制作一个指定概率(例如10%)的抽奖系统。(用C语言写一个程序)

# include & ltstdio.h & gt

# include & ltstdlib.h & gt

void main()

{

int r,p;

char buf

Printf("请输入概率:(例如:概率10%,输入10)\ n ");

scanf("%d ",& ampp);

scanf("%c ",& ampbuf);

while(1)

{

r = rand()% 10 * 10/p;

如果(r==0)

{

Printf("恭喜你中了彩票!");

}

其他

{

Printf("不要赢!");

}

printf(" \ n ");

Printf("回车继续!\ n ");

scanf("%c ",& ampbuf);

如果(buf!='\n ')

打破;

}

}
