c++ - expected unqualified id before "." token

Question

I've been reading a book called c++ for dummies (7th edition) and I'm currently going through the chapter about classes. I decided to try and write my own program using classes and it looked easier than I found it. I'm having this persistent problem ('expected unqualified id before "." token) that hasn't gone away with the fixes I've tried. It seems this question is program specific so I'm fine with it getting shutdown for only being helpful to me. Here's the code:

class savings {
public:
    void Set_Pin(double pin) {
      savings.pin = pin; // this is where the error is
    }
private:
    int pin;
    int username;
};

how do I fix the error? thanks

Answer 1

You need to use this i.e.

change

 savings.pin = pin;

to

 this->pin = pin;
