Hi,

 

BOOST_PP_CAT( MACRO1, MACRO2 );

 

MACRO1 expands to double

MACRO2 expands to x

 

BOOST_PP_CAT( MACRO1, MACRO2 ); therefore expands to        doublex;

 

I am trying to get the statement

 

double x;

 

I couldn't find any macro that expands to whitespace?

I am missing something obvious here

 

Regards,
