Thread: Passing a 2d array to a function, using the pointer to a 2D array

Hi,

I am trying to make a program, a read from the keyboard a 2d array and print his elements.
It works, but i am not so sure is very good, because when i compile, take a while and it finish with a delay.
When I make debug I obtain a segmentation fault. So, I need some help.
Thank you in advance.

Code:

#include <stdio.h>​
#define ARRAY_ROW 3
#define ARRAY_COL 3​

void WriteArray3(int(*piData)[ARRAY_ROW][ARRAY_COL])
{
    int iRow = 0;
    int iCol = 0;​

    for(iRow = 0; iRow<ARRAY_ROW; iRow++)
    {
        for(iCol = 0; iCol<ARRAY_COL; iCol++)
        {
            printf("\n Element[%d][%d] = ", iRow, iCol);
            scanf("%d", &piData[iRow][iCol]);
        }
        printf("\n");
    }​
}​

void ReadArray3(int(*piData)[ARRAY_ROW][ARRAY_COL])
{
    int iRow = 0;
    int iCol = 0;​

    printf("\n");
    for(iRow = 0; iRow<ARRAY_ROW; iRow++)
    {
        for(iCol = 0; iCol<ARRAY_COL; iCol++)
        {
            printf(" %d ", (*piData[iRow][iCol]));
        }
        printf("\n\n");
    }​
}​

int main()
{
    int aiData[ARRAY_ROW][ARRAY_COL];​

    WriteArray3(&aiData);
    ReadArray3(&aiData);​

    return 0;​
}
