One alternative is to put the read string into a map. Once you do this, go and read the next string from the file. If this string exists in the map ignore it and do not put it in the map and so on. While displaying, display only the elements present in the map. Hope it helps

You need to google first, if you have "It's urgent please" mentioned in your question. ;-)_AnShUmAn_

Read line by line into an STL list class and call the unique method. Call the sort method before unique if the data is not already sorted.

Hello rdop, You can use std::set to remove duplicate entries. This link will be useful - link[^]. Regards, Jijo.
