Question

Help getting started with a C++ program?

Answer 1

If it was visual basic I could have helped you.

Answer 2

if you are using Turing, i could probably help you with some parts

Answer 3

You need to start with a good data structure for your game board. Having 5 separate arrays of int, each hardcoded to a length of 4, is about the worst choice - inflexible and hard to work with. It would be good if you could allow the player to choose the difficulty, then create the game board of size pre-defined for that level, or even just let the player to choose the dimensions. This should give you some ideas:

int adjCount(const vector< deque* >&, int, int);

typedef struct {

    int row, col;

} coord_t;



int main(int argc, char *argv[]) {

    string in;

    stringstream ss;

    int rows, cols, N, x, y;

    char c;

    time_t t;



    srand((unsigned)time(&t));

    do {

        cout << "Enter (rows, cols): ";

        getline(cin, in);

        ss.clear(); ss.str(in);

    } while ((!(ss >> rows >> c >> cols)) || (rows < 1) || (cols < 1));

   

    vector< deque* > board(rows);

    vector< deque* >::iterator i;

    N = random(1, cols * rows / 2);

    }

Sample run:



Enter (rows, cols): 5, 4

0 1 0 0

1 1 0 0

0 1 0 1

0 0 0 1

1 1 0 0

Enter (row, col): 0, 0

3

Enter (row, col): 3, 3

1

Enter (row, col): 3,2

4

Enter (row, col): 0, 3

0
