Create Source file for Header file
<p>I have a file GetL.hxx</p>

<pre><code>#ifndef GetL_included
#define GetL_included
#include &lt;iostream&gt;
using namespace std;
class GetL
{
 public:
    virtual int getWidth();
};
#endif //GetL_include
</code></pre>

<p>Here the class GetL contains only one virtual function. what should i put in source file i.e. in GetL.cxx</p>
