Thread: Print matrix spirally

Print a matrix in spiral order

e.g:
1 2 3
4 5 6
7 8 9

should be printed like
1 2 3 6 9 8 7 4 5

Code:

void PrintSpiralMatrix(int **matrix, int m_size)
{ 
	int j = 0;
	for (int i = m_size - 1; i >= 0; i--, j++)
	{
		for (int k = j; k < i; k++)
			cout<<matrix[j][k];
                for (int k = j; k < i; k++)
                	cout<<matrix[k][i];
                for (int k = i; k > j; k--)
	                cout<<matrix[i][k];
                for (int k = i; k > j; k--)
                	cout<<matrix[k][j];
            }
            //print middle element if N is odd
            if (m_size % 2 == 1)
            {
                cout<<matrix[(m_size - 1) / 2][(m_size - 1) / 2] );
            }
	}
}
