    <p>I cannot for the life of me figure out what is wrong with these simple equations I have in putty. I think everything is set up right, but my output is wrong from my professors sample output by a slight degree.</p> <pre><code>//This program is used to calculate total cost of painting. #include &lt;iostream&gt; #include &lt;iomanip&gt; using namespace std; //These are the function prototypes that will be used for the main function. void displayInstructions(int &amp;feet, float &amp;price); float paintprice (int feet, float price); float laborprice (int feet); float totalcost(float paint, float labor); void displayoutput (float paint, float labor, float total, int feet); int main() { int feet=0; float price=0; float paint=0; float labor=0; float total=0; displayInstructions(feet, paint); paint=paintprice(feet, paint); labor=laborprice(feet); total=totalcost(labor, paint); displayoutput(paint, labor, total, feet); return 0; } void displayInstructions(int &amp;feet, float &amp;price) { cout&lt;&lt;setw(35)&lt;&lt;"==================================="&lt;&lt;endl; cout&lt;&lt;setw(30)&lt;&lt;"Painting Cost Calculator" &lt;&lt;endl; cout&lt;&lt;setw(35)&lt;&lt;"===================================" &lt;&lt;endl; cout&lt;&lt;"This program will compute the costs (paint, labor, total)\nbased on th\ e square feet of wall space to be painted \ and \nthe price of paint." &lt;&lt;endl; cout&lt;&lt;"How much wall space, in square feet, is going to be painted?" &lt;&lt;endl; cin&gt;&gt;feet; cout&lt;&lt;"How much is the price of a gallon of paint?" &lt;&lt;endl; cin&gt;&gt;price; } float paintprice (int feet, float price) { float paint; paint=((feet/115)*price); return paint; } float laborprice (int feet) { float labor; labor=((feet/115)*18*8); return labor; } float totalcost (float paint, float labor) { float total; total=(paint+labor); return total; } void displayoutput (float paint, float labor, float total, int feet) { cout&lt;&lt;"Square feet:" &lt;&lt;feet &lt;&lt;endl; cout&lt;&lt;"Paint cost:" &lt;&lt;paint &lt;&lt;endl; cout&lt;&lt;"Labor cost:" &lt;&lt;labor &lt;&lt;endl; cout&lt;&lt;"Total cost:" &lt;&lt;total &lt;&lt;endl; } </code></pre> <p>based on the input being feet=12900, and price=12.00 The final output for the cost of paint should be $1346.09 The final output for the cost of labor should be $16153.04</p> <p>I get respectively: $1344.00, $16128.00</p> <p>if you can help me out it would be a life saver.</p>

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.
