Question

我正在编写一个二维数组程序，我遇到问题要打印出来，我不确定我现在正在做我的二维数组正确传递，因为它崩溃而不是运行。任何建议都会有所帮助

void initialize(int* one, int** two);
void replace(int* arr,int rows, int cols,int value);
void fill(int* arr, int rows, int cols);
void print(int** arr, int rows, int cols);

ofstream outfile;
ifstream infile;
int arrayOne[100][100];
int arrayTwo[100][100];

int main(){

    int rows,cols=0;

    cout << "Please input how many rows you would like in the array:  ";
    cin >> rows;
    cout << "Please input how many columns you would like in the array:  ";
    cin >> cols;

    fill(arrayOne[100][100],rows,cols);
    //print(arrayOne[100][100],rows,cols);

    system("pause");
    return 0;
}

void initialize(int* one, int* two){
    for(int i=0;i<100;i++){
        for(int j=0;j<100;j++){
            arrayOne[i][j]=0;
            arrayTwo[i][j]=0;
        }
    }
}

void replace(int* arr,int rows,int cols,int value){
    arr[rows][cols]=value;
}

void fill(int* arr, int rows, int cols){
    int i=0;
    for(int r=0; r < rows; r++){
        for(int c=0; c < cols; c++){
            replace(arr,r,c,i++);
        }
    }
}

void print(int** arr, int r, int c){
    for(int i=0;i<r;i++){
        for(int j=0;j<c;j++){
            cout << arr[i][j] << " ";
        }
        cout << endl;
    }
}

如果您阅读了错误消息，则会明确指出您的问题。话虽如此，它并没有明确说明如何解决它。你将使用固定阵列走上一条艰难的道路......

/* arrayOne[100][100] This is an 'int' at the 101st row and 101st column.
 * It isn't an address to anywhere in the array, in fact it is just beyond
 * the end of your array.
 *
 * Regardless, even if it were a pointer, it would point to a location in memory
 * that is not yours. We count starting with 0 in C/C++. So if you'd like to
 * reference the 'whole' array  just pass it bare:
 */
fill (arrayOne, rows, cols);

/* Of course this means that you need to fix the definition of 'fill'
 * and 'replace'.
 */
void replace(int arr[100][100],int rows,int cols,int value){
    arr[rows][cols]=value;
}

/* As you can see this isn't going to be friendly */
void fill(int arr[100][100], int rows, int cols){
    int i=0;
    for(int r=0; r < rows; r++){
        for(int c=0; c < cols; c++){
            replace(arr,r,c,i++);
        }
    }
}

您还有其他问题，但在遇到问题时可以在其他问题中提出这些问题。

Answer 2

将所有int * arr和int ** arr更改为int arr [100] []或更改为arr [] [100]。我不记得是哪一个。但是，这肯定是其中之一。

“int”类型的参数与参数类型“int **”不兼容
