Default values for array arguments

Question

Just playing around a little with C++. What I really want to do is to be able to setup a function with default values defined for an array or pointer argument. To keep thing

Answer 1

A default parameter must be valid.

You can call

f("abc")

but never

f({'a','b','c'});

"abc" is effectively an address in memory and {'a','b','c'} means initialise an array or struct/class.
