Passing array of Arrays to a function

I was trying to pass array of arrays to a function, but I am not getting correct results. I looked at [this SO post][1] for this purpose. I am not getting any warnings and I am using TDM GCC 64 compiler. What could be wrong with this code?

#include <stdio.h>
#include<inttypes.h>

void printArrayOfArrays(uint8_t numRows,uint8_t numColumns,int arraOfArray[][numColumns]);


int main(void)
{
    int numRows, numColumns, rowCount, colCount, first[5][5];

    printf("Enter the number of rows and columns of matrix\n");
    scanf("%d%d", &numRows, &numColumns);

    printf("Enter the elements of first matrix\n");

    for (rowCount = 0; rowCount < numRows; rowCount++)
    {
        for (colCount = 0; colCount < numColumns; colCount++)
        {
            scanf("%d", &first[rowCount][colCount]);
        }
    }

    for (rowCount = 0; rowCount < numRows; rowCount++)
    {
        for (colCount = 0 ; colCount < numColumns; colCount++)
        {
            printf("%d\t",first[rowCount][colCount]);
        }
        printf("\n\n");
    }

    printf("\n");

    printArrayOfArrays(numRows,numColumns,first);

    return(0);
}

void printArrayOfArrays(uint8_t numRows,uint8_t numColumns,int arrayOfArray[numRows][numColumns])
{
    for (uint8_t rowCount = 0; rowCount < numRows; rowCount++)
    {
        for (uint8_t colCount = 0 ; colCount < numColumns; colCount++)
        {
            printf("%d\t", *(*(arrayOfArray+rowCount)+colCount));
        }
        printf("\n");
    }
}

The result I am getting for this is

Enter the number of rows and columns of matrix
2
2
Enter the elements of first matrix
4
3
1
6
4       3

1       6

4       3
0       0

Solution

Your array definitions of first in main and of arrayOfArrays in printArrayOfArrays are not consistent: first is a 5×5 array, even if you don't use or initialise all elements; arrayOfArrays is a variable length array, in your example 2×2.

So you should either make first a variable length array, too:

printf("Enter the number of rows and columns of matrix\n");
scanf("%d%d", &numRows, &numColumns);

int first[numRows][numColumns];

(Make sure that you define it only after numRows and numColumns have meaningful values.)

Or you could make the parameter to the function a fixed size array of 5×5:

void printArrayOfArrays(uint8_t numRows, uint8_t numColumns,
    int arrayOfArray[5][5]);

(In this case, you must ensure that numRows and numColumns don't exceed 5.)
