The question does not have to be directly related to Linux and any language is fair game.

Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

For my history homework, I have to lookup the distance between like 60 cities. And, me being lazy, would like to know how to do this in C/C++. I don't know much about sockets (because I used to use dev c, on windows). Is there any cgi-script that it could use and then format the data?
Dude, you're trying to kill a fly with a sledgehammer. You don't need socket programming to look up distances between cities. By the time you've entered the names of each city in a text file, you could have the information already. Just go to www.mapquest.com, choose driving directions, then enter the city/state combinations.
To get the same result with socket programming you obviously have to set up the program, then you need to figure out the protocol (sounds like HTTP) to communicate with the server, and then parse the the data when it comes back.
If you proclaim to be "lazy" then I guarantee you writing a socket program is most definitely not the path of least resistance.
this is just a rough idea and might be a load of rubbish but anyway, when you goto one of these websites and type in the place names it must go to some html page like(this is made up)
you can see where it goes by looking at the html source and see what happens to the contents of the edit boxes. using perl or awk you could then take your file of places and produce a file containing the url's, you could then run that through wget and get the html pages with all the distances on. which you could then extract with grep.
