错误：从类型struct card *'分配类型'struct card'时出现不兼容的类型

Question

继续在我的某个功能中出现此错误。不确定为什么。

  

错误：从类型struct card

分配到类型struct card *时出现不兼容的类型

Struct card** shuffleDeck(Struct card deck[], int size)
{
 int i, j;
 struct card temp;
 struct card** dealerDeck;
 dealerDeck = malloc(size*sizeof(struct card*)*4);
 for(i=0; i<size; i++)
 {
     dealerDeck[i] = (struct card**)malloc(size*sizeof(struct card));
     j = rand()%size;
     temp = dealerDeck[i]; //ERROR ON THIS LINE
     dealerDeck[i] = dealerDeck[j];
     dealerDeck[j] = temp; //ERROR ON THIS LINE
 }
};

任何帮助表示赞赏！

Answer 1

首先，要使temp = dealerDeck[i];发生temp struct card *temp，请输入struct card *temp = NULL; /* memory allocation */ temp = dealerDeck[i]; /* now its possible */

malloc

同时避免施放var s = "shuan3jia4"; var arr = s.split(/([0-9])/); console.log(arr);。
