Doing a job of assigning names , age , code and note when I try to assign an inheritance to then a setwith AlumnoH, I get an error. I think it may be the way I'm inheriting it but I really don't have much idea, the error says that a '{'(yes, sorry, this error was given to me in the void line StudentH::setValue2(string _name, int _age , string _codigo, float _notafinal) : Person(_name, _age){}, right where it says : Person(_name, _age), exactly in the ':') so that it is correct, but I don't think that is the problem. In an example I saw they didn't need that.

If you could recommend me something to review that part, it would be more than great. Thank you!

inheritance.CPP

#include <iostream>
#include <string>
#include "herencia.h"
using namespace std;


Persona::Persona(){}

void Persona::setValue(string _name, int _age){
    this-> name = _name;
    this-> age = _age;
}
const string Persona::getName() const{
    return name;
}
const int Persona::getAge() const{
    return age;
}

void AlumnoH::setValue2(string _name, int _age, string _codigo, float _notafinal) : Persona(_name, _age){
    this-> codigo = _codigo;
    this-> notafinal = _notafinal;
}


Persona::~Persona(){}

inheritance.h

#include <iostream>
#include <string>
using namespace std;

class Persona{
private:
    string name;
    int age;
public:
    Persona();
    virtual ~Persona();
    Persona(string, int);
    virtual ~Persona();
    void setValue(string _name, int _age);
    const string getName() const;
    const int getAge() const;
};

class AlumnoH : public Persona{
private: 
    string codigo;
    float notafinal;
public:
    AlumnoH();
    virtual ~AlumnoH();
    
    void setValue2(string, int, string, float) : Persona(string, int);
    const string getName() const;
    const int getAge() const;
    const string getCodigo() const;
    const float getNotafinal() const;
};

main.cpp

#include <iostream>
#include "herencia.h"
using namespace std;

template<typename T>

void print(T objeto){
    cout << objeto.getName() << endl;
    cout << objeto.getAge() << endl;
}


int main(){
    Persona P1;
    P1.setValue("Hernan", 12);
    print(P1);
}

I need to know how to make a list of lists, something like in python and dictionaries, where they gave you an entry and returned the values. In other examples, something like creating a list of students and each student having their average A and their average B. (Student -- [average A , average B]. With that data then, based on user input, print the value and either averageA or averageB. An input like:
input:
Student: Pedro

Output:
AverageA: 15
AverageB: 17

From my program I tried doing this but it only gives me an error.

#include <iostream>
#include <iomanip>
using namespace std;

void azar(int planetas[]){

}
int main(){
    int planetas; int Mercurio[2] = {0.5, 0.3};
    int** sistema = new int*[planetas]; 
    for(int i = 0; i < 4; i++){
        for(int j = 0; j < 4; j++){
            sistema[i][j] = Mercurio;
            cout << sistema[i][j];
        }
    }
}

This is basically the problem, I want to repeat a string several times without using a lot of space, that's why I say without using a for.
