<a name="index-continue-statement"></a>

<p>The <code>continue</code> statement, like <code>break</code>, is used only inside
<code>while</code>, <code>do-until</code>, or <code>for</code> loops.  It skips over the
rest of the loop body, causing the next cycle around the loop to begin
immediately.  Contrast this with <code>break</code>, which jumps out of the
loop altogether.
Here is an example:
</p>
<div class="example">
<pre class="example"># print elements of a vector of random
# integers that are even.

# first, create a row vector of 10 random
# integers with values between 0 and 100:

vec = round (rand (1, 10) * 100);

# print what we're interested in:

for x = vec
  if (rem (x, 2) != 0)
    continue;
  endif
  printf (&quot;%d\n&quot;, x);
endfor
</pre></div>

<p>If one of the elements of <var>vec</var> is an odd number, this example skips
the print statement for that element, and continues back to the first
statement in the loop.
</p>
<p>This is not a practical example of the <code>continue</code> statement, but it
should give you a clear understanding of how it works.  Normally, one
would probably write the loop like this:
</p>
<div class="example">
<pre class="example">for x = vec
  if (rem (x, 2) == 0)
    printf (&quot;%d\n&quot;, x);
  endif
endfor
</pre></div>
