[Qt-interest] struct & class

[navid navid]

Hello All,

Because of unavailability of operator == or != for structure comparison, I had to change {struct of variables} to {class of variables with operator definition}.  
but now, the functions that returned SETPOINT, can't return SetPoint; and show  "error: `SetPoint' does not name a type"

struct SETPOINT 
{
         double a;
         int b;
         double c;
         int d;};

class SetPoint 
{
         public:
          double a;
          int b;
          double c;
          int d;
          bool operator!=(SetPoint other)
          {
               return ((a!=other.a)      ||
              (b!=other.b)||
              (c!=other.c)        ||
              (d!=other.d));
          }
};


what is solution?
