libcurl is a popular library for fetching web pages.

Alternatively, just use the wget programme as part of a script to fetch the data, and then your C++ programme to operate on it.

but how ?

That is much, much harder. Find a webpage where the values are plain text in the html source.

Steps to get data from a website
First, find the page where your data is located. ...
Copy and paste the URL from that page into Import.io, to create an extractor that will attempt to get the right data. ...
Click Go and Import.io will query the page and use machine learning to try to determine what data you want.
