I need help with reading data from web page. I wanted to do database of rates (forex). For example: whan price is (eur\usd) 1.4231 then 1.4230 then 1.4229 then 1.4230. I wnated to make text file and application (c\c++) write there those price.
In tex file:
1.4231
1.4230
1.4229
1.4230
every movement are in this file.
It is possible ??? I know how can I make text file and write on it. But I need get data from web page.

It's probably 10x easier in C# but it can be done.

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.

commented: yep +15

It's probably 10x easier in C# but it can be done.

but how ?

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