Given the following function,

char$*$ GetString$($std::istream& is$)\{$

char str$[255]$;

is $>>$ str;

return str;

$\}$

what's wrong with GetString's definition?

A pointer to an array cannot be returned by any function.

An array's name can never be used to initialize a pointer.

The address of stack memory associated with a local variable is returned.

The return type must be char& instead of char$*$ for GetString to compile.
