I need some help figuring out how to remove duplicates from an array. I've been working on this for a few days now, and every time I think I'm getting close, it just causes my program to shut down.
I've gt a text file with city names in it and mileage distances between the cities. But the cities are listed more than once. So out of 4 cities, I currently have an array with 12 elements. I need to remove the duplicates.
I'm not asking for someone to write the code for me... Just a little help on how to go about ignoring/removing the duplicates, so that I can end up with an array of just 4 unique city names. I'm still pretty new at this, sorry if this is a really basic question.
Thanks a lot, for any help!
