Read number from text file using C++ stream
<p>I have a text file like below</p>

<pre><code>2 1 2
5 10 13 11 12 14
2 0 1
2 99 2
200 2
1 5
5 1 2 3 4 5
1 0
0 0
</code></pre>

<p>I want to read file line by line, and read the umbers from each line. I know how to use the stream to read a fixed field line, but what about the non-fixed line?</p>

<p>Best Regards,</p>
