Scenario: ABC Supermarket is a local township supermarket based in Germiston, East rand of Johannesburg in

South Africa. The supermarket sells a wide variety of food and household products.

The supermarket takes online orders through their website and currently averages about 20 000

unique visitors to their website per day and has 10 content uploaders constantly updating their

website and making sure the site is always up-to-date. The website is in highest demand from 07:00

until 17:00 Mondays to Saturdays and very minimal activities on any other times. The website is hosted and managed locally by a small IT department of six employees. Besides not

coping with the website traffic load, the local energy supplier, Eskom has decided to implement load

shedding at different times of the day

Question A. Self-healing and redundancy(Marks: 30)

Explain any five recommendations that should be looked at related to the principles of selfhealing and redundancy in the design of the ABC supermarket module

Assign numMatches with the number of elements in userValues that equal matchValue. userValues has NUM_VALS elements. Ex: If userValues is {2, 1, 2, 2} and matchValue is 2 , then numMatches should be 3.

Your code will be tested with the following values:

matchValue: 2, userValues: {2, 1, 2, 2} (as in the example program above)

matchValue: 0, userValues: {0, 0, 0, 0}

matchValue: 10, userValues: {20, 50, 70, 100}

Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print:

7 9 11 10 
10 11 9 7 

Write three statements to print the first three elements of array runTimes. Follow each statement with a newline. Ex: If runTime = {800, 775, 790, 805, 808}, print:

800 
775 
790

A library charges a fine for every book returned late. For first 5 days the fine is 50 Rs, for 6-10 days fine is 100 rupee and above 10 days fine is 150 rupees. If you return the book after 30 days your membership will be cancelled. Write a program C# to accept the number of days the member is late to return the book and display the fine or the appropriate message.

IPL Match Details

Write a program that reads all the match outcomes and summarizes the information of all the matches.

Points are given to the terms based on the outcome of the match.

A win earns a team 3 points.A draw earns 1.A loss earns 0.

The following information is expected:

MP:Matches Played

W:Matches Won

D:Matches Drawn(Tied)

L:Matches Lost

P:Points

The team information should be displayed in descending order of points.

Sample input 1

6

CSK;RR;loss

RR;DD;draw

MI;KKR;win

KKR;RR;loss

CSK;DD;draw

MI;DD; draw

Sample output 1

Team: RR, Matches Played: 3, Won: 2, Lost: 0, Draw: 1, Points: 7

Team: MI, Matches Played: 2, Won: 1, Lost: 0, Draw: 1, Points: 4

Team: DD, Matches Played: 3, Won: 0, Lost: 0, Draw: 3, Points: 3

Team: CSK, Matches Played: 2, Won: 0, Lost: 1, Draw: 1, Points: 1

Team: KKR, Matches Played: 2, Won: 0, Lost: 2, Draw: 0, Points: 0

Build a GPA calculator that inputs grades of 3 different subjects along with the credit hours

from the user and displays the user’s GPA. The input grades and their corresponding grading

points are given below.

Grade Points

A 4.0

A- 3.67

B+ 3.33

B 3.0

B- 2.67

C+ 2.33

C 2.0

C- 1.67

D+ 1.33

D 1.0

F 0

The formula is

GPA = (GP1 * CH1 + GP2 * CH2 + GP3 * CH3)/ (CH1 + CH2 + CH3)

Where GP1 is Points of Subject 1 and CH1 show credit hours of subject 1.
