How do I pass an array to a constructor?

[svadhisthana7]

I want to pass an array to a constructor, but only the first value is passed--the rest looks like garbage.

Here's a simplified version of what I'm working on:

#include <iostream>
 
class board
{
    public:
        int state[64];
        board(int arr[])
        {
            *state = *arr;
        }
        void print();
};
 
void board::print()
{
    for (int y=0; y<8; y++)
    {
        for (int x=0; x<8; x++)
            std::cout << state[x + y*8] << " ";
        std::cout << "\n";
    }
}
 
int main()
{
    int test[64] = {
        0, 1, 2, 3, 4, 5, 6, 7,
        1, 2, 3, 4, 5, 6, 7, 8,
        2, 3, 4, 5, 6, 7, 8, 9,
        3, 4, 5, 6, 7, 8, 9,10,
        4, 5, 6, 7, 8, 9,10,11,
        5, 6, 7, 8, 9,10,11,12,
        6, 7, 8, 9,10,11,12,13,
        7, 8, 9,10,11,12,13,14 };
 
    board b(test);
    b.print();
 
    std::cin.get();
    return 0;
}
 

Can someone explain why this doesn't work and how to properly pass an array? Notes: I don't want to copy the array. Also, I'm using MSVC++ 2010 Express.

I found the solution after posting to stackoverflow:

"The name of an array is the address of the first element in it.

Hence the line *state = *arr will set state[0] to arr[0].

Since right now you have defined state as int state[64];, state is const pointer of type int whose address cannot be changed.

You can change it to int *state; and then state = arr will work."
