[prog] structures containing structures 2

[sena emre]

Hi Tim,
   
  Thanks for your help. You are true, I am a beginner. But I think that I am not to bad....:) Anyway I just did not understand that part;
   
  solution_t& solution = solutions[idx_solution];
   
  box_t box = solution.cargoes[idx_cargo];

why did you use &  operator for the first definition? more, why we defined box of type box_t instead of cargos of type box_t? Because we defined cargos of type box_t under solution_t.
   
  Also another point  is that how should I pass a structure to a function? Is this function prototype declaration suitable for this purpose?
   
  void pass( struct solution_t solution);
   
  one last question is ...:)  Sometimes I get across to code like this...
   
  solution_t *solution = NULL; 
   
  what this line tells to the compiler....
   
  thanks again...
