Class Inheritance

Attention: I figured it out. I forgot to change A to be c instead when I was messing around with my classes.

I'm trying to figure out how to link classes by inheritance but I keep getting an error:

Code:

Line 41 | error: expected unqualified-id before '-' token

Here is my sample code:

Edit: Forgot to include the methods for set, so I included those as well.

Code:

#include <iostream>

#define CONTACTS 50

using namespace std;

class A {
    private:
        string name[CONTACTS];
    public:
        void set_name(string, int);
        string get_name(int x){return name[x];}
};

void A::set_name(string s, int x){name[x] = s;}

class B: public A {
    private:
        string number[CONTACTS];
    public:
        void set_number(string, int);
        string get_number(int x){return number[x];}
};

void B::set_number(string s, int x){number[x] = s;}

class C: public B {
    private:
        string email[CONTACTS];
    public:
        void set_email(string, int);
        string get_email(int x){return email[x];}
};

void C::set_email(string s, int x){email[x] = s;}

int main(){
    C c;
    int index = 0;

    c.set_name("First Last", index);
    c.set_number("1-234-567-8901", index);
    c.set_email("first.last@gmail.com", index);
    cout << c.get_name(index) << endl;
    cout << c.get_number(index) << endl;
    cout << c.get_email(index) << endl;

    return 0;
}

I don't see a '-' token in your code. There are '-' characters, but they are part of a string literal.

That's why I was confused. I figured it out by changing

Code:

A.set_name("First Last"), index);

to

Code:

c.set_name("First Last"), index);

Well, I don't see A.set_name in your original code either. The error should have been "expected unqualified-id before '.' token" in that case.

Your brackets don't line up in those statements.
