在C语言中，弧函数是指用来计算给定角度的正弦、余弦或正切值的函数。C语言中的弧函数包括asin()、acos()和atan()函数，它们分别用于计算给定值的反正弦、反余弦和反正切值

在C编程语言中，有一个选项可以使用给定的半径、中心坐标和弧度来创建一个圆弧。

arc()函数在C的graphics.h库中定义 function is used to create an arc. This arc function is included in graphics.h library in C which contains methods that can draw figures on the output screen.

Syntax

void arc(int x, int y, int startangle, int endangle, int radius);

Now, let's get deep into the function and understand each parameter passed and output returned by the function.

Parameters

x − type = int, function: defines the x coordinate of the center of the arc.

y − type = int, function: defines the y coordinate of the center of the arc.

start angle − type = int, function: defines the starting angle of arc.

entangle − type = int, function: defines the ending angle of arc.

Radius − type = int, function: defines the radius of the arc.

Example

#include <graphics.h>
int main(){
   int gd = DETECT, gm;
   int x = 250;
   int y = 250;
   int start_angle = 155;
   int end_angle = 300;
   int radius = 100;
   initgraph(&gd, &gm, "");
   arc(x, y, start_angle, end_angle, radius);
   getch();
   closegraph();
   return 0;
