vs 2022 c++画图

怎么在vs 2022 c++用graphics.h画一个带缺口的圆线
像下面这样的

#include <graphics.h>

int main() {
    int gd = DETECT, gm;
    initgraph(&gd, &gm, "");

    int xc = 300, yc = 200;  
    int radius = 50;  
    int start_angle = 45;  
    int end_angle = 135;  
    
    int x = 0, y = radius;
    int d = 3 - 2 * radius;
    while (x <= y) {
        putpixel(xc + x, yc + y, WHITE);
        putpixel(xc - x, yc + y, WHITE);
        putpixel(xc + x, yc - y, WHITE);
        putpixel(xc - x, yc - y, WHITE);
        putpixel(xc + y, yc + x, WHITE);
        putpixel(xc - y, yc + x, WHITE);
        putpixel(xc + y, yc - x, WHITE);
        putpixel(xc - y, yc - x, WHITE);

        if (d < 0) {
            d += 4 * x + 6;
        } else {
            d += 4 * (x - y) + 10;
            y--;
        }
        x++;
    }

    int start_x = xc + radius * cos(start_angle * 3.14 / 180);
    int start_y = yc - radius * sin(start_angle * 3.14 / 180);
    int end_x = xc + radius * cos(end_angle * 3.14 / 180);
    int end_y = yc - radius * sin(end_angle * 3.14 / 180);
    line(start_x, start_y, end_x, end_y);

    getch();
    closegraph();

    return 0;
}

运行结果：

代码：

#include <graphics.h>
#include <conio.h>

#define PI 3.14159
int main() {
    initgraph(640, 480); // 初始化图形界面
    setbkcolor(WHITE); // 设置背景色为白色
    cleardevice(); // 清空屏幕

    int xcenter = 200;
    int ycenter = 200;  //圆的中心点坐标
    int radius1 = 100,radius2=80; //外圆半径、内圆半径
    //setcolor(RED);         /*设置绘图颜色为红色*/
    setfillcolor(RED);
    solidpie(xcenter - radius1, ycenter - radius1, xcenter + radius1, ycenter + radius1, -PI/3, PI+PI/3);    /*画圆弧*/
    setfillcolor(WHITE);
    solidpie(xcenter - radius2, ycenter - radius2, xcenter + radius2, ycenter + radius2, -PI / 3-0.01, PI + PI / 3+0.01);    /*画圆弧*/ //0.01是消除外圆虚线
    _getch();
    closegraph();         /*退出图形状态*/
    return 0;
}

void arc(int left, int top, int right, int bottom, double stangle, double endangle);    // 画椭圆弧(起始角度和终止角度为弧度制)
