c++ - "error: invalid conversion from ' int' 到 'int (*)[8]' [-fpermissive] 的含义是什么？

Question

#include <iostream>

using namespace std;

enum {ROW = 7, COLUMN = 8};

void show(int matrix[][COLUMN], int, int);

int main (){

    int horizontal = 0;
    int vertical = 5;
    int goldCoin[ROW][COLUMN] = {
                            {5, 1, 0, 4, 1, 1, 2, 0},
                            {0, 3, 2, 1, 0, 3, 0, 1},
                            {4, 3, 0, 6, 5, 0, 1, 0},
                            {3, 1, 0, 3, 4, 0, 1, 3},
                            {0, 5, 2, 0, 1, 1, 5, 1},
                            {2, 1, 6, 1, 6, 0, 2, 1},
                            {0, 0, 4, 3, 2, 3, 0, 2}
                        };

    show(goldCoin[ROW][COLUMN], 1, 1);
    return 0;
}

void show(int matrix[][COLUMN], int x, int y){
    if(y >= COLUMN)
        cout << "[error: column index is beyond array limit]" << endl;
    else
        cout << "[" << matrix[x][y] << "]" << endl;
}

The error is pointing to the function call 'show(goldCoin[ROW][COLUMN], 1, 1);' inside main. As a beginner I don't see any syntactical errors on that statement. Can somebody help?

Answer 1

在调用 show(goldCoin[ROW][COLUMN], 1, 1); 时，您传递的是 int 作为第一个参数，而不是二维数组，因为您可能想要。

我相信您打算改为执行 show(goldCoin, 1, 1);。
