前幾天因爲測試需要寫了這段自動生成一個鏈表的代碼，貼上來興許以後用得着。
typedef struct card...{
card * previous; char index; card * next;
}CARD;
CARD * cpHead, * pCurrent, * pTmpCard;char i;//生成4個節點的鏈表，表頭用指針cpHead標記for(i = 0; i <= 3; i++)...{ pCurrent = (CARD *)malloc(sizeof(CARD)); pCurrent -> index = i + 65; pCurrent -> next = NULL; 
if(i == 0)...{ pCurrent -> previous = NULL; cpHead = pCurrent; }else...{ pTmpCard -> next = pCurrent; pCurrent -> previous = pTmpCard;
} pTmpCard = pCurrent;}//打印pCurrent = cpHead;while(pCurrent != NULL)...{ printf("%c ", pCurrent -> index); pCurrent = pCurrent -> next;}
