It should run.. just the IDE you are using (or if none) doesn't pause the program at the end to let you see the final output. You can find a long, long, thread about this here - http://www.cplusplus.com/forum/beginner/1988/
Hi,Regine
I think a "<<" is missed in line 9.
That means << "15.0 divided by 2.0 equals " (15.0 / 2.0) << endl ;
should be << "15.0 divided by 2.0 equals "<< (15.0 / 2.0) << endl ;
