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.
Answer:
def replace_at_index(str, number):
new = str.replace(str[number], "-")
return new
print(replace_at_index("eggplant", 3))
Explanation:
- Create a function called <em>replace_at_index</em> that takes a string and an integer
- Initialize a new variable called <em>new</em>, that will hold the new string
- Replace the character at given index with dash using <em>replace</em> function, it takes two parameters: the first is the character we want to replace, the second is the new character.

Answer:
#program in python.
#variables
slice_area=14.125
pi=3.14159
#read diameter
d=int(input("Enter diameter of pizza:"))
#area of pizza
area=pi*(d/2)*(d/2)
#number of slice
no_slice=int(area/slice_area)
#print slice
print("total silce are:",no_slice)
Explanation:
Declare and initialize a variable "slice_area" with 14.125 which is the area of a pizza slice.Initialize a variable "pi" with 3.14159.Then read the diameter of pizza.Find the area of pizza as "area=pi *d/2*d/2".Divide the total area with area of pizza slice.This will be the number of slice.
Output:
Enter diameter of pizza:20
total silce are: 22
Answer:
true
