Class Basics

[perto1]

Hi, I am a first semester student, learning the OOPs basics. I need help for a program:

class Message{
public:
    void input();
    int output();
private:
    long token_number;// next token to be given to client
 
};
 
void Message::input()
{
    token_number = 1;
}
 
int Message::output()
{
    return token_number;
}
 

I dont know the right way to call these elements in the main()

int main(){
Message obj;
 
std::cout<< out_buffer<<obj.output()<<std::endl;//write the token number in the buffer
std::cout<<"Response received"<<++obj.input();//To update the input value and display
}
 

[dev7060]

int main(){
Message obj;
 
std::cout<< out_buffer<<obj.output()<<std::endl;//write the token number in the buffer
std::cout<<"Response received"<<++obj.input();//To update the input value and display
}

What are you trying to do?

You might be looking for

int main() {
  Message obj;
  obj.input();
  std::cout << obj.output();
  return 0;
}

• A member function can be used to update the private data members.
• A constructor is used to initialize the object.
