Question

I am trying to pass a double-dimensional array to a function, but it throws this error all the time. My code is below:

void initialize_centroids(int *,int,int);(Initialization)

initialize_centroids(centroid[0],noofcentroids,newnoofvar);(inside my main)

void initialize_centroids(int *carray,int p,int q)
{
    int i,j;
    for(i=0;i<p;i++)
    {
        for(j=0;j<q;j++)
        {
           carray[i][j]=i;
        }
    }

    return;
}

Answer 1

You’re passing a pointer to an int (int*), but you’re trying to use two subscripts. Is it a 2D array? Then the parameter needs to be a pointer to a pointer to an int: int**

void initialize_centroids(int**, int, int);

int centroid[][] = ....  // wherever this comes from
initialize_centroids(centroid, noofcentroids, newnoofvar);(inside my main)



void initialize_centroids(int** carray, int p, int q)
{
    int i,j;
    for(i=0;i<p;i++)
    {
        for(j=0;j<q;j++)
        {
            carray[i][j]=i;
        }
    }

    return;
}
