    <p>I'm just learning C++ and I need this program to work for class. Logically it works. I'm using bloodshed.net's IDE... and it seems to just ignore the <code>cin &gt;&gt; kwh;</code>. I think its bloodsheds fault, not mine, but I could be mistake.</p> <p>Here the code:</p> <pre><code>#include &lt;iostream&gt; #include &lt;iomanip&gt; using namespace std; int main() { double kwh = -1, monthCost = 0, totalCost = 0; int monthCount = 0; bool nextMonth = 0; do { kwh = -1; cout &lt;&lt; "How many KWH did you use month " &lt;&lt; ++monthCount &lt;&lt; "?\n"; cin &gt;&gt; kwh; if (kwh &lt;= 1000 &amp;&amp; kwh &gt;= 0) { monthCost = kwh * 0.6; } else if (kwh &lt; 0) { cout &lt;&lt; "\nInvalid number of KWH."; while (kwh &lt; 0) { cout &lt;&lt; "How many KWH did you use month " &lt;&lt; monthCount &lt;&lt; "?\n"; // Could you tell me what I'm doing wrong? I honestly think its // the programs fault, not mine. Driectly below this comment // I'm asking the user for the KWH and it just ignores it // when I compile and run. WHY?!? cin &gt;&gt; kwh; } } else if (kwh &gt; 1000) { monthCost = ((kwh - 1000) * 0.45) + 600; } totalCost += monthCost; cout &lt;&lt; "\nYour electric bill for this month " &lt;&lt; monthCount &lt;&lt; " is $" &lt;&lt; monthCost &lt;&lt; ".\n"; cout &lt;&lt; "Would you like to enter another month? (1/0)\n"; cin &gt;&gt; nextMonth; cout &lt;&lt; "\n"; } while (nextMonth == 1); cout &lt;&lt; "\n\nYour total for all " &lt;&lt; nextMonth &lt;&lt; " month(s) is %" &lt;&lt; totalCost &lt;&lt; ".\n"; system("pause"); } </code></pre>

    1. COThere's no `cin << kwh;` in the code; I assume you meant the second `cin >> kwh;` bit?

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.
