*****高中时代*****

10 PRINT "HELLO WORLD"
20 END

*****大学新生*****

program Hello(input, output)
begin
writeln('Hello World')
end.

*****高年级学生*****
(defun hello
(print
(cons 'Hello (list 'World))))

*****新来的程序员*****
#include
void main(void)
{
char *message[] = {"Hello ", "World"};
int i;
for(i = 0; i = 0) {
while(defined($arg=shift(@ARGV))) {
$outfilename = $arg;
open(FILE, ">" . $outfilename) || die "Can't write $arg: $!\n";
print (FILE $msg);
close(FILE) || die "Can't close $arg: $!\n";
}
}
else
{
print ($msg);
}
1;

*****中级HACKER*****
#include
#define S "Hello, World\n"

main()
{exit(printf(S) == strlen(S) ? 0 : 1);}

*****老练的HACKER*****
