Word Count Demo

This simple demo uses an unordered map to count the number of occurrences of each word in a text file. The words and their counts are then copied to a vector of pairs, and the vector is sorted by the number of occurrences in descending order, to produce a list of the most frequently used words.

How to

After cloning or downloading the repository, you can build and run the demo with the following commands:

$ cd wordcount-demo
$ g++ -std=c++17 wordcount.cpp -o wordcount
$ ./wordcount
Enter filename: getty.txt
