Does a file will be global if its objected is created globally but opened in main or any other function?

Question

#include <fstream>

using namespace std;

ifstream fin;

int main(){
fin.open("test.txt",ios::in|ios::binary);
....
}

In the above code if the file opened is global (can it be use globally or not).

Answer 1

Yes. It will be accessable file fin (P.S. don't forget to close it)
