C++ general log file, that follow a program full of classes
<p>I got a program with about 3-7 classes:</p>

<pre><code>Class A
Class B
Class C
</code></pre>

<p>i got another file lets call it Run.cpp where the main sits in.</p>

<p>the problem is that in class A and B and C and also in my main. i want to write my program progress into a log file, like,  - <em>Jhony the turtle walked 20 meters. etc...</em></p>

<p>i want to do it without having to send the file to the classes methods.</p>
