PS 1 A short problem sheet this week!

1. In a terminal type emacs Hello.cpp & to open a new file and type into it the hello world programme:

   #include
   #include
   
   using namespace std;
   
   int main()
   {
   	cout<<"Someone must have been spreading false rumors"<<endl;
   }
   

   Save it using ^x^s and in the terminal window compile it using g++ Hello.cpp and run it using ./a.out. If you would prefer to use a different editor, that's fine. You can close emacs with ^x^c. Play around with emacs and the programe a bit, for example, try

   	cout<<"Someone must have been spreading false rumors\n";
   

   instead. What is the role of the \n?
