C语言课程设计流星雨.doc

C语言课程设计流星雨的设计功能说明：程序模拟一组流星飞向地面的情景。地面用多行#来表示，流星用大写字母不表示。程序产生一组流星（比如10个），从屏幕顶部下降飞向地面。一组流星中，每个流星的字符颜色是随机的，下降的位置是随机的，下降的速度也是随机的。一个流星下落只能去掉一个#号，当最后一行地面有#被去掉时，程序终止。C语言程序源代码：#include#include#include#includeint main() void load(char liuxin2580,char ground580,int heng10,int lie10); void echo(char out2580,int lie10,int color10); void make(char out2580,char liuxin2580,char mark10,int lie10,int heng10,int color10,int speed10,int exist10); void fall(char out2580,char liuxin2580,int speed10,char ground580,int exist10,int heng10,int lie10); void panduan(char ground580); void con(char out2580,char liuxin2580,char ground580); int exist_or(char liuxin2580); char out2580,liuxin2580,ground580,mark10; int exist10,lie10,heng10,color10,speed10; load(liuxin,ground,heng,lie); srand(int)time(0); con(out,liuxin,ground); echo(out,lie,color); while(1) make(out,liuxin,mark,lie,heng,color,speed,exist);/产生一组10个不同颜色不同字母不同下落速度的流星雨 while(1) con(out,liuxin,ground); echo(out,lie,color); panduan(ground); Sleep(1); fall(out,liuxin,speed,ground,exist,heng,lie); if(exist_or(liuxin)=0) break; return 0;void load(char liuxin2580,char ground580,int heng10,int lie10) /初始化流行数组和地面 int i1,i2; for(i1=0;i125;i1+) for(i2=0;i280;i2+) liuxini1i2= ; for(i1=0;i15;i1+) for(i2=0;i280;i2+) groundi1i2=#; for(i1=0;i110;i1+) hengi1=0; liei1=i1; void echo(char out2580,int lie10,int color10) /将out数组输出到屏幕上 int i1,i2,i3=0; COORD coord; coord.X=0; coord.Y=0; SetConsoleCursorPosition( GetStdHandle( STD_OUTPUT_HANDLE ), coord ); for(i1=0;i125;i1+) i3=0; for(i2=0;i280;i2+) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY); if(i2=liei3) if(outi1i2!= & outi1i2!=#) switch(colori3) case 0: SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_RED);break; case 1: SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_GREEN);break; case 2: SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_BLUE);break; i3+=1; printf(%c,outi1i2); void make(char out2580,char liuxin2580,char mark10,int lie10,int heng10,int color10,int speed10,int exist10) int i1,i2,t,change,base=1; for(i1=0;i110;i1+) hengi1=0; marki1=(abs(rand()%26+65); colori1=abs(rand()%3; while(1) base=0; t=(abs(rand()%80); for(i2=0;i210;i2+) if(t=liei2) base=1; if(base=0) break; liei1=t; speedi1=(abs(rand()%4)+1; liuxin0liei1=marki1; existi1=1; for(i1=0;i110;i1+) for(i2=0;i2liei2+1) change=liei2; liei2=liei2+1; liei2+1=change; void fall(char out2580,char liuxin2580,int speed10,char ground580,int exist10,int heng10,int lie10) int i1,i2; for(i1=0;i110;i1+) if(existi1=1) for(i2=1;i2=20) if(groundhengi1-20liei1=#) liuxinhengi1liei1= ; groundhengi1-20liei1= ; existi1=0; break; int exist_or(char liuxin2580) /判断是否还有流星，如果没有就开始新的make函数 int i1,i2,t=0; for(i1=0;i125;i1+) for(i2=0;i280;i2+) if(liuxini1i2!= ) t=1; break; return t; void panduan(char ground580) /判断最后一行是否有空格 int i,a=0; for(i=0;i80;i+) if(ground4i= ) getchar(); void con(char out2580,char liuxin2580,char ground580) /将流行数组与地面数组整合到o
