Old lady swallowed a fly

Present a program which emits the lyrics to the song I Knew an Old Lady Who Swallowed a Fly, taking advantage of the repetitive structure of the song's lyrics.

Old lady swallowed a fly is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

C

Boring, ad hoc dictionary based decompression. The encoder was arguably more interesting, though. <lang c>#include <stdio.h>

char *dict[] = { "_ha _c _e _p,/Quite absurd_f_p;_`cat,/Fancy that_fcat;_j`dog,/What a hog" "_fdog;_l`pig,/Her mouth_qso big_fpig;_d_r,/She just opened her throat_f_" "r;_icow,/_mhow she_ga cow;_k_o,/It_qrather wonky_f_o;_a_o_bcow,_khorse.."

int print(char *c, int s) { do { if (s) s = print(dict[*c - 95], 0); else if (*c == '_') s = 1; else putchar(*c == '/' ? '\n' : *c); } while (*++c); return s; }

int main() { print(dict[0], 0); return 0; }</lang>
