    <blockquote> <p>Okay, I'm stymied on how to pull a value out of a void type to bring it back to main using a reference variable. I've read the section in my textbook several times but the code snips it gives don't make sense to me and there aren't very many of them. Could someone possibly explain, or give a simple code example?</p> <p>Thanks</p> </blockquote> <p>Here is the code I have, what is supposed to happen is I'm supposed to pull 5 test scores from the user using the first function called by my main. The next function called by main is supposed to call a third function which determines the lowest of the test scores and removes it from the middle function's calculations.</p> <p>I tried running the code (using just text stubs and the variables without calculations) but my variables all show up as that huge number that is the maximum they can be, not the user input they're SUPPOSED to show up as.</p> <pre><code>#include &lt;iostream&gt; #include &lt;cmath&gt; #include &lt;string&gt; using namespace std; int main() { double score1, score2, score3, score4, score5, average; void getScore(double &amp;); void calcAverage(double &amp;); int findLowest(); getScore(score1); getScore(score2); getScore(score3); getScore(score4); getScore(score5); calcAverage(average); cout&lt;&lt;"Let's see what we have here.\n" &lt;&lt;score1&lt;&lt;endl&lt;&lt;score2&lt;&lt;endl&lt;&lt;score3&lt;&lt;endl&lt;&lt;score4&lt;&lt;endl&lt;&lt;score5&lt;&lt;endl&lt;&lt;average; system("pause"); return 0; } void getScore(double &amp;) { double score; cout&lt;&lt;"Please enter a test score."; cin&gt;&gt;score; while(score&lt;0 || score&gt;100) { cout&lt;&lt;"Please enter a valid score."; cin&gt;&gt;score; } } void calcAverage(double &amp;) { int findLowest(); double lowest; cout&lt;&lt;"Yes, I'm a stub."; lowest = findLowest(); } int findLowest() { cout&lt;&lt;"I'm a stub too!"; return 5; } </code></pre>

    1. COYou should explain what exactly it is you don't understand. Otherwise, we're just guessing at what you mean.

    2. CONot sure what you mean by "pull a value out of a void type to bring it back to main using a reference". Can you elaborate more on what it is you're trying to *do*? (don't use the book's terms; just say it).

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.
