uj5u.com熱心網友回復：
移動身體部分邏輯有問題，建議嘗試趙老師的單步除錯大法uj5u.com熱心網友回復：
不要依賴除錯器輸出復雜資料結構！而要將復雜資料結構的整個內容在處理它的每一步使用一小段代碼按自己很容易理解的格式輸出，非常有助于除錯！或者可以說是“基礎設施”參考下面：
資料結構對單鏈表進行資料排序 http://bbs.csdn.net/topics/392201633
uj5u.com熱心網友回復：
最明顯的是Judge()if (head->x == 0 || head->x == 50 || head->y == 0 || head->y == 25)
{
freesnake();
return 0;
}
// return 0;
// while (p)
rueturn 0是干嘛的刪了，while (p)不就死回圈了嘛。movebody()
while (p->next)
{
p = p->next;
}
有死回圈幾率，慢慢除錯吧祝你順利
