"int" declarations are missing for some functions and also for argv parameter to function

            <codeblock outputclass="cpp"> 1        #include &lt;QApplication&gt;
 2        #include &lt;QTextEdit&gt;
 3
 4         main&lt;/@func&gt;( argv, char **args)
 5        {
 6            <xref href="qapplication.xml">QApplication</xref> app(argv, args);
 7
 8            <xref href="qtextedit.xml">QTextEdit</xref> textEdit;
 9            textEdit.show();
10
11            return app.exec();
12        }</codeblock>
