c ++：类X没有名为Y的成员

Question

I´ve got this CRac class and it´s giving me some problems with its members.

//Definition TAD CRac.hpp

#ifndef CRAC_H
#define CRAC_H

namespace bblRac{

struct Racional{
    int num, denom;
};  

class CRac{
public:
    CRac();
    void read();
    void asignarVal (const CRac& otroRac);
    void write();
    void add(const CRac& otroRac)const;
private:
    Racional rac;
    void simplif();

}; //End of class CRac
} //End of namespace bblrac

#endif

In a ccp file I have

#include "CRac.hpp"
using namespace bblRac;

void CRac::add(const CRac& otroRac)const{
    CRac res;
    res.num= rac.num + otroRac.num; //line 98
    res.denom= rac.denom + otroRac.denom;
}

And when I run it, the output is

CRac.cpp:98: error: ‘class bblRac::CRac’ has no member named ‘num’
CRac.cpp:98: error: ‘const class bblRac::CRac’ has no member named ‘num’
CRac.cpp:99: error: ‘class bblRac::CRac’ has no member named ‘denom’
CRac.cpp:99: error: ‘const class bblRac::CRac’ has no member named ‘denom’

I have tried to fix it with the pointer this, but it continues giving the same mistake.. Thank you!

Answer 1

This will fix it.

#include "CRac.hpp"
using namespace bblRac;

void CRac::add(const CRac& otroRac)const{
    CRac res;
    res.rac.num= rac.num + otroRac.rac.num; //line 98
    res.rac.denom= rac.denom + otroRac.rac.denom;
}

Your CRac class contains a Racional member variable, num and denom are not members of CRac .

Answer 2

res.rac.num = whatever;
otroRac.rac.num = whatever;
