Question

Write a program that asks a user to enter a date in month day year format (for example 10 12 2016) and displays the day of the week for that date, in this case, Wednesday.

Answer 1

Answer and Explanation:

Using javascript:

function dayof_theweek(){

var TodayDate = window. prompt("enter today's date in the format 'year, month, day' ");

var Datenow=new date(TodayDate);

var Dayofweek=Datenow.getday();

var Days=["monday","Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"];

if(Dayofweek==indexOf(Days[Dayofweek]))

{

document.createTextnode(Days[Dayofweek]);

}

}

The program above uses a date object which uses the method getday to get the day of the week(get day returns an integer from 0 to 6).we then use a comparison operator == to test the condition that returned value Dayoftheweek is same with the index of the array Days and then print to a html document. The program may need improvements such as the fact that errors may arise when proper input isn't given, and therefore must be handled.
