    <p><strong>JUST one line</strong><br> I have thought very carefuly about your question and I have tried to write a highly efficient and performant piece of code To print all divisors of a given number on screen we need just one line of code! (use option -std=c99 while compiling via gcc)</p> <pre><code>for(int i=1,n=9;((!(n%i)) &amp;&amp; printf("%d is a divisor of %d\n",i,n)) || i&lt;=(n/2);i++);//n is your number </code></pre> <p>for finding numbers of divisors you can use the following very very fast function(work correctly for all integer number except 1 and 2)</p> <pre><code>int number_of_divisors(int n) { int counter,i; for(counter=0,i=1;(!(n%i) &amp;&amp; (counter++)) || i&lt;=(n/2);i++); return counter; } </code></pre> <p>or if you treat given number as a divisor(work correctly for all integer number except 1 and 2) </p> <pre><code>int number_of_divisors(int n) { int counter,i; for(counter=0,i=1;(!(n%i) &amp;&amp; (counter++)) || i&lt;=(n/2);i++); return ++counter; } </code></pre> <p>NOTE:two above functions works correctly for all positive integer number except number 1 and 2 so it is functional for all numbers that are greater than 2 but if you Need to cover 1 and 2 , you can use one of the following functions( a little slower)</p> <pre><code>int number_of_divisors(int n) { int counter,i; for(counter=0,i=1;(!(n%i) &amp;&amp; (counter++)) || i&lt;=(n/2);i++); if (n==2 || n==1) { return counter; } return ++counter; } </code></pre> <p>OR</p> <pre><code>int number_of_divisors(int n) { int counter,i; for(counter=0,i=1;(!(i==n) &amp;&amp; !(n%i) &amp;&amp; (counter++)) || i&lt;=(n/2);i++); return ++counter; } </code></pre> <p>small is beautiful :)</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.
