  const T &var = expression;

The initialization of var in a real, but simple context.

A similar program that initializes a user defined struct via a 'functional casting' constructor.

An envelope around the stdlib div function that returns a struct of quotient and remainder.

Ways of returning results from the div function

A similar setup - illustrates that it is not good to return a reference to a deallocated local variable.
