类与继承的生命周期

#include <iostream>
#include <fstream>
#include <sstream>
#include <string>
#include <cstdint>

class data
{
public:
    data() { std::cout << "data init~\n"; }
    ~data() { std::cout << "data exit~\n"; }
};

class number
{
public:
    number() { std::cout << "number init~\n"; }
    ~number() { std::cout << "number exit~\n"; }
};

class Base
{
public:
    Base() { std::cout << "Base init\n"; };
    virtual ~Base() { std::cout << "Base exit~\n"; };

private:
    data inter;
};

class worker : public Base
{
public:
    worker() {
        std::cout << "Worker init\n";
    }
    ~worker() {
        std::cout << "Worker exit\n";
    }
private:
    number nm;
};

int main()
{
    { 
        worker aa;
    }
   
    return 0;
}
