C++ Programming: How to dowload a file from a URL on the internet?

Question

For example:

Say there was a file: www.testpage.com/file.txt
And I wanted to download "file.txt" to my computer.

What classe(s) and lines of code do I use?

Or better yet, do you know of an online tutorial that can explain this to me in detail?

Thanks

Answer 1

I don't think this answer is quite what you want, but it might be helpful any way.

If you are using osX Linux or Unix you can use curl.

i.e., curl www.testpage.com/file.txt > filename
