<h3 class="section">10.6 The break Statement</h3>
<a name="index-break-statement"></a>
<p>The <code>break</code> statement jumps out of the innermost <code>while</code>,
<code>do-until</code>, or <code>for</code> loop that encloses it. The <code>break</code>
statement may only be used within the body of a loop. The following
example finds the smallest divisor of a given integer, and also
identifies prime numbers:
</p>
<div class="example">
<pre class="example">num = 103;
div = 2;
while (div*div <= num)
if (rem (num, div) == 0)
break;
endif
div++;
endwhile
if (rem (num, div) == 0)
printf ("Smallest divisor of %d is %d\n", num, div)
else
printf ("%d is prime\n", num);
endif
</pre></div>
<p>When the remainder is zero in the first <code>while</code> statement, Octave
immediately <em>breaks out</em> of the loop. This means that Octave
proceeds immediately to the statement following the loop and continues
processing. (This is very different from the <code>exit</code> statement
which stops the entire Octave program.)
</p>
<p>Here is another program equivalent to the previous one. It illustrates
how the <var>condition</var> of a <code>while</code> statement could just as well
be replaced with a <code>break</code> inside an <code>if</code>:
</p>
<div class="example">
<pre class="example">num = 103;
div = 2;
while (1)
if (rem (num, div) == 0)
printf ("Smallest divisor of %d is %d\n", num, div);
break;
endif
div++;
if (div*div > num)
printf ("%d is prime\n", num);
break;
endif
endwhile
</pre></div>
