    <p>Here's my program:</p> <pre><code>#include &lt;iostream&gt; #include &lt;string&gt; using namespace std; template &lt;class T&gt; class Example { private: T data; public: Example() { data = 0; } void setData(T elem) { data = elem; } template &lt;class U&gt; friend ostream&amp; operator &lt;&lt; (ostream &amp;, const Example&lt;U&gt;&amp;); friend ostream&amp; operator &lt;&lt; (ostream &amp;, const Example&lt;char&gt;&amp;); friend string operator + (const Example&lt;char&gt; &amp;, const Example&lt;char&gt; &amp;); template &lt;class U&gt; friend U operator + (const Example&lt;U&gt; &amp;, const Example&lt;U&gt; &amp;); }; template &lt;class U&gt; U operator + (const Example&lt;U&gt; &amp;a, const Example&lt;U&gt; &amp;b) { U c; c = a+b; return(c); } string operator + (const Example&lt;char&gt; &amp;a, const Example&lt;char&gt; &amp;b) { string a1(""); a1+=a.data; a1+=b.data; return(a1); } template &lt;class T&gt; ostream&amp; operator &lt;&lt; (ostream &amp;o, const Example&lt;T&gt; &amp;t) { o &lt;&lt; t.data; return o; } ostream&amp; operator &lt;&lt; (ostream &amp;o, const Example&lt;char&gt; &amp;t) { o &lt;&lt; "'" &lt;&lt; t.data &lt;&lt; "'"; return o; } int main() { Example&lt;int&gt; tInt1, tInt2; Example&lt;char&gt; tChar1, tChar2; tInt1.setData(15); tInt2.setData(30); tChar1.setData('A'); tChar2.setData('B'); cout &lt;&lt; tInt1 &lt;&lt; " + " &lt;&lt; tInt2 &lt;&lt; " = " &lt;&lt; (tInt1 + tInt2) &lt;&lt; endl; cout &lt;&lt; tChar1 &lt;&lt; " + " &lt;&lt; tChar2 &lt;&lt; " = " &lt;&lt; (tChar1 + tChar2) &lt;&lt; endl; return 0; } </code></pre> <p>How do I go about making the two characters into a string that I can return? I've tried multiple ways and I can't seem to get any of them to work. I think it may have something to do with the characters being passed by reference. </p> <p>EDIT: Ok so I got that specific function working with no problems. Now I got it compiled but before anything is displayed, there's a segmentation fault. Something is wrong with the addition for the the U data type. It'll add A and B and return AB, but it won't add 15 and 30. Also, I have to say thank you for all your help. I'm still new to programming and I really appreciate it.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
