We looked at the following code to print a chessboard: // Print a chessboard #include #include using namespace std; int main(int argc, char *argv[]) { int i,j,k,l; typedef char box[5][7]; box bb,wb,*board[8][8]; //fill in bb=black box and wb=whitebox for(i=0;i

Thank you!

3. Write a function bool ok(int qlI) which takes an array q and returns true if the array represents a valid configuration of the eight queens and returns false otherwise. 4. Write a function bool ok(int qlI) for the "Eight numbers in a cross" problem. Note that the helper array int al8]15] should be local to the function (and static) since that is the only place that it is used 5. In the "Eight numbers in a cross" problem, if you are given the labeling if the "cross" how do you construct the helper array a. 1
