15.24.1.Using string.swap function to swap two strings
#include <iostream>
using std::cout;
using std::endl;

#include <string>
using std::string;

int main()
{
   string first"one" )
   string second"two" );

   cout << "Before swap:\n first: " << first << "\nsecond: " << second;

   first.swapsecond )// swap strings

   cout << "\n\nAfter swap:\n first: " << first
      << "\nsecond: " << second << endl;
   return 0;
}
Before swap:
 first: one
second: two

After swap:
 first: two
second: one
