Basically I’m trying to make a chess engine in c++, and to store the board I use 2d string array define as string board[8][8] = startingBoard (startingBoard is a macro). The initialisation works well and does not produce any errors or warnings.
But, when I tried to make a void function to reset the board :

inline void resetBoard()
{
    board = startingBord;
}

it gives me me two errors at compile time:

• at board: Expression must be a modifiable lvalue
• at startingBoard: too many initializer values

I’ve also tried to set each values individually :

void resetBoard()
{
    string sb[8][8] = startingBord;
    int i = 8;
    int j = 8;
    while (i--) {
        while (j--) {
            board[i][j] = sb[i][j];
        }
    }
}

which did not give me errors at compile time but did crash the programm when the function was called.
