphic Error: %s\n",
grapherrormsg(code));
getch();
return 0;
}
x = getmaxx();
y = getmaxy();
setcolor(getmaxcolor());
for (i = 0; i < 100; i++) {
/* draw arc */
radius = radius + 10;
arc(x, y, startAngle, endAngle, radius);
delay(150);
}
/* clean up */
getch();
/* deallocate memory allocated for graphic screen */
closegraph();
return 0;
}
Output: (arc function in c graphics)
