Utilisation d'instructions conditionnelles

Opérateurs > Opérateurs de programmation > Utilisation d'instructions conditionnelles

Vous pouvez utiliser les opérateurs conditionnels pour définir des fonctions.

évaluez l'instruction conditionnelle à un point comme suit :

elseif	alsoif

elseif

alsoif

Lorsque vous utilisez elseif, le programme arrête d'évaluer les instructions quand il atteint la première instruction vraie. Lorsque vous utilisez alsoif, le programme évalue toutes les instructions alsoif. Si l'une d'elles est vraie, le programme n'évalue aucune des instructions else suivantes.
