    <p>I am new to stackoverflow as am new to programming, yet am not really a 'professional and enthusiast programmer'. Enthusiast maybe but not professional... </p> <p>In a part of some beginner code of mine i have a two dimensional array <code>diff[i][j]</code>, where the value is zero wherever <code>i==j</code>. I am trying to get the smallest value in each row but not the zero value...</p> <p>the part of the code (under construction) that searches the smallest of the first row is:</p> <pre><code>i=1; double smallest; for ( j=1 ; j&lt;=n ; j++ ) { smallest = diff[i][j]; if ( j!=i &amp;&amp; diff[i][j] &lt; smallest ) smallest = diff[i][j]; } printf("\n %lf\n", smallest); </code></pre> <p>however, the result is always the biggest number not the smallest. Anyone knows why??</p> <p>P.S. I'd be thankful for any suggestion or comment of dealing with stackoverflow.com and the way i asked my question, since am new here... thank you in advance...</p> <p>EDIT after the answers below, i decided to make the i=1 a special case and make two separate functions for both cases... however, when i try to assign j to other variable i failed... in the previous code:</p> <pre><code>if (j!=i &amp;&amp; diff[i][j]&lt;smallest) {smallest=diff[i][j]; d=j} </code></pre> <p>declared d previously and everything... when i print d it prints a random number >maybe the memory location content... tried for debugging to assign an initial value - with the declaration - and when printing it came out the initial value... the point is i want d to hold the column where the smallest value is... how can i acheive that??</p>

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.
