vector<ifstream*> 과 같이 사용하면 괜춘!

1. #include <iostream>
2. #include <string>
3. #include <vector>
4. #include <fstream>
5. using namespace std;
7. void foo(ifstream& in)
8. {
10. }
12. int main()
13. {
14. vector<ifstream*> streams;
15. for(size_t i = 0; i < 5; i++)
16. {
17. ifstream* in = new ifstream;
18. streams.push_back(in);
19. streams[i]->open("filename.txt");
20. }
21. foo( *streams[1] );
22. }
