Есть 2 класса:
1-й:
Код:
//polygon.h
#ifndef polygon_h
#define polygon_h
#include "coordinate.h"
class polygon
{
public:
polygon();
polygon(unsigned amount,coordinate x_temp, coordinate y_temp);
virtual ~polygon();
bool square(double& s);
friend std::istream& operator>>(std::istream& is,polygon& object);
protected:
virtual bool isEnter() const;
virtual double calculationSquare();
private:

};
inline polygon::polygon()
{
isEnterVar=false;
}
inline bool polygon::isEnter() const
{
return isEnterVar;
}
inline polygon::~polygon()
{
}
#endif
Код:
//polygon.cpp
#include "polygon.h"
#include <iostream>
#include <math.h>
using namespace std;
//....

for(unsigned i=0;i<object.number;++i)
{

}
object.isEnterVar=true;
return is;
}
//....
2-й:
Код:
//rectangle.h
#ifndef rectangle_h
#define rectangle_h
#include "coordinate.h"
#include "polygon.h"
class rectangle: public polygon

inline rectangle::rectangle():polygon()
{

}
inline bool rectangle::isEnter() const

inline rectangle::~rectangle()

#endif
Код:
//rectangle.cpp
#include "rectangle.h"
#include <math.h>
//...
std::istream& operator>>(std::istream& is,rectangle& object)
{
object.x.resize(2);
object.y.resize(2);
for(unsigned i=0;i<2;++i)
{
is >> object.x[i] >> object.y[i]; //здесь ругается!
}
object.isEnterVar=true;
return is;
}
//...
Перегружаю оператор >>. Для 1-го класса не ругается, а для 2-го ругается: ошибка: no match for ‘operator>>’ in ‘is >> object->rectangle::x.std::vector<_Tp, _Alloc>::operator[] [with _Tp = double, _Alloc = std::allocator<double>](i)’
Вот вектор:
Код:
//coordinate.h
#ifndef coordinate_h
#define coordinate_h
#include <vector>
typedef std::vector<double> coordinate;
#endif
Никак не пойму ошибку
