老实说，我还是编程新手。所以我不知道我不能从函数返回整个数组。在寻找线索之后，我发现我可以使用指针从函数返回数组。当我尝试修复代码时，会出现此错误，并且我不知道需要修复什么。
当我尝试使用函数参数中的数组时，错误会不断出现，例如
if(player1Number[i] == player2Number[j])<br/>
来自功能
int** compareCard(int player1Number, int player1Logo, int player2Number,
int player2Logo, int cardInfo)
及以后。
有人可以帮我解决这个问题吗？对代码的更正将不胜感激。非常感谢你！ （对不起，如果我的英语不好）
答案 0 :(得分：0)
您要声明compareCard，并使用一堆数组（即int指针）作为参数：
int* compareCard(int[5], int[5], int[5], int[5], int[13][4]);
然后，您正在使用整数（不是指针）作为参数来实现它：
int** compareCard(int player1Number, int player1Logo, int player2Number, int player2Logo, int cardInfo)
{
for(int i=0; i<5 ; i++)
您还将它们用作数组：
if(player1Logo[i] < player2Logo[j]) cardInfo[player1Number[i]][player1Logo[i]] = -1;
此外，返回类型错误。您将其声明为int*，然后将其实现为int**。您必须确保函数的签名匹配。看起来，使用声明的签名并将其应用于定义应该可以解决此编译时错误。
您的编译器是否对这些函数声明发出任何警告？如果不是，请查看是否可以设置更严格的警告。正确警告潜在错误，可以大大提高调试效率。
