    <p>my homework assignment is to create a class named Currency, using integers as the primitive type for dollars. And I must use these public methods I have..... Now I removed the "cents" part, and the "subtration" part, because I'm assuming I can do those once I figure out how to do "Addition" for "Dollars" currency type.</p> <p>No matter what I put into the "Currency Add(int Dollars);" I cannot get my code to work =. I've done things like totalDollars += Dollars, return totalDollars, or just Dollars += Dollars, etc.</p> <p>The output is always garbage : "-8353513636". Or sometimes whatever number I put in the constructor.</p> <p>I just can not seem to get it to PASS the number in and keep it there (Eventually want to make it hold a running total), and output it when I'm done. I've shortened up my code because the only problem with my code is the parts dealing with the "class"/currency data type. It just won't work.</p> <p>At one point it told me it cannot convert from int to Currency data type</p> <p>Here's the code I have so far:</p> <pre><code>/* Program By: Date: 4/29/2011 Class: */ #include &lt;iostream&gt; #include &lt;iomanip&gt; #include &lt;fstream&gt; #include &lt;cstring&gt; #include &lt;cstdlib&gt; #include &lt;cctype&gt; #include &lt;cmath&gt; #include &lt;ostream&gt; using namespace std; // Currency Class class Currency { private: int Dollars; public: Currency(); Currency(int Dollars); Currency Add(int Dollars); int GetDollars(); }; Currency::Currency() { Dollars = 0; } Currency::Currency(int Dollars) { } // Add Currency Currency::Add(int Dollars) { // Have put totalDollars += Dollars, etc. // Have also put a "return" value here. } int Currency::GetDollars() { return Dollars; } int main() { Currency payroll; int currDollars; cout &lt;&lt; "Please enter a dollar mount" &lt;&lt; endl; cin &gt;&gt; currDollars; payroll.Add(currDollars); cout &lt;&lt; "Current Amount is: " &lt;&lt; payroll.GetDollars() &lt;&lt; endl; return 0; } </code></pre> <p>What am I doing wrong? I've been at this for several hours and I need to have it in by tomorrow =. Help MUCH APPRECIATED!!!!</p>

    1. COA few comments on style. It's better to use member initialization in the constructor, like `Currency::Currency(int Dollars) : Dollars(Dollars) {}`. And it'd be better to get rid of your default constructor and just use the `int` constructor with a default argument of 0. That would make the declaration in the class `Currency(int Dollars = 0);`

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.
