第3個(gè)while里Move++，加到=16跳出來，又被你Move=0了，那就被你摁在第2和第3個(gè)while了。。

這是循環(huán)成立的條件：while(Move<16)
每循環(huán)一次 Move++;
循環(huán)16次，就不滿足循環(huán)條件，跳出循環(huán)。

}這個(gè)不是定義嗎，while(tome_count<9),就是計(jì)數(shù)大于9后為假，跳出。

這是循環(huán)成立的條件：while(Move<16) 每循環(huán)一次 Move++; 循環(huán)16次，就不滿足循環(huán)條件，就是讓循環(huán)的條件不滿足循環(huán)
