Dans la sortie, indiquez si chaque entier est «impair» ou «pair» dans la sortie.
Si le nombre est divisible par trois, au lieu d'indiquer que le nombre est pair ou impair, indiquez que le nombre est «divisible par trois».
Si le nombre est divisible par deux et trois, au lieu de dire que le nombre est impair, pair ou divisible par trois; déclarez que le nombre est «divisible par deux et trois».
Voici ce que je vois dans ma tentative et la sortie dans la console. Pourquoi certaines des entrées sont-elles répliquées? Je ne comprends pas ce qui ne va pas dans ma logique ici.
The number '1' is odd. The number '2' is even. The number '3' is divisible by three. ... The number '6' is divisible by two and three.

Vos calculs de quand imprimer la sortie sont indépendants, c'est-à-dire. ils s'exécutent les uns après les autres. Par conséquent, vous obtenez plusieurs lignes de sortie.
Pour implémenter les exigences "à la place", vous devez les réorganiser et les lier:
for (var i = 1; i <= 100; i++) {
if (i % 2 === 0 && i % 3 === 0) {
console.log("The number " + i + " is divisible by two and three");
} else if (i % 3 === 0) {
console.log("The number " + i + " is divisible by three");
} else if (i % 2 === 0) {
console.log("The number " + i + " is even" );
} else {
console.log("The number " + i + " is odd");
}
}
Je ne pense pas que ce soit un code valide avec else if après juste else
Bien repéré - mon erreur. J'ai corrigé ça.
Plusieurs conditions si sont satisfaites, donc vous obtenez des répétitions. Essayez de déplacer un peu le if-else: -
if (i % 2 === 0 && i % 3 === 0) {
console.log("The number " + i + " is divisible by two and three");
} else if (i % 3 === 0) {
console.log("The number " + i + " is divisible by three");
} else if (i % 2 === 0) {
console.log("The number " + i + " is even");
} else {
console.log("The number " + i + " is odd");
}
Cela arrive parce que si une valeur est divisible par 6, elle est également paire et divisible par 3. Pour y remédier, vous devez d'abord cocher 6 et vérifier 2 et 3 uniquement dans la branche else > XXX
L'ordre de vos instructions conditionnelles est important. Le code ci-dessous devrait donner le résultat que vous attendez.
for(var i = 1; i <= 100; i++) {
if(i % 2 === 0 && i % 3 === 0) {
console.log("The number " + i + " is divisible by two and three");
}
else if(i % 3 === 0) {
console.log("The number " + i + " is divisible by three");
}
else if(i % 2 === 0) {
console.log("The number " + i + " is even" );
}
else {
console.log("The number " + i + " is odd");
}
}
Regarde bien pour moi. Dites-vous qu'il ne devrait y avoir qu'un seul résultat par numéro? Par exemple, vous avez 3 entiers de 6 parce que c'est un nombre pair, il est divisible par 3 et également divisible par 2 et 3. Cela signifie que vous avez tous trois de vous si les affirmations sont remplies et de cracher donc le message de la console.log
@mwilson ouais. J'ai mis un exemple dans mon article original sur ce à quoi il est censé ressembler
Eh bien, vous vérifiez juste divisibilité par 3 avant Vous vérifiez la divisibilité des deux 2 et 3. S'il est divisible par 3, vous obtiendrez le premier message, et s'il est aussi divisible par 2 Vous obtiendrez également le deuxième message.
