    <p>I have this code, which is basically me trying to learn c++, and I can't figure out why I keep getting the two errors</p> <blockquote> <p>error: request for member 'length' in 'cInputChar', which is of non-class type 'char [0]'</p> </blockquote> <p>and</p> <blockquote> <p>error: invalid conversion from 'char*' to 'char'</p> </blockquote> <p>I think it has something to do with the way I am declaring the char variable <code>cInputChar</code>. The problem is definitely associated with the <code>getChar</code> function.</p> <p><strong>My code is below:</strong></p> <pre><code>int getInteger(int&amp; nSeries); char getChar(char&amp; cSeriesDecision, int nSeries); int main() { int nSeries = 0; char cSeriesDecision = {0}; getInteger(nSeries); getChar(cSeriesDecision, nSeries); return 0; } //The function below attempts to get an integer variable without using the '&gt;&gt;' operator. int getInteger(int&amp; nSeries) { //The code below converts the entry from a string to an integer value. string sEntry; stringstream ssEntryStream; while (true) { cout &lt;&lt; "Please enter a valid series number: "; getline(cin, sEntry); stringstream ssEntryStream(sEntry); //This ensures that the input string can be converted to a number, and that the series number is between 1 and 3. if(ssEntryStream &gt;&gt; nSeries &amp;&amp; nSeries &lt; 4 &amp;&amp; nSeries &gt; 0) { break; } cout &lt;&lt; "Invalid series number, please try again." &lt;&lt; endl; } return nSeries; } //This function tries to get a char from the user without using the '&gt;&gt;' operator. char getChar(char&amp; cSeriesDecision, int nSeries) { char cInputChar[0]; while (true) { cout &lt;&lt; "You entered series number " &lt;&lt; nSeries &lt;&lt; "/nIs this correct? y/n: "; cin.getline(cInputChar, 1); if (cInputChar.length() == 1) { cSeriesDecision = cInputChar; break; } cout &lt;&lt; "/nPlease enter a valid decision./n"; } return cSeriesDecision; } </code></pre>

    1. COSince you're self learning, try and _know_, not _think_ how something is, even if you don't know how to fix the isolated element you can still isolate it... e.g. minimise your code to the minimal needed to reproduce the error!

    3. COYou made a `char` array of size `0`, and then you tried to `getline` into it, and then you tried to do `.length()` on it. None of these things are possible. Which book are you using? And which standard library reference?

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.
