Answer 1

2) /*
This program demos void functions using
  value parameters vs. reference parameters

Reference Parameter:
If a formal parameter is a reference parameter, it
receives the address of the corresponding actual
parameter

A reference parameter stores the address of the
corresponding actual parameter

During program execution to manipulate the data,
the address stored in the reference parameter directs
it to the memory space of the corresponding actual
parameter
