Question

Something is wrong with the logic in the program above. For which values of time will the greeting "Good Morning!" be displayed? var time = promptNum("What hour is it (on a 24 hour clock)?"); var greeting = ""; if (time < 6) { greeting = "It is too early!"; } else if (time < 20) { greeting = "Good Day!"; } else if (time < 10) { greeting = "Good Morning!"; } else { greeting = "Good Evening!"; } console.log(greeting);

Answer 1

There is logic problem in condition of elseif statement that is (time<20).

Step-by-step explanation:

elseif(time<20) will be true for time<10 that means program will never greet good morning as to make logic correct either change condition from elseif(time<20) to elseif(time<20&& time>=10). Or change the order of condition like check first for elseif(time<10)

solution 1

if (time < 6) { greeting = "It is too early!"; }

else if (time < 20 && time>=10) { greeting = "Good Day!"; }

else if (time < 10) { greeting = "Good Morning!"; }

else { greeting = "Good Evening!"; }

console.log(greeting);

solution 2

if (time < 6) { greeting = "It is too early!"; }

else if (time < 10) { greeting = "Good Morning!"; }

else if (time < 20 ) { greeting = "Good Day!"; }

else { greeting = "Good Evening!"; }

console.log(greeting);
