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*PIrad += 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=1i<ti++)

{

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d *****/

Jet[i].x = -240// 烟花d左上角坐标

Jet[i].y = -240

Jet[i].hx = -240// 烟花d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d闪烁图片下标

Jet[i].shoot = false// 是否发射

}

常用的编程语言。

编程语言一：C语言

C语言是世界上最流行、使用最广泛的高级程序设计语言之一。在 *** 作系统和系统使用程序以及需要对硬件进行 *** 作的场合，用C语言明显优于其它高级语言，许多大型应用软件都是用C语言编写的。

编程语言二:java

Java是一种可以撰写跨平台应用软件的面向对象的程序设计语言，是由Sun Microsystems公司于1995年5月推出的Java程序设计语言和Java平台（即JavaSE, JavaEE, JavaME）的总称。

编程语言三:c++

C++这个词在中国大陆的程序员圈子中通常被读做“C加加”，而西方的程序员通常读做“C plus plus" , "CPP”。 它是一种使用非常广泛的计算机编程语言。C++是一种静态数据类型检查的、支持多重编程范式的通用程序设计语言。
