inistializing derived class veriables

Sorry if my terminology is off, it's been a long while since i've practiced programming.

Code:

---

#include <iostream>
#include <string>
using namespace std;
class parent{
protected:
    int age;
public:
//setter
    void setValue(int age) { age=age; }
    parent(int);
//getter
    int getAge() { return age; }
//methods
    void talk() { cout<<"I am the parent, shuttup a your face! "<<endl; }
};
class son:public parent{
private:
    int number;
public:
 
};
parent::parent(int age){
    this->age=age;
};
int main () {

parent dad(45);
 

}

i am trying to initialize the variable in the derived class son, i can't find a way and i have been mashing it out for a few hours now, can someone please tell me how, thanks in advance!

is the main methods for storing and retrieving DATA in private class variables using setter/getter methods? is this common practice?

Code:

---

#include <iostream>
#include <string>
using namespace std;
class parent{
protected:
int age;
public:
//setter
void setValues(int Age) { age=Age; }
//getter
int getAge() { return age; }
//methods
void talk() { cout<<"I am the parent, shuttup a your face! "<<endl; }

};
class son:public parent{
private:
int number;
public:
void talk() { cout<<"Hi my name in John, i am the son. "<<endl; }
son(int a) { number = a; }
};

int main () {

son john(0);

}

Ok i figured it out and it makes sense to me now but i'll have to play around with this method for a few days just to let the whole process sink in, thank guys! :biggrin:
