Answer:

The correct answer to the following question is option "b".  

Explanation:

The method having the same name but the arguments have different so it is called method overloading. It is a part of the object-oriented programming language (oops).  

  • In the given code we define same method two times that is "mystery()". but in this method, we pass two different parameters. For the first time, we pass a double variable that is "a" as a parameter. In the second time, we pass an integer variable that is "a" as a parameter and in both functions, we write some codes.
  • In the calling time, we call function two times. In first time calling we pass an integer value that is "1" and second time calling we pass double value that is "1.0". So the output of this code is "int! double!".  

That's why the option "b" is correct.

Design a program that asks the user to enter a store’s sales for each day of the week. The amounts should be stored in an array.
sdas [7]

Answer:

Program given below

Explanation:

Total Sales

Assign the values of the variable as “Enter the store sales for Sunday” in Sun

Assign the values of the variable as “Enter the store sales for Monday” in Mon

Assign the values of the variable as “Enter the store sales for Tuesday” in Tue

Assign the values of the variable as “Enter the store sales for Wednesday” in Wed

Assign the values of the variable as “Enter the store sales for Thursday” in Thu

Assign the values of the variable as “Enter the store sales for Friday” in Fri

Assign the values of the variable as “Enter the store sales for Saturday” in Sat

Assign the values for the variable in array as [Sun, Mon, Tue, Wed, Thu, Fri, Sat]

Initialize tot = 0

Use the loop for calculating the total sales for the week,

for total_sales in store_sales:

    tot += total_sales

then display the result as,    

print "\n Total week sales = %2.f " %tot

sun = int(input("\n Enter the store sales for Sunday: "))

mon = int(input("\n Enter the store sales for Monday: "))

tue = int(input("\n Enter the store sales for Tuesday: "))

wed = int(input("\n Enter the store sales for Wednesday: "))

thu = int(input("\n Enter the store sales for Thursday: "))

fri = int(input("\n Enter the store sales for Friday: "))

sat = int(input("\n Enter the store sales for Saturday: "))

store_sales = [sun, mon, tue, wed, thu, fri, sat]

tot = 0

for store_sale in store_sales:

tot += store_sale

print "\n Total Week Sales: %2.f" %tot

We will have the following output:

<u>OUTPUT </u>

<u> </u>Enter the store sales for Sunday: 45

Enter the store sales for Monday: 56

Enter the store sales for Tuesday: 89

Enter the store sales for Wednesday:78

Enter the store sales for Thursday: 45

Enter the store sales for Friday: 12

Enter the store sales for Saturday: 23
