One can give an example of how to create the main, the . h, and the . cpp in c++? and also connect them all. For example, having a function that receives an input value a, having another class that receives input a b and a separate class do the sum and return to main. I’m new to this language.

    Is there any way to put in the question the code you tried to do? This way we can better see which parts you are struggling with. I would add that a "I don’t know how to start" response is a good sign that you should review the basics before trying something like what you’re doing. Maybe review the contents of building algorithms and re-read the material on C syntax++.

Include default for language use

#include <iostream>

using standard for language use

using namespace std;

Creating a class Acampamentos

class Acampamentos{
public:
    int idade;
    string nome;
    char equipe;

    Acampamentos();
    void imprimir();
    void separarGrupo();
};

Default format of the constructor

Acampamentos::Acampamentos(){

    idade =0;
    nome = " ";
    equipe = ' ';
}

Creating a function imprimir() only to print class attributes on the console

void Acampamentos::imprimir(){
    cout << "Idade .: " << idade << endl;
    cout << "Nome ..: " << nome << endl;
    cout << "Equipe : " << equipe << endl;
}

Way to print on console
cout << "String desejada" << Concatenate with the desired attribute << endl
Ndle skips line at the end of writing on the console (End Line)

Creating a function seperarGrupo where sets the team by age

void Acampamentos::separarGrupo(){

    if(idade >=6 && idade <= 10){
        equipe = 'A';
    }

    if(idade > 10 && idade <= 20){
        equipe = 'B';
    }

    if(idade >20){
        equipe = 'C';
    }
}

Creating the main

int main(int argc, char** argv) {
    Acampamentos A;

    cout << "Escreva o nome : ";
    cin >> A.nome;
    cout << endl;
    cout << "Digite a idade :";
    cin >> A.idade;
    cout << endl;
    system("cls");
    A.imprimir();
    system("cls");
    A.separarGrupo();
    A.imprimir();
    return 0;
}

To receive an input and assign to another variable cin >> Atributo desejado . If you are in a class, use the instance Instancia.atributo_desejado
