!--第二步:把body改为--

body bgcolor="#fef4d9" OnLoad="initMouseEvents()"

!--第三步:在body区域中加入如下代码--

代码如下：

c语言编程烟花代码简单

c语言编程烟花代码简单如下：

#include "stdlib.h"

#include "graphics.h"

#include "stdio.h"

#include "math.h"

#include "conio.h "

#define PI  3.1425926

main()

{

int gdriver=DETECT,gmode,errorcode;

int a[10],b[10],x,y,c,r,i,j,t;

double rad = 0.0;

/* initialize graphics and local variables */

initgraph(gdriver , gmode ,"");

/* read result of initialization */

errorcode = graphresult();

if (errorcode != grOk)  /* an error occurred */

{

printf("Graphics error : %s/n",grapherrormsg(errorcode));

printf("Please any key to halt:");

getch();

exit(1);  /* terminate with an error code */

}

randomize();

for(;!kbhit();)

{

x=rand()%500+100; /*随机中心坐标*/

y=rand()%300+100;

for(r = 0 ;r = 8 ; r++  )    /*烟花的大小设定*/

{

for(i = 0,rad = 0.0 ; rad 2*PI; rad += 0.78 )  /*设定坐标*/

{

a[i++] = x + (int)r *10* cos(rad);

b[ i ] = y + (int)r *10* sin(rad);

}

t = i;

for(i=1;it;i++)

{

c=rand()%13+1; /*各点的颜色随机*/

setcolor(c);       /*功能:将当前图形屏幕的当前笔画颜色置为color.*/

circle(a[i],b[i],1);/* a[i],b[i] 为圆心 1 为半径 画圆 */

}

delay(10000);

delay(10000);

cleardevice();

函数名: cleardevice         

功  能: 清除图形屏幕 

用  法: void far cleardevice(void);

}

}

getch();

closegraph();

函数名: closegraph

功  能: 关闭图形系统

用  法: void far closegraph(void);

}

初始化烟花参数

void Init( int i )

{

// 分别为：烟花中心到图片边缘的最远距离、烟花中心到图片左上角的距离 (x、y) 两个分量

int r[13] = { 120, 120, 155, 123, 130, 147, 138, 138, 130, 135, 140, 132, 155 };

int x[13] = { 120, 120, 110, 117, 110, 93, 102, 102, 110, 105, 100, 108, 110 };

int y[13] = { 120, 120, 85, 118, 120, 103, 105, 110, 110, 120, 120, 104, 85 };

/**** 初始化烟花 *****/

Fire[i].x = 0; // 烟花中心坐标

Fire[i].y = 0;

Fire[i].width = 240; // 图片宽

Fire[i].height = 240; // 图片高

Fire[i].max_r = r[i]; // 最大半径

Fire[i].cen_x = x[i]; // 中心距左上角距离

Fire[i].cen_y = y[i];

Fire[i].show = false; // 是否绽放

Fire[i].dt = 5; // 绽放时间间隔

Fire[i].t1 = timeGetTime();

Fire[i].r = 0; // 从 0 开始绽放

/**** 初始化烟花弹 *****/

Jet[i].x = -240; // 烟花弹左上角坐标

Jet[i].y = -240;

Jet[i].hx = -240; // 烟花弹发射最高点坐标

Jet[i].hy = -240;

Jet[i].height = 0; // 发射高度

Jet[i].t1 = timeGetTime();

Jet[i].dt = rand() % 10; // 发射速度时间间隔

Jet[i].n = 0; // 烟花弹闪烁图片下标

Jet[i].shoot = false; // 是否发射

}

求大神详解Flash 烟花代码。

var FireTimer:Timer=new Timer(1000);//创建一个定时器，每1000毫秒（即1秒）触发一次

FireTimer.addEventListener(TimerEvent.TIMER,addFire);//给定时器注册侦听，当定时器触发时执行addFire函数

