99 Bottles of Beer
From Rosetta Code
99 Bottles of Beer a programming puzzle. It lays out a problem which Rosetta Code users are encouraged to solve, using languages and techniques they know. Multiple approaches are not discouraged, so long as the puzzle guidelines are followed. For other Puzzles, see Category:Puzzles.
In this puzzle, write code to print out the entire "99 bottles of beer on the wall" song. For those who do not know the song, the lyrics follow this form:
X bottles of beer on the wall X bottles of beer Take one down, pass it around X-1 bottles of beer on the wall X-1 bottles of beer on the wall ... Take one down, pass it around 0 bottles of beer on the wall
Where X and X-1 are replaced by numbers of course. Grammatical support for "1 bottle of beer" is optional. As with any puzzle, try to do it in as creative/concise/comical a way as possible (simple, obvious solutions allowed, too).

[edit] The simple solution
#include <stdio.h>
int main() {
int bottles = 99;
do {
printf("%d bottles of beer on the wall\n", bottles);
printf("%d bottles of beer\n", bottles);
printf("Take one down, pass it around\n");
printf("%d bottles of beer on the wall\n\n", --bottles);
} while( bottles > 0 );
return 0;
}
[edit] A preprocessor solution
Of course, with the template metaprogramming solution, the program has still do the conversion of numbers to strings at runtime, and those function calls also cost unnecessary time. Couldn't we just compose the complete text at compile time, and just output it at run time? Well, with the preprocessor, that's indeed possible:
#include <stdio.h>
#define BOTTLE(nstr) nstr " bottles of beer"
#define WALL(nstr) BOTTLE(nstr) " on the wall"
#define PART1(nstr) WALL(nstr) "\n" BOTTLE(nstr) \
"\nTake one down, pass it around\n"
#define PART2(nstr) WALL(nstr) "\n\n"
#define MIDDLE(nstr) PART2(nstr) PART1(nstr)
#define SONG PART1("100") CD2 PART2("0")
#define CD2 CD3("9") CD3("8") CD3("7") CD3("6") CD3("5") \
CD3("4") CD3("3") CD3("2") CD3("1") CD4("")
#define CD3(pre) CD4(pre) MIDDLE(pre "0")
#define CD4(pre) MIDDLE(pre "9") MIDDLE(pre "8") MIDDLE(pre "7") \
MIDDLE(pre "6") MIDDLE(pre "5") MIDDLE(pre "4") MIDDLE(pre "3") \
MIDDLE(pre "2") MIDDLE(pre "1")
int main()
{
printf(SONG);
return 0;
}
An inspection of the generated executable proves that it indeed contains the complete text of the song in one block.

[edit] The simple solution
#include <iostream>
using namespace std;
int main() {
int bottles = 99;
do {
cout << bottles << " bottles of beer on the wall" << endl;

cout << "Take one down, pass it around" << endl;

} while (bottles > 0);

[edit] A template metaprogramming solution
Of course, the output of the program always looks the same. One may therefore question why the program has to do all that tedious subtracting during runtime. Couldn't the compiler just generate the code to output the text, with ready-calculated constants? Indeed, it can, and the technique is called template metaprogramming. The following short code gives the text without containing a single variable, let alone a loop:
#include <iostream>
template<int max, int min> struct bottle_countdown
{
static const int middle = (min + max)/2;
static void print()
{
bottle_countdown<max, middle+1>::print();
bottle_countdown<middle, min>::print();
}
};
template<int value> struct bottle_countdown<value, value>
{
static void print()
{
std::cout << value << " bottles of beer on the wall\n"
<< value << " bottles of beer\n"
<< "Take one down, pass it around\n"
<< value-1 << " bottles of beer\n\n";
}
};
int main()
{
bottle_countdown<100, 1>::print();
return 0;
}
[edit] A Recursive solution
#include <iostream>
using namespace std;
void rec(int bottles)
{
if ( bottles!=0)
{
cout << bottles << " bottles of beer on the wall" << endl;
cout << bottles << " bottles of beer" << endl;
cout << "Take one down, pass it around" << endl;
cout << --bottles << " bottles of beer on the wall\n" << endl;
rec(bottles);
}
}
int main()
{
rec(99);
system("pause");
return 0;
}

Since MAXscript is an expression based language (everything returns a value), it is relatively easy to write long expressions that are only one line long. the following single-line snippet (broken for clarity on the webpage) produces a grammatically correct printout of the song.
for i = 99 to 1 by -1 do (print (i as string + (if i == 1 then " bottle" else " bottles") + " of beer on the wall\n" + i as string +\
(if i == 1 then " bottle" else " bottles") + " of beer\nTake one down, pass it around\n" + (i - 1) as string + (if i - 1 == 1 then "\

A straightforward approach:
Smalltalk at: #sr put: 0 ; at: #s put: 0 !
sr := Dictionary new.
sr at: 0 put: ' bottle' ;
at: 1 put: ' bottles' ;
at: 2 put: ' of beer' ;
at: 3 put: ' on the wall' ;
at: 4 put: 'Take one down, pass it around' !
99 to: 0 by: -1 do: [:v | v print.
( v == 1 ) ifTrue: [ s := 0. ]
ifFalse: [ s := 1. ].
Transcript show: (sr at:s) ; show: (sr at:2) ; show: (sr at:3) ; cr.
v print.
Transcript show: (sr at:s) ; show: (sr at:2) ; cr.
(v ~~ 0) ifTrue: [ Transcript show: (sr at:4) ; cr. ].
