Here is the full code (its fairly short):

/* Proxy Main Logic */
/* Method Main */
int main()
{
string destination;
string source = "/mnt/TrafficKing";
cout<<"Preparing to install Train TrafficKing..." << "/n" << "You must
have root privileges to install this game." << "/n" << "If you do NOT
have root privileges, please contact your System Administrator." << "/

What follows is not a class:
class A
{
}
But this is:
class A
{
};
You should
#include <string>
if you plan to use std::string and pass it by reference to functions
or you'll end up invoking std::string copy ctor unneccessarily. Not to
mention that you'ld be modifying a local only.
void foo( std::string& r_s ) // or const std::string&
{
// do stuff with r_s
}
All of the above is basic, fundamental, unavoidable, required
knowledge.
What book are you reading?
