Le but de la manipulation est d'ecrire un programme qui affichera "HELLO WORLD" a l'ecran.
Voici la reponse de quelques personnes a ce petit test (celle du PDG est très prisée ...)
Terminale
10 PRINT "HELLO WORLD"
20 END
DUT 1ère année
program HELLO(input, output)
begin
writeln('HELLO WORLD')
end.
DUT 2ème année
(defun HELLO
(print
(cons 'HELLO (list 'WORLD))
)
)
Fraîchement sorti de l'école d'ingénieur
#include <
void main(void) {
char *message[] = {"HELLO ", "WORLD"};
int i;
for (i=0 ; i<<2 ; ++i)
printf("%s", message[i]);
printf("\n");
}
