请大家帮我看看怎么改

#include
#include//图形库

#include
struct Balloon
{
double x;
double y;
COLORREF color;
double vx = 0.0;
double vy = -((rand() % 10) / 10.0 + 0.1);//上升速度
};

void balloon_init(Balloon* ball, double x, double y)
{
ball->x = x;

ball->y = y;

ball->color = RGB(rand()%256,rand()%256,rand() % 256）;//随机颜色

}
void balloon_(Balloon* ball)
{
ball->x = x;

ball->y = y;

ball->color;
{

    setfillcolor(balls->color);//填充颜色
    solidellipse(ball->x, ball->y, ball->x + 30, ball->y + 60); //实心椭圆

    arc(ball->x + 5, ball->y + 5, ball->x + 30 - 5, ball->y + 60 - 5, 0, 1.2);//绘制圆弧高光
    arc(ball->x, ball->y + 60, ball->x + 30 - 10, ball->y + 60 + 20, 0, 1.2);//绘制圆弧尾巴

}
void balloon_moveby(balloon * ball, double dx, double dy)
{
ball->x += dx;
ball->x += dy;

    if (ball->y + 60 < 0)//气球循环
    {
        ball->y = getheight();
        ball->x = rand() % getwidth();
    }


}
int main()
{
    initgraph(480, 480);//绘制窗口

    srand(time(NULL));//时间随机
    IMAGE bking;//插入图片
    setbkmode(TRANSPARENT)
        loadimage(&bking, "./program/OIP-C.jpg,480,480");

    Balloon balls[15] = { 0 };
    for (int i = 0; i < 15; i++)
    {
        balloon_init(balls + i, rand() % getwidth(), rand() % getheight());
        balloon_draw(balls + i);

    }
    while (true)
    {
        beginbatchDraw();
        cleardevice();//清屏
        putimage(0, 0, &bking);//打印背景
        for (int i = 0; i < 15; i++)
        {
            balloon_moveby(balls + i, 0, -1);//移动
            balloon_draw(balls + i);
        }
        EndbatchDraw（）;
        sleep(100);//延时

    }
    getchar();
    return 0;
} 

easyx用的#include <graphics.h>
错误太多了。
void balloon_(Balloon *ball)中x,y，ball->color;后面的｛，
loadimage(&bking, "./program/OIP-C.jpg,480,480");改为loadimage(&bking, "./program/OIP-C.jpg",480,480);
等等根据提示改吧。
