N queen problem for c++.

It must include the following functions:

bool** ReadChessboard(char* filepath, int& num_rows, int& num_cols);

void PrintChessboard( bool** board, int num_rows, int num_cols);

int main(int argc, char* argc[]);

Here is some of the code provided. I need the code for where it say "Modify and enter your code here."

#include

#include

using namespace std;

bool** ReadChessboard(char* filepath, int& num_rows, int& num_cols)

{

fstream infile;

infile.open(filepath);

infile >> num_rows;

infile >> num_cols;

/////////////////////////////////////////////////////////////////

// Modify and enter your code here, to create board with adding

// queens into the board.

return NULL;

/////////////////////////////////////////////////////////////////

}

void PrintChessboard(bool** board, int num_rows, int num_cols)

{

cout << "Print chess board:" << endl << endl;

/////////////////////////////////////////////////////////////////

// Enter your code here, to print chess board with queens.

// Print

// * " Q" to print a queen, and

// * " ." to print an empty cell.

}

/////////////////////////////////////////////////////////////////////

// Add your own functions if you need

/////////////////////////////////////////////////////////////////////

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

{

if(argc <= 1)

{

cout << "Need the input file containing chess board size and queen locations." << endl;

return 0;

}

int num_rows;

int num_cols;

bool** board = ReadChessboard(argv[1], num_rows, num_cols);

PrintChessboard(board, num_rows, num_cols);

bool is_nqueens = false;

bool there_are_attacks = false;

/////////////////////////////////////////////////////////////////

// Enter your code here.

// If you want create your own functions

/////////////////////////////////////////////////////////////////

if(is_nqueens)

cout << "Solution to the N Queen Problem? Yes" << endl << endl;

else

cout << "Solution to the N Queen Problem? No" << endl << endl;

if(there_are_attacks)

{

cout << "There is at least one queen attacking other queen(s)." << endl;

/////////////////////////////////////////////////////////////////

else

{
