help! what's wrong with this class & it's functions/calls?

[GPXtC02]

New to classes. Getting alot of errors when calling the private member variables (from down in main). Most are telling me either i can't access the private member variable IDs or the other member variables i'm attempting to access (debit, credit, balance) are undefined ('identifier not found'). Also getting 'overloaded member function' errors for just about each function. Help please?

Most are telling me either i can't access the private member variable IDs or the other member variables i'm attempting to access

private means just exactly that -- only the class itself can access private members. Work around: write get() and put() public methods to make private members available outside the class

class CorporateClass {
public:
    CorporateClass(int I): ID(I) { }//contstructor method
    CorporateClass(){} //constructor method

    void initialize(ifstream text, float &, float &, float &);
    void div_update(float, float, float);
    void add_credit(ifstream text, float &, float &);
    void ded_debit(ifstream text, float &, float &);
    void HQset();

// get methods
    int getID() { return ID; }
    // etc for all other private members you want to
    // give public access

// put methods
    void putID(int id) {this->ID = id;}
// etc for others

private:
    int ID; //4 digit int values
    float balance;
    float credit;
    float debit;
};

Now you can use the put() and get() methods in main

appreciate it.
