Is it possible to combine 2 objects of class into one in C++?

#include <vector>
#include <iostream>
using namespace std;
class student
{
  string name;
  int age;
  vector <string> sport;

public:
  student(string name, int age, vector<string> sport):name(name), age(age), sport(sport){}

  string get_name() const { return name; }
  int get_age() const { return age;} const

  vector<string> & get_sport() const { return sport;}

};


int main()
{
  vector<student> v = {
    { "Johh", 13, { "soccer", "cricket" }},
    { "Mitchell", 14, { "cricket" }},
    { "Michael", 13, {"football", "cricket", "soccer"}},
  };

  for (const auto & s : v)
  {
    cout << s.get_name() << ", " << s.get_age();
    for ( const auto & sport : s.get_sport() )
      cout << ", " << sport;
    cout << endl;
  }
}
