I need help with a program

zainkool (2)
I am stuck at trying to loop information of a file that includes cities and their latitude and longitude into a structure array. My structure is called Place and has member variables are string city, int latitude, and int longitude. I'm trying to loop the file which is included in the command line, but I can't get it to work. Where am I doing it wrong? can someone give me a hint as to why it not working?

You should declare your structs earlier than the loop. So move Place location[4]; up to line 31.

Also, instead of (fin.good()), I like to use (!fin.eof()) to loop while it is not the end of the infile. That's just me though.
