public :
    A() : _myValue(0) {};
 
    A& IncrVarTen()
    {
        _myValue += 10;
        cout << "value is:" << _myValue << endl;
        return *this;
    }
 
    A& IncrVarTwenty()
    {
        _myValue += 20;
        cout << "value is:" << _myValue << endl;
        return *this;
    }
 
    int _myValue;
};
 
 
int main()
{
    A a;
    a.IncrVarTen().IncrVarTwenty();
    cout << "Final value is:" << a._myValue << endl;
    return 0;
}
