Need Help With a Brute Search

[Mark657]

I need help with just getting something to display but I keep getting an error for comparison between pointer and integer. I'll post code below.

void findPeaks(int board[][COLS], int rows)
{
    bool found;

    while(found = false){
        for(int j = 0; j < rows; j++)
        { for(int k = 0; k < COLS; k++){
            if(board[j][k] > board[j+1][k+1] && board[j] > board[j-1][k-1])
                found = true;
                cout << board[j][k] << "is a relative peak." << endl;
        }
        }
    }
}

It's in the if statement. I just need help getting it to display. I think I've got the searching correct.

Any help would be appreciated. Thanks.

bool findRelativePeak( const int board[][NUM_COLS], int num_rows )
{
    for( int row = 1 ; row < (num_rows-1); ++row ) // only inner rows (skip first and last row)
        for( int col = 1 ; col < (NUM_COLS-1); ++col ) // only inner cols
            if( board[row][col] > board[row+1][col+1] && board[row][col] > board[row-1][col-1] )
            {
                std::cout << board[row][col] << "is a relative peak.\n" ;
                return true;
            }

     return false ; // did not find a relative peak
}

&& board[j] > board[j-1][k-1]
Do you notice any differences between the first board and the second?

Also note that that second is accessing your arrays out of bounds the first time through the loop.
