Code outside functions
<p>I have written this code outside all functions:</p>

<pre><code>int l, k;
for (l = 1; l &lt;= node; l++)
{
    for (k = 1; k &lt;= node; k++)
    {
        flow[i][j] = capacity[i][j];
        flow[j][i] = 0;
     }
}
</code></pre>

<p>It is giving me the following error on compilation:</p>

<pre><code>shalini@shalini-desktop:~$ g++ -o output fords.cpp
fords.cpp:63: error: expected unqualified-id before ‘for’
fords.cpp:63: error: expected constructor, destructor, or type conversion before ‘&lt;=’ token
fords.cpp:63: error: expected constructor, destructor, or type conversion before ‘++’ tok
</code></pre>
