I'm trying to compile the following code that I wrote out:

```
#include <iostream>
#include <cmath>
#include <iomanip>
using namespace std;
void gauss(double, double, double, int);
int main()
{
const int n1 = 4;
double prompt;
double A1[n1][n1] = {{3,0,3,-4},{0,1,1,1},{1,1,1,2},{2,3,1,3}};
double b1[n1] ={7,0,6,6};
double x1[n1];
gauss(A1, x1, b1, n1);
cout << x1;
cout << "\n Enter \'r\' to continue..." << endl;
cin >> prompt;
return 0;
}
void gauss(double A[][4], double x[], double b[], int n)
{
for(int k = 0; k < n; k++)
{
double divisor = A[k][k];
if(divisor == 0)
{
cout << "divisor is zero" << endl;
return;
}
else
for (int i = k + 1; i < n; i++)
{
double multiplier = A[i][k]/divisor;
for(int j = k + 1; j < n; j++)
A[i][j] = A[i][j] - multiplier * b[k];
}
}
if(A[n-1][n-1] == 0)
{
cout << "The last divisor is zero" << endl;
return;
}
for(int i = n - 1; i >= 0; i--)
{
x[i] = b[i];
for(int j = i + 1; j < n; j++)
x[i] = x[i] - A[i][j] * x[j];
x[i] = x[i]/A[i][i];
}
}
return;
}
```

When I do, the following errors come up (Not sure if they're interrelated):** 16 cannot convert `double (*)[4]' to `double' for argument `1' to `void gauss(double, double, double, int)' ****56 expected unqualified-id before "return" ****56 expected `,' or `;' before "return" **

and**57 expected declaration before '}' token **

I'm wondering if perhaps it has something to do with the double data type or if maybe it's actually in the way that I'm passing the variables. I'm using Bloodshed Dev C++ as my compiler, if that helps.
