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.

#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;​

}

 

Hallo Dragu!

Here is my suggestion:

Code:

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


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

printf("\nShow Values of array[%d][%d]\n", ARRAY_ROW, ARRAY_COL);

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

printf("-----------------------\n");
}

int main()
{
int aiData[ARRAY_ROW][ARRAY_COL] = {0};
printf("Get values\n");
WriteArray3(&aiData);
ReadArray3(aiData);

return 0;
}
