是第四个while循环出不来

ID:434807 · 发表于 2018-12-3 08:39

当while（）中的语句为真时，执行一遍{}里的内容，直到（）内不为真，退出该循环，执行下一步指令

ID:396960 · 发表于 2018-12-3 09:45

第3个while里Move++，加到=16跳出来，又被你Move=0了，那就被你摁在第2和第3个while了。。

ID:308437 · 发表于 2018-12-3 09:53

Move++; //移动一步
这里一直加，到最后，肯定就跳出循环了

ID:94031 · 发表于 2018-12-3 09:59

这是循环成立的条件：while(Move<16)
每循环一次 Move++;
循环16次，就不满足循环条件，跳出循环。

ID:358930 · 发表于 2018-12-3 10:34

while(tome_count<9) //怎么样跳出这个循环？？？？？？？？
{
}

zimuo=0;
}
}这个不是定义吗，while(tome_count<9),就是计数大于9后为假，跳出。

ID:438194 · 发表于 2018-12-3 12:20

这是循环成立的条件：while(Move<16) 每循环一次 Move++; 循环16次，就不满足循环条件，就是让循环的条件不满足循环
