General - Java For ... Loop to C/C++

Hello

Two questions.

The second line m=field.length. What is the actual length?
The line n=field[j].length what is the second value?

I'm trying to convert some java code to c++.

Code:
Code:

           if (field == null) field = new int[cwidth][cheight];
            for (int j = 0, m = field.length; j < m; j++)
            {
                for (int k = 0, n = field[j].length; k < n; k++)
                {
                    field[j][k] += (hashrandom(cx + j, cy + k, iteration) & (1 << (7 - iteration)));
                }
            }

I tried

Code:
Code:
 
        /// Field
        m=cwidth;
        n=cheight;

        if (field == NULL) field = new int[m*(n*m)];

        for (int j = 0; j < m; j++)
        {
            for (int k = 0; k < n; k++)
            {
               field[j+(k*m)] += (hashrandom({cx + j, cy + k, iteration}) & (1 << (7 - iteration)));
            }
        }

but it does not work.

I'm not sure how to convert the for loop properly. As I moved from a two dimensional array to a one dimensional that represents the two dimensions.
