2. Passing parameters by value

• As written, the normalize() function

  
      void normalize( Rectangle rect )
      {
          rect.set_dimensions( 1, 1 );
      }
  
  

  has no effect on the rectangle declared in main().

• By default, in C/C++ the parameters are always passed by value:

  1. a copy of the original object is made before the function is called

  2. the called function works with the copy of the object

  3. the copy is destroyed

  4. the function returns

  5. the original object is never modified
