In C++, the pieslice() Function is used to draw and fills a slice of pie starting from a specified angle and up to another specified angle, along the fixed centered point (x, y) with specified radius.
Syntax of pislice() Function
The general syntax of this function looks like this:
Where:
pieslice(x, y, s_angle, e_angle, radius);
| x and y | represent centered point of the pie slice. These are x-coordinate and y-coordinate of the center of pie slice on the screen. |
| s_angle | It represents the starting angle of the arc in degree. |
| e_angle | It represents the ending angle of the arc in degree. |
| radius | It represents radius of the pie. |
Each of the above mentioned parameter can be a constant or variable of "int" data type.
This function can also be used to draw a circle and line. If you want to draw a circle, give the starting angle 0° and ending angle 360°.
In the same way, a line can be draw with this function by giving same values to starting and ending angles.
Example of pieslice() Function
The following C++ program draws a circle using this function.
#include
#include
#include
using namespace std;
main()
{
int d, m, n;
d = DETECT;
initgraph (&d, &m, " ");
cleardevice();
pieslice(300, 200, 0, 360, 90);
getch();
closegraph();
}
