C++ can be so sexy:

vector< vector<int> >formula;

vector<int> clause; clause.push_back(1); clause.push_back(-2); formula. push_back(clause);

clause.clear(); clause.push_back(-1); clause.push_back(2);

formula. push_back(clause);

And C++11 can even be short:

vector<vector<int>> formula = { { 1, -2 }, { -1, 2 } };

Or you can offer a little loader framework: namespace _detail { template<class _C> class _Loader; } template<class _C> _detail::_Loader<_C> load( _C & f ) { return _detail::_Loader<_C>( f ); } Provide a specialized formula loader: namespace _detail { template<> class _Loader<vector< vector<int> > > { public: _Loader( vector< vector<int> > & f ) : _f( &f ) {} _Loader & operator()( int l, int r ) { vector<int> clause; clause.push_back(l); clause.push_back(r); _f->push_back(clause); return *this; } private: vector< vector<int> > * _f; }; } So you can simply write: vector< vector<int> > formula; load(formula)(1,2)(-1,2); Beauty is in the eye of the beholder. -- cu, Michael Andres +------------------------------------------------------------------+ Key fingerprint = 2DFA 5D73 18B1 E7EF A862 27AC 3FB8 9E3A 27C6 B0E4 +------------------------------------------------------------------+ Michael Andres SUSE LINUX Products GmbH, Development, ma@suse.de GF:Jeff Hawn,Jennifer Guild,Felix Imendörffer, HRB16746(AG Nürnberg) Maxfeldstrasse 5, D-90409 Nuernberg, Germany, ++49 (0)911 - 740 53-0 +------------------------------------------------------------------+ -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org
