I'm working on a new version of QTSender (look over here)

Here's my question:
How do I output a random line from a text file with a command.

code:

---

This is the content of hello.txt in the folder C:\...\plugins\QTSender\.

\x03#0000FFHello there!
\x03#0000FFHey you!
\x03#0000FFHello! How are you?
\x03#0000FFHey my friend!
\x03#0000FFHello buddy!

---

I know the formatting will work the only thing I'm wondering about is how to load it.
EXAMPLE:
You type /xQThello

and it outputs:
Hello buddy!

I'm working in C.
