2 dimensional arrays passed to a function in c++

I'm working on doing calculations in a two dimensional array

but keep getting a nasty error.

i call the function by :

if(checkArray(array))

and try to pass it in like this:

bool checkArray(double array[][10])  //or double *array[][10] to no avail  

the error is

error: cannot convert ‘double ()[(((unsigned int)(((int)n) + -0x00000000000000001)) + 1)]’ to ‘double’ for argument ‘1’ to ‘bool checkArray(double*)’

code snippet

//array declaration

in开发者_开发百科t n = 10;
double array[n][n];

//function call to pass in array


   while(f != 25)
   {

        cout<<endl;
    cout<<endl;

        if(checkArray(array)) //this is the line of the error
         {
      cout<<"EXIT EXIT EXIT"<<endl;
        }

        f++;

    }

    //function declaration

       bool checkArray(double *array)//, double newArray[][10])
       {
            double length = sizeof(array);
            for(int i = 0; i < length; i++)
            for(int j = 0; j < length;j++)
            {
                double temp = array[i][j];
                    }
         }

When I look at the error you are getting, I have an impression that your function has got invalid declaration. It looks like as if it would expect only one-dimensional array: double*.

However, your question seems a little unclear for me... Could you paste the function code?

Is this really a direct (if edited) copy of your code?

This line:

int n = 10; double array[n][n];

is not valid C++. You can't declare an array with variable dimensions. This would work:

const int n = 10; double array[n][n];

You want to declare checkArray as:

 bool checkArray(double array[][10])

and you absolutely do not want to do this:

double length = sizeof(array);

because that will assign to length the size of a pointer, in bytes (4 or 8.) You need to pass in the number of rows explicitly. Also, you're much better off declaring length as an int, or better yet a size_t.

This seems like a decent resource: http://www.fredosaurus.com/notes-cpp/arrayptr/22twodim.html
