Question

I want to write a function in C language which returns the 2 dimension array to my main function.

Answer 1

A function that returns a dynamically allocated two dimensional array for the int type.

int ** myfunc(size_t width, size_t height) 
{
    return malloc(width * height * sizeof(int));
}

It has to be deleted with free once it is not used anymore.

EDIT This only allocates the space for the array which could be accessed by pointer arithmetic but unfortunately not by the index operators like array[x][y].

If you want something like this here is a good explanation. It boils down to something like this:

int ** myfunc(size_t ncolumns, size_t nrows)
{
    int **array;
    array = malloc(nrows * sizeof(int *));
    for(i = 0; i < nrows; i++)
    {
        array[i] = malloc(ncolumns * sizeof(int));
    }
}
