Did the File Open?

Write a function bool canOpen(const string& filename) that tries to open the file for reading and returns true if it opened successfully and false otherwise. The starter already creates the ifstream in; return the result of its is_open() member.

The test prints opened when your function returns true and failed when it returns false. The first test passes a file that exists; the second passes the path missing_dir/notes.txt, which cannot be opened. The two tests print, respectively (see Expected Output).

Do NOT write a main function.
