title: Using multiple .cpp files in c++ program?
body: <p>I recently moved from Java for C++ but now when I am writing my application I'm not interested in writing everything of the code in the main function I want in main function to call another function but this other function is in another .cpp file.</p>
  
  <p>Let me explain better if you wouldn't understand:<br>
  I have one file: <code>main.cpp</code> inside it I have main function.</p>
  
  <p>I have the second file: <code>second.cpp</code> inside I have a function called <code>second()</code> I want to call this function called <code>second()</code> from my main function..</p>
  
  <p>Any help?</p>
