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.swap( second ); // 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