FireTimer.start();//计时器开始运作

var tempRo:Number;//创建一个临时的数字对象，记录烟花的角度

function addFire(e:TimerEvent):void

{

var X:Number=Math.random()*550;//创建一个随机的横坐标值，范围在 0~550间

var Y:Number=Math.random()*400;//创建一个随机的纵坐标值，范围在 0~550间

var color:uint=0xffffff* Math.random();//创建一个随机的颜色值，范围在0x000000~0xffffff之间（这是一个16进制的数值）

trace(color.toString());//在调试面板输出颜色的值，测试用

for(var i:int=0;i100;i++)

{

var mc :MovieClip=new MovieClip();//创建烟花的实体

mc.graphics.beginFill(color);//用刚才的随机颜色填充烟花的内容

mc.graphics.drawCircle(0,0,4+3* Math.random());//绘制烟花的形状（圆形），半径在(4 + 0) ~ (4 + 3)之间，即4~7之间。

mc.graphics.endFill();//终止填充颜色

addChild(mc);//把烟花加载到场景里，使其可见

mc.x=X;//给烟花的横坐标赋值，X就是刚才随机生成的横坐标值

mc.y=Y;//给烟花的纵坐标赋值，Y就是刚才随机生成的纵坐标值

mc.scaleX=mc.scaleY=0.4+Math.random()*0.6;//烟花的长宽在 (0.4 + 0)~(0.4 + 0.6)倍之间随机缩放，即随机缩放为原大小的0.4~1倍

tempRo=Math.random()*360/180;//创建烟花的随机角度

mc.spdX=Math.random()*10*Math.sin(tempRo)*Math.pow(-1,Math.floor(Math.random()*100)%2);//根据随机角度，随机创建烟花沿x轴移动的矢量值，其值为 -10~10之间，记录在mc的动态变量spdX中

mc.spdY=Math.random()*10*Math.cos(tempRo)*Math.pow(-1,Math.floor(Math.random()*100)%2);//根据随机角度，随机创建烟花沿y轴移动的矢量值,其值为 -10~10之间，记录在mc的动态变量spdY中

mc.addEventListener(Event.ENTER_FRAME,FireMove);//给烟花注册帧事件函数，在FireMove函数中同步烟花的效果

}

}

function FireMove(e:Event):void

{

var obj:Object=e.target;//创建一个对象，获得注册事件的对象（烟花）的索引，这个obj就是烟花mc

obj.x+=obj.spdX;//烟花的x坐标每一帧递增spdX个单位，obj.spdX就是刚才的mc.spdX

obj.y+=obj.spdY;//烟花的y坐标每一帧递增spdY个单位，obj.spdY就是刚才的mc.spdY

obj.alpha-=0.05;//烟花每一帧的透明度衰减5%

if(obj.alpha=0)//当烟花的透明度小于或等于0时

{

obj.removeEventListener(Event.ENTER_FRAME,FireMove);//注销烟花的帧事件

//建议这里增加一行代码 removeChild(MovieClip(obj)),从场景里移除已经看不见的烟花，节省资源

}

}

烟花代码的格式是什么

烟花代码的格式是#include "stdlib.h"。

表述不清，没指明是什么的代码。代码就是程序员用开发工具所支持的语言写出来的源文件，是一组由字符、符号或信号码元以离散形式表示信息的明确的规则体系。

代码设计的原则包括惟一确定性、标准化和通用性、可扩充性与稳定性、便于识别与记忆、力求短小与格式统一以及容易修改等。

Linux版本：

当前安装有Linux操作系统，数据中RedHatFedora占据绝对优势——Linux使用者使用该版本占总数的49.49%。Fedora是RedHat推出的重要的一款Linux版本，在每个fedora版本中都是集成最新的Linux软件，特别是服务端软件。

排在第二位的是Ubuntu，受支持数占到总数的23.92%；第三位的是SuSE占9.09%，接下来是Debian，使用率为5.92%。在这里面令人期待的中国本土Linux的让人大失所望。使用率仅占5.16%，几乎只有RedHatFedora的十分之一。
