Swap

Prototype:

    # Include <string>  
   Void  Swap (  String  &  From  )  ; 

The swap () function replaces the elements of the current string and from. This function uses constant time (Constant time) Run. For example, the followingCodeSwap () is used to exchange the values of two strings:

    String  First (     "This comes first"     )  ;
    String  Second  (     "And this is second"    )  ;  
First.  Swap  (  Second )  ;
     Cout     < First  <  Endl  ;
     Cout    <  Second  <  Endl  ; 

The code will generate the following output:

And this is second this comes first
