( #3333=superdoc: print w/ replies, xml ) Need Help??
I hope this is the right place for this. I have been messing with perl a bunch today a managed to take advantage of how Perl and C use different comment characters. Here are two methods to write a program that runs as either C or Perl:
#include <stdio.h> // prints 99 Bottles of beer on the wall. Works as +either a C or a Perl program. #define PERL C /* "*/ int main(){//"; { int $bottles; $bottles=99; while($bottles){ printf("%d bottle%s of beer on the wall, %d bottle%s of beer.\ +n", $bottles, $bottles==1?"":"s", $bottles, $bottles==1?"":"s"); printf("Take one down and pass it around, "); if($bottles==1){ printf("no more bottles of beer on the wall.\n\n"); } else{ printf("%d bottle%s of beer on the wall.\n\n", $bottles-1, + $bottles==2?"":"s"); } $bottles--; } printf("No more bottles of beer on the wall, no more bottles of be +er.\n"); printf("Go to the store and buy some more, 99 bottles of beer of t +he wall."); }
and using a bit different method:
#include <stdio.h> #define sub void #define $x char *$t #define chomp gets sub main(){ $x; printf("Please enter your name: "); #if 0 $t = <>; #endif chomp($t); printf("Hello, %s!", $t); } #if 0 main(); #endif
