Structure Reference (cont.)

• as demonstrated in strtref.cpp, since use returns a reference, this reference can be on the left side of an assignment.

  • use ( looper ) = morf;

• same as

  • use ( looper );
  • looper = morf;

• I believe the second way is more readable and just about as easy to code.

• This only works if the function returns a reference to a data object or variable.
