多维数组 C++ 中数组下标的类型"int[int]"无效

Question

在做我的纸牌游戏课程项目时，我收到此错误
数组下标的无效类型"int[int]"这是代码：

老实说，我仍然是编程新手。所以我不知道我不能从函数返回整个数组。搜索线索后，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，出现了此错误，我不知道我需要修复什么。 当我尝试使用函数参数中的数组时，错误不断出现，例如

if(player1Number[i] == player2Number[j])<br/>

从函数

int** compareCard(int player1Number, int player1Logo, int player2Number, int player2Logo, int cardInfo)

然后继续。

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！(对不起，如果我的英语不好(

Answer 1

你用一堆数组(所以int指针(作为参数来声明compareCard：

int* compareCard(int[5], int[5], int[5], int[5], int[13][4]);

但是，然后，您将使用整数(而不是指针(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，返回类型是错误的。您将其声明为int*，但随后将其实现为int**。您必须确保函数的签名匹配。看起来获取声明的签名并将其应用于定义应该可以修复此编译时错误。

编译器是否为这些函数声明发出任何警告？如果没有，请查看是否可以将其设置为更严格并带有警告。获取潜在错误的正确警告可大大提高调试效率。
