Trouble with exception handling

[theox]

ONCE I WIN OR LOSE THE OUTPUT OF THE BOARD GETS MESSED UP.

#include <iostream>
#include <stdexcept>
#include <string>
using namespace std;

const int NUMROWS = 5;
const int NUMCOLS = 5;

int moveNumber;
void initialize();
void showBoard(int move);
void placePiece(int &r, int &c, char i, int move);
void moveOpponent(Board board[NUMROWS][NUMCOLS], int &row, int &col, int &move);
};


void Board::initialize(){
Board board[NUMROWS][NUMROWS];
for (int row = 0; row< NUMROWS; row++) {
for (int col= 0; col < NUMCOLS; col++) {
board[row][col].marker = '_';

}

}

}

Board board[NUMROWS][NUMROWS];

}

}

}
}

Without digging through your unformatted code, I will say that this is exactly the wrong way to use exceptions.

[Thomas1965]

There are some issues.

The board looks like this at the beginning:

8 D   A
L % ■ ♀ è
  (   ♦ @
° > j W e
  $ ı ■ ]

You create many local variables of type Board that go out of scope like here.

void Board::initialize ()
{
  Board board[NUMROWS][NUMROWS];
  for (int row = 0; row < NUMROWS; row++)
  {
    for (int col = 0; col < NUMCOLS; col++)
    {
      board[row][col].marker = '_';
    }
  }
}

if((board[row][col].marker != '_')){
   throw runtime_error("YOU COLLIDED!");

In this case an exception is not the right way. It's not an error, collisions are part of a game.

Thank You guys for your input I appreciate it, I was able to figure out what the problem.
