Question

I’m new in C++ but I know well C#, java. But no matter. I want to create checkers game emulation. I edded new event for window – load. This is source of what I’ve did:

private: System::Void Form1_Load(System::Object^  sender, System::EventArgs^  e) {
             int matr[7][7];
             int i, j;
             int prevBlack = 1;
             int prevRow = 0;
             int current = 0;

             for (i = 0; i < 8; i++)
             {
                 if ((i + 1) % 2 == 0)
                 {
                     prevBlack = 0;
                 }
                 else
                 {
                     prevBlack = 1;
                 }

                 for (j = 0; j < 8; j++)
                 {
                     if (prevBlack == 1)
                     {
                         current = 0;
                     }
                     else if (i == 0 || i == 1 || i == 2)
                     {
                          current = 2;
                     }
                     else
                     {
                         current = 1;
                     }

                     matr[i][j] = (int)current;

                     if (current == 1 || current == 2)
                     {
                         prevBlack = 1;
                     }
                     else
                     {
                        prevBlack = 0;
                     }
                 }

                 prevRow = i;
             }
         }

The problem is matr[i][j] = (int)current; At the end of this part of code my program exits. When this part of code is commented window will be displayed.

I don’t know why it is so. array is 8 x 8. I need your help 🙂

Answer 1

When you declare your array as matr[7][7], it will have the size 7×7, and valid indices will be 0..6. But you are accessing this array with indices 0..7, which results in an error.

You should declare the array as matr[8][8] since you need a 8×8 array.
