Challenge
Recreate "99 Bottles of Beer on the Wall", using the least bytes possible.
Lyrics:
99 bottles of beer on the wall, 99 bottles of beer.
Take one down and pass it around, 98 bottles of beer on the wall.
98 bottles of beer on the wall, 98 bottles of beer.
Take one down and pass it around, 97 bottles of beer on the wall.
97 bottles of beer on the wall, 97 bottles of beer.
Take one down and pass it around, 96 bottles of beer on the wall.
96 bottles of beer on the wall, 96 bottles of beer.
Take one down and pass it around, 95 bottles of beer on the wall.
95 bottles of beer on the wall, 95 bottles of beer.
Take one down and pass it around, 94 bottles of beer on the wall.
....
3 bottles of beer on the wall, 3 bottles of beer.
Take one down and pass it around, 2 bottles of beer on the wall.
2 bottles of beer on the wall, 2 bottles of beer.
Take one down and pass it around, 1 bottle of beer on the wall.
1 bottle of beer on the wall, 1 bottle of beer.
Go to the store and buy some more, 99 bottles of beer on the wall.
Rules
- 0-byte answers aren't allowed. Although 1-byte answers are allowed while still abiding to not using loopholes, they won't be very interesting (unless you DO make it interesting).
- Use any form of output in the program. Yes, the whole thing must be outputted up until you reach $n=1$.
- Built-in functions and/or code for this specific challenge is pretty much allowed, only if you explain (even a little) how the code works (or not if you can't at all).
- Shortest program of each language used is the winner.

Main golfing techniques:
-
The repetitive part has been put into a function
-
conditional strings are sometimes implemented using pointer arithmetic, using the fact that C strings are zero terminated character arrays
-
The code uses the implicit int rule
-
I'm passing a pointer through an int argument which then in turn is interpreted as a pointer by
printf(not portable and definitely not clean; allows me to use the implicit int rule for that argument) -
The gcc extension
condition?:value(giveconditionunless that is zero, in which case givevalue) is used to save one character -
The printf function is declared implicitly (which isn't guaranteed to work by any C standard, but works just fine in practice by any compiler that allows implicit declarations), saving the 18 characters that would otherwise be needed for
#include<stdio.h>(including the mandatory line break following that directive)

This shortened if-else condition thingy is actually pretty good.
