my guitar string has broke.?

Hey don't sweat it! Strings are disposable; I break them all the time. It can be kind of startling though, especially if you're in the middle of a song. With beginners it's common to break a string while tuning. You probably tried to tune the string too high, so it snapped. Single strings cost around a dollar to replace, so no biggie. If your guitar has been sitting around since you were six, then you could probably do with a whole new set (strings should be changed every so often even if they don't break). You can get a decent set for around $7.50. Get lights rather than heavy or medium. I usually recommend D'Addario EJ16 Light Acoustic Strings.

Now about tuning. I would recommend you get a digital tuner to help you. An easy one to use is the Korg GA-1 Guitar Tuner. It's a little pricier than the strings, around $15, but well worth it, because you won't break so many strings and you'll know your guitar is in tune (an out of tune guitar sounds awful no matter who is playing it). You should be able to find both the strings and the tuner at your local music store (check out the sources below for pictures of what to look for).

Now at this point your guitar may be totally out of wack, and may have strings already tuned too high. So to avoid breaking any more, I would loosen all the strings so they're a little slack. You shouldn't do this every time, just for this first time. Now, the first thing to know is the notes of the strings: EADGBE, or Eddie Ate Dynamite Good Bye Eddie ;). Turn your tuner on and pluck the lowest string on your guitar (that's the top sting). As you pluck the string, turn the corresponding tuner counter-clockwise until you your tuner says "E," and the light is green. The line on the screen should be pointing straight up. If the line is tilted a little to the left, that means the note is a little flat, or too low in pitch, so you should tighten it a little more. If the line is tilted a to the right then the note is sharp, or too high in pitch, and so you should loosen it. Do the same with the next string, only of course you'll want to tune it to "A." If it seems like the pitch of the string isn't changing as you turn the knob-- STOP! You're probably tuning the wrong string (happens to me sometimes). Once your guitar is in tune, you should tune it every time you play it, and unless your little sister or brother has been playing with the knobs, you shouldn't have to turn the knobs very far at all.

You can also tune a guitar without a tuner, but it's tough since your ear isn't trained yet. This youtube gives a pretty good tutorial: http://www.youtube.com/watch?v=kDqmAqAZq0c

So don't give up! Good luck!

You can take it to a music store and talk to the person running the place. They'll know how to get you a new string and it will probably only be a few dollars, 10 tops. It might be more if you want them to do all the strings, which may be a good idea as it sounds like your strings are pretty flimsy.

Good luck with your playing, sweetie!

take it to music store and have it restrung for 5 bucks
