Thread: I don't understand pointers & arrays. Keep getting error in compiling

Here is my code:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <math.h>


#define DIMENSION 3
#define SIGN(i, j) pow(-1, i+j)


double det(double entries)
{
  int dim = DIMENSION;
  int k, l, m;
  double submatrix[dim-1][dim-1];
  double det;


  det = 1;
 
  if(dim == 2)
  {
    det = ( (entries[0][0]) * (entries[1][1]) ) - ( (entries[0][1]) * (entries[1][0]) );
    return det;

What I don't understand, is that I keep getting the error message "subscripted value is neither array nor pointer" for the line:

Code:

det = ( (entries[0][0]) * (entries[1][1]) ) - ( (entries[0][1]) * (entries[1][0]) );

Can someone explain what I've done wrong? What is the 'subscripted value'

Ah! thats annoying. So is there no way to pass a multi-dimensional array to a function without saying any of its dimensions?

Thanks, got it sorted now
