Как вывести имена файлов с контейнера?

#include <iostream>
#include <vector>
#include <string>
 
class object {
    int m_i;
public:
    object( int i ) : m_i(i) {}
    friend std::ostream &operator <<(std::ostream &os, const object &o);
};
 
std::ostream &operator <<(std::ostream &os, const object &o) {
    return os << o.m_i; 
}
 
class my_container : public std::vector < std::pair <std::string, object *> > {
public:
    my_container( std::string s, object *op ) : std::vector < std::pair <std::string, object *> > ( 1, std::pair <std::string, object *> ( s, op ) ) {}
};

my_container a(name, new object(index));

    
my_container a;
textBox1->Text = a.back();

#include <iostream>
#include <vector>
#include <string>
 
class object {
    int m_i;
public:
    object( int i ) : m_i(i) {}
    
};
 
 
class my_container : public std::vector < std::pair <std::string, object *> > {
public:
    my_container( std::string s, object *op ) : std::vector < std::pair <std::string, object *> > ( 1, std::pair <std::string, object *> ( s, op ) ) {}
};
