Operator cin overload

[Lio]

If my variables are public the operator cin works no problem,but if they are private it doesnt work.I try to fix the problem with set functions ,but still doesnt work
Thanks

#include <iostream>
using namespace std;
class MyClass
{
public:
    MyClass()  :  varI(0),varF(0) {}
    MyClass(int i,float f): varI(i),varF(f) {}
    int getVarI()           {  return varI;  }
    float getVarF()         {  return varF;  }
     void setVarI(int i)     {varI=i;}
    void setVarF(float f)   {varF=f;}
private:
    int varI;
    float varF;
};
ostream& operator<<(ostream& out,MyClass & o)
{
    out<<o.getVarI()<<"-"<<o.getVarF()<<endl;
    return out;
}
istream& operator>>(istream &input,MyClass &o)
{
    input>>o.setVarI(o.varI);
    input>>o.setVarF(o.varF);
    return input;
}

int main()
{
    MyClass o1(2,33.3);
    cout<<o1;
    MyClass o2;
    cout<<"Enter int and float: ";
    cin>>o2;
    cout<<"The entered numbers are: ";
    cout<<o2;

}

i don't really know about this too, but as far as i know, the overloaded functions is not your class' member function, it should be:

class MyClass
{
public:
    MyClass()  :  varI(0),varF(0) {}
    MyClass(int i,float f): varI(i),varF(f) {}
    int getVarI()           {  return varI;  }
    float getVarF()         {  return varF;  }
     void setVarI(int i)     {varI=i;}
    void setVarF(float f)   {varF=f;}
    friend istream& operator >> (istream & input, MyClass& o);
private:
    int varI;
    float varF;
};

Thanks,with friend and accessint the variables directly work
Is there way to set the variables with set functions

[chipp]

what do you mean set the variable? i thought, by making a member function, you already know how to use them...

//define outside the class
void MyClass::setVarI(int i) {
   varI = i;
}

hope helps...

istream& operator>>(istream &input,MyClass &o)
{
    int i ;
    float f ;
    input >> i >> f;
    o.setVarI(i) ;
    o.setVar(f) ;
    return input;
}

cin is not an operator, it's an object of class istream. You would need to overload the >> operator
