Whats wrong with my C++ syntax here
<pre><code>while input != 0
    { 
        if input == "r";
        cout &lt;&lt; "Please input a floating point value for the height, and then a floating point value for the width, seperated by a comma." &lt;&lt; endl;
        cin  &gt;&gt; height &gt;&gt; width;
    }
</code></pre>

<p>I am trying to write a basic program that takes the dimensions of basic shapes and outputs the  area.  This is what I am starting with, but I am not sure what is wrong with this syntax.  Could someone help?</p>
