error expected unqualified-id before token struct

Question

I need to make a program that gets a fraction from the user and then simplifies it   I know how to do it and have done most of the code but I keep getting this error  error  expected unqualified-id before         token    I have declared a struct called ReducedForm which holds the simplified numerator and denominator  now what Im trying to do is send the simplified values to this struct  Here is my code   In Rational h    ifndef RATIONAL H  define RATIONAL H  using namespace std   struct ReducedForm       int iSimplifiedNumerator      int iSimplifiedDenominator        I have a class here for the other stuff in the program  endif   In Rational cpp    include  lt iostream gt    include  rational h   using namespace std   void Rational    SetToReducedForm int iNumerator  int iDenominator    int iGreatCommDivisor   0   iGreatCommDivisor   GCD iNumerator  iDenominator      The next 2 lines is where i get the error ReducedForm iSimplifiedNumerator   iNumerator iGreatCommDivisor  ReducedForm iSimplifiedDenominator   iDenominator iGreatCommDivisor

The struct s name is ReducedForm  you need to make an object  instance of the struct or class  and use that  Do this   ReducedForm MyReducedForm  MyReducedForm iSimplifiedNumerator   iNumerator iGreatCommDivisor  MyReducedForm iSimplifiedDenominator   iDenominator iGreatCommDivisor

You are trying to access the struct statically with a   instead of     nor are its members static  Either instantiate ReducedForm   ReducedForm rf  rf iSimplifiedNumerator   5    or change the members to static like this   struct ReducedForm       static int iSimplifiedNumerator      static int iSimplifiedDenominator       In the latter case  you must access the members with    instead of   I highly doubt however that the latter is what you are going for

ReducedForm is a type  so you cannot say  ReducedForm iSimplifiedNumerator   iNumerator iGreatCommDivisor    You can only use the   operator on an instance   ReducedForm rf  rf iSimplifiedNumerator   iNumerator iGreatCommDivisor
