Class is undefined
<p>I have two classes, one called <code>Grocery</code> and the other one called <code>Strings</code></p>

<p>In the <em>Grocery.cpp</em> I'm trying to use a function from the "Strings" class called : "copyString" and I get the following error:</p>

<blockquote>
  <p>identifier "copyString" is undefined</p>
</blockquote>

<p>The "Strings" class is just a generic Class for the base string function such as : strcmp, strcpy and so on....</p>

<p>In the "Grocery" class I don't want to create a "Strings" object but using It like a the "Math" class is being used in C#. Just indicating the class name and using a dot to call a function of the Class.</p>

<p>How can I create a class "Strings" with the same functionality as the "Math" class in C# I described above?</p>

<p>Thanks a lot!
Guy</p>
