array [x] [y] = z //??

i'm reading from deitel & deitel 3rd ed, pg 337

in the above array, is z copied into both subscripts?

here's more of the code

Code:

---


void shuffle (int wDeck [] [13])
{
        int row, column;
        for (int card=1; card<=52; card++)
        {
                do
                {        row=rand() %4;
                        column=rand() %13;
                }
                while (wDeck [row] [column] != 0 );
                wDeck [row][column] =card;//?
        }}

No. The array is two dimesional. The x and y each contain the index number for its dimension, the two combined point to one cell. The assignment: array[x] [y]=z; puts z into that cell.

think of the 2 d array as a checker board. Each squareof the checker board is refered to be a row and a column, but each square may hold any of a variety of things, in checkers it may hold nothing, a red or black checker or a red or black king. The same with the array. Each [x][y] combination represents a different "cell" or space or whatever you want to call it. Each "cell" or space can hold a variety of things, called z in the code you posted, depending on what the type of the array is.
