//  I read from the net that the new C++ should support foreach loops
//  similar to those in Java.

//  I tried to make this program, but my compiler is old.

//  In the end the program showed very strange behaviour.

#include  <iostream>
#include  <string>    // class string etc.
#include  <vector>
