pieslice() function in C
pieslice() draws and fills a pie slice with center at (x, y) and given radius r. The slice travels from s_angle to e_angle which are starting and ending angles for the pie slice. The angles for pie-slice are given in degrees and are measured counterclockwise.
Syntax :
void pieslice(int x, int y, int s_angle, int e_angle, int r); where, (x, y) is center of the circle. r is the radius of the circle. s_angle and e_angle are the starting and ending angles respectively.
Examples :
Input : x = 300, y = 300, s_angle = 0 , e_angle = 120, r = 150 Output : Input : x = 300, y = 300, s_angle = 30 , e_angle = 100, r = 200 Output :
Below is the implementation for the pieslice() function:
// C Implementation for drawing pieslice #include <graphics.h> // driver code int main() { // gm is Graphics mode which // is a computer display mode // that generates image using pixels. // DETECT is a macro defined in // "graphics.h" header file int gd = DETECT, gm; // initgraph initializes the // graphics system by loading a // graphics driver from disk initgraph(&gd, &gm, "" ); // pieslice function pieslice(300, 300, 0, 120, 150); getch(); // closegraph function closes the // graphics mode and deallocates all // memory allocated by graphics system . closegraph(); return 0; } |
