\index{default(none) clause@\kcode{default(none)} clause}

The following example distinguishes the variables that are affected by the \kcode{default(none)} 
clause from those that are not. 

\begin{ccppspecific}
Beginning with OpenMP 4.0, variables with \bcode{const}-qualified type and no mutable member 
are no longer predetermined shared.  Thus, these variables (variable \ucode{c} in the example) 
need to be explicitly listed
in data-sharing attribute clauses when the \kcode{default(none)} clause is specified.
