In the C programming language, how do I download an HTTP file using the url to the file?
Link to a simple example program would be nice, I did search, but I cant find it.

Do I use the same method for HTTPS pages?

Take a look at libcurl :

There's alot of documentation and examples on how to use it.
It supports HTTP, HTTPS and much more.

you can use external programs like wget:
char * command[1024];
sprintf(command,"wget \"%s\"",myurl);

If you are on Windows, a simple

#include <urlmon.h>


will do (also for HTTPS).

I'd recommend against launching external programs using 'system()' simply for the console window that will pop up.

Almost forgot,
I am going to be downloading from certain websites to record historical data from them and make my own personal version that has all the data they have put on the internet, (Newegg historical prices for one).

I don't think that makes a difference...
