    <p>I am very much a beginner programmer, finishing up Chapter 2 in Starting out with C++ (e7) by Tony Gladdis. I am doing my best to teach myself. Currently I am working on the Challenges at the end of the chapter. The problem I am having is how my output is displaying. With my current code, my output displays my numbers as 54.6293, when I just want it to display 54.62. Can someone please tell me how I can specify in my code to create my desired output?</p> <p>/* Write a program that computes the tax and tip on a restraunt bill for a patron with a $44.50 meal charge. The tax should be 6.75 percent of the meal cost. The tip should be 15 percent of the total after adding the tax. Display the meal cost, tax amount, tip amount, and total bill on the screen*/</p> <pre><code> #include &lt;iostream&gt; using namespace std; int main() { double Meal_Cost = 44.50, Total_After_Tax, Tax_Amount, Total_Bill, Total_Tip; const double TIP = 0.15, MEAL_TAX = 0.0675; // Calculate Tax_Amount Tax_Amount = Meal_Cost * MEAL_TAX; // Calculate Total_After_Tax Total_After_Tax = Tax_Amount + Meal_Cost; // Calculate Total_Tip Total_Tip = Total_After_Tax * TIP; // Calculate Total_Bill Total_Bill = Total_After_Tax + Total_Tip; // Display results cout &lt;&lt; "The meal cost " &lt;&lt; Meal_Cost &lt;&lt; " dollars." &lt;&lt; endl; cout &lt;&lt; "The tax applied to the meal purchase was " &lt;&lt; Tax_Amount &lt;&lt; " dollars." &lt;&lt; endl; cout &lt;&lt; "The tip amount for the purchase was " &lt;&lt; Total_Tip &lt;&lt; " dollars." &lt;&lt; endl; cout &lt;&lt; "The total bill came to " &lt;&lt; Total_Bill &lt;&lt; " dollars." &lt;&lt; endl; system ("PAUSE"); return 0; } </code></pre>

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.
