    <p>I asked a much complicated question before here at <a href="https://stackoverflow.com/questions/19362167/generating-unique-random-numbers-in-an-array-using-loop/19365614#19365614">Generating Unique Random Numbers in an Array using Loop</a></p> <p>But I found out I just can't understand all the concepts yet and that there are too many things unknown, so I decided to learn it step by step.</p> <p>So right now I am trying to create a 5x5 board using arrays with random numbers..here is my code:</p> <pre><code> #include &lt;stdio.h&gt; #include &lt;stdlib.h&gt; #include &lt;time.h&gt; //Declare the board size and other variables// //Create the random number generator seed //Loop to create the wanted board size //Plant the random numbers into the board within the loop int main() { //Initialize Variables int randomNumber; int rows; int columns; //Declare board size. Size of board is 5 x 5 int board[5][5]; //Create the random number generator seed srand(time(NULL)); //Assign the random numbers from 1 - 25 into variable randomNumber randomNumber = rand() %25 + 1; //Create the rows for the board for ( rows = 1; rows &lt;= 5 ; rows++ ) { //Create the columns for the board for ( columns = 1; columns &lt;= 5 ; columns++ ) { //Assign variable randomNumber into variable board board[randomNumber][randomNumber]; } //Newline after the end of 5th column. printf("\n"); } //Print the board printf("%d\t", board[randomNumber][randomNumber]); }//end main </code></pre> <p>The last part <code>board[randomNumber][randomNumber];</code> is where I think I got really confused. I really don't know what to do with it.</p> <p>I'm trying to assign random numbers into the board, which I got it awfully wrong.</p> <p>Any pointers guys?</p>

    1. CORemember that arrays start at position 0. So, something like `int table[5]` contains items from `table[0]` to `table[4]`. Do Not access `table[5]`.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
