c语言放烟花代码

#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*/

{

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

}

t = i;

for(i=1;i<t;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);

(1)烟花的代码c语言扩展阅读

C语言:表白显示(多彩小心心)

#include <stdio.h>

#include <math.h>

#include <stdlib.h>

#define I 20

#define R 340

#include <string.h>

int main()

{

char answer[10];

printf("遇到你 我才发现 曾经所有的条件 似乎都成了我等你的借口 ");

printf("我对你的感情已经决堤 所以 请允许我,从今往后映入你 明媚的眼 ");

printf("我 想和你 耳鬓厮磨,相濡以沫!");

printf("答应我吧! 输入yes,你可以看到我的真心 ");

scanf("%s", answer);

float y, x, z, f;

for (y = 1.5f; y > -1.5f; y -= 0.1f)

{

for (x = -1.5f; x < 1.5f; x += 0.05f)

{

z = x * x + y * y - 1;

f = z * z*z - x * x*y*y*y;

putchar(f <= 0.0f ? "*********"[(int)(f*-8.0f)] : ' ');

}

putchar(' ');

}

long time;

for (;;)

{

system("color a");

for (time = 0; time<99999999; time++);

system("color b");

for (time = 0; time<99999999; time++);

system("color c");

for (time = 0; time<99999999; time++);

system("color d");

for (time = 0; time<99999999; time++);

system("color e");

for (time = 0; time<99999999; time++);

system("color f");

for (time = 0; time<99999999; time++);

system("color 0");

for (time = 0; time<99999999; time++);

system("color 1");

for (time = 0; time<99999999; time++);

system("color 2");

for (time = 0; time<99999999; time++);

system("color 3");

for (time = 0; time<99999999; time++);

system("color 4");

for (time = 0; time<99999999; time++);

system("color 5");

for (time = 0; time<99999999; time++);

system("color 6");

for (time = 0; time<99999999; time++);

system("color 7");

for (time = 0; time<99999999; time++);

system("color 8");

for (time = 0; time<99999999; time++);

system("color 9");

}

getchar();

return 0;

}

❷ 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; /*随机中心坐标州纯*/

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;i<t;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:烟花余族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; // 烟花弹竖迹弊发射最高点坐标

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

}
