我正在写一个热门应用或冷应用。我需要一个switch语句来决定用户是热还是冷。到目前为止,这是我的代码:
switch(true) {
case (userGuess / secretNumber === 1):
setFeedback("You win");
finish = true;
break;
case ((userGuess - secretNumber) > 50):
setFeedback("You're ice cold!");
break;
case ((userGuess - secretNumber) > 30):
setFeedback("You're cold!");
break;
case ((userGuess - secretNumber) > 20):
setFeedback("You're warm!");
break;
case ((userGuess - secretNumber) > 10):
setFeedback("You're hot!");
break;
case ((userGuess - secretNumber) > 0):
setFeedback("You're blazing hot!");
break;
}

编辑: 我试图用开关替换以下if / else语句。请告诉我它是否可能,如果可能,如何:这是旧代码:
if (userGuess / secretNumber === 1){
setFeedback("You win");
finish = true;
} else if ((secretNumber - userGuess) > 60.5){
setFeedback("Wow! You are freezing!");
} else if ((secretNumber - userGuess) > 55.5){
setFeedback("Wow! You better put on a jacket cause its super cold!");
} else if ((secretNumber - userGuess) > 50.5){
setFeedback("Its is super cold man!");
} else if ((secretNumber - userGuess) > 40.5) {
setFeedback("Now you are cold!");
} else if ((secretNumber - userGuess) > 30.5) {
setFeedback("It's getting warm around here");
} else if((secretNumber - userGuess) > 20.5) {
setFeedback("It's getting very warm in here!");
} else if((secretNumber - userGuess) > 15.5) {
setFeedback("It's getting very very warm in here!");
} else if ((secretNumber - userGuess) > 7.5){
setFeedback("It's hot!");
} else if ((secretNumber - userGuess) > 5.5){
setFeedback("It is very hot here!");
} else if ((secretNumber - userGuess) > 1.5){
setFeedback("I am burning here!!");
} else if ((secretNumber - userGuess) > 0.5){
setFeedback("Its is hotter than the sun!!!!!");
} else {
}

答案 0 :(得分:0)
int value = secretNumber-userGuess;
if ((userGuess / secretNumber) == 1)
{
setFeedback("You win");
finish = true;
}
else if (value > 60.5)
setFeedback("Wow! You are freezing!");
else if (value > 55.5)
setFeedback("Wow! You better put on a jacket cause its super cold!");
else if (value > 50.5)
setFeedback("Its is super cold man!");
else if (value > 40.5)
setFeedback("Now you are cold!");
else if (value > 30.5)
setFeedback("It's getting warm around here");
else if (value > 20.5)
setFeedback("It's getting very warm in here!");
else if(value > 15.5)
setFeedback("It's getting very very warm in here!");
else if (value > 7.5)
setFeedback("It's hot!");
else if (value > 5.5)
setFeedback("It is very hot here!");
else if (value > 1.5)
setFeedback("I am burning here!!");
else if (value > 0.5)
setFeedback("Its is hotter than the sun!!!!!");
else {
}
