returning a double array [][]

Is there a way to return a double array in c++
the array is int theBord[8][8]. :confused:

There is no way to return even a simple array in C++.

Use std::vector< std::vector<int> > or create a struct that contains an array.

You can pass single dimensional arrays around with pointers like:

Code:

---

#include <iostream>

void passing_single_array(int* array_you_passed);

int main(void)
{
        int tmp_array[3];

        passing_single_array(tmp_array);


        std::cout << tmp_array[0] << " " << tmp_array[1] << " " << tmp_array[2] << std::endl;

        return EXIT_SUCCESS;
}

void passing_single_array(int* array_you_passed)
{       
        array_you_passed[0] = 0;
        array_you_passed[1] = 1;
        array_you_passed[2] = 2;
}

Unsure about two dimensional arrays, although char **argv works like this, doesn't it?? *Anyone*

But like Sang-drax said - a struct containing an array is good

You could be setting yourself up for a lot of hidden copying of large amounts of data if you do this.

Why are you doing this?
Arrays are passed as pointers, so there is no real need to also return that as a pointer.

Code:

---

void foo ( int array[8][8] ) {
  // do stuff
  // this will change the array in the caller
}

int main ( ) {
  int board[8][8];
  foo( board );
}

Wow,

Thanks alot Salem, that'll save alot of time and effort in the future!!
