Re: using yacc union in managed c++

Is there a way to implement the union in a managed c++ yacc parser?
visual studio compiler complains about the union, so for strings i
created an array and returned the index of the string via yylval. but
i need to return operators, floating point numbers, etc. and this
seems klutzy. got any better ideas?

There are basically two choices -- you either ensure that the union is
a valid POD type (all the fields are types that don't have constructors or
destructors), or you can not use the %union directive at all and instead
#define YYSTYPE to be some non-union type (usually some kind of smart
pointer type).
