Calling external code in C++ program???

[southtucky]

I'm new to C++, but I've been a PHP programmer for years. I've searched all over, and can't seem to find an example of how I might do this code in C++. Forgive me for my ignorance.

PHP:

<?php
a=10;
b=20;
if((a+b)==30){
include("message.php");
}
else{
include("alternativemessage.php");
}
?>

The problem is with the includes. How can I include external code to be executed with my console application file in C++?

Any help is greatly appreciated.
