new delete 实现动态分配和释放二维数组

int main()
{
    int row, column;
    cin >> row >> column;
    int **p = new int*[row];
    for (int i = 0; i < row; ++i)
    {
        p[i] = new int[column];
    }
    p[row-1][column-1] = 3;
    for (int i = 0; i < row; ++i)
    {
        delete [] p[i];
    }
    delete [] p;
}
