Problem Statement: Virtual Restaurant

You are required to write a program for BILLING SYSTEM of a virtual restaurant. The basic idea is that by entering the meal price, your billing system will calculate the Sales Tax, Total amount and Complement offer upon that meal. The program will process the billing of undetermined number for customers. At the end, program will show sum of total amount of all the customers.

Detailed Description:

Billing System should work as under:

> You are required to take meal price as input from user.

> After getting this input, program will calculate the sales tax on it as given below:

Meal Price Sales Tax applicable

Less than or equal to 1000 No sales Tax on it.

Greater than 1000 and less than or equal to 2000 1% of meal price.

Greater than 2000 2% of meal price.

> After calculating the sales tax, program will calculate and display the total amount of the meal according to given formula:

Total Amount = Meal_Price + Sales_Tax

> Now, program will prompt to serve the complement sweet dish to customer on the basis of total amount as given below:

Total Amount Sweet Dishes

Less than 1000 Candies

Greater than or equal to 1000 and less than 2000 Sweet Bread

Greater than or equal to 2000 and less than 3000 Pudding

Greater than or equal to 3000 and less than 4000 Cake

Other amounts Trifle

> After displaying the information of one customer, the program should ask the user if he/she again wants to process the bill of another customer. The user will be given two options. If user selects "Y or y", the program will start the processing of another customer. If user selects "N or n", the billing system exits.

> Before exiting from billing system, this program should display the total number of customers it processed, and sum of total amount of all the customers.

Q#1: A Shoe manufacturing company wants to transfer its manual working system into computerized based information system. Suppose you are in the design team who is developing a technology based information system.

What factors would you consider while developing a new system? Mention at least five factors. [5 marks]

Q#2: Given diagram belongs to a certain system. Identify that the diagram belongs to closed loop system or open loop system? Give three valid reasons to support your answer. [ 2+3 marks]


Solution:



Solution Q 1.

Information Systems


In modern age, there has been felt a growing need for the use of information being in the design team I will consider the following five important factors:

· Transforming Industrial Economies

· Transformed Business Enterprise

· Emerging Digital Firms

· Emerging Global Economies

· Effective and efficient utilization of resources


Emerging Global Economies
High level of foreign trade has resulted in imports and exports which require inter linkage for smooth coordination. Core business functions (manufacturing, finance and customer support) have been distributed in different countries.


Coordination
Transforming Industrial Economies
Industrial economies have started merging as knowledge-and-information-based economies. Manufacturing activities being shifted to low wage countries. More opportunities are available in education, health care, banks, insurance firms and law firms. More knowledge and information intense products are being created. Higher commitment expected from customer e.g. overnight package delivery, worldwide reservation systems.


Transformed Business Enterprise
The structure of business enterprise have also changed, initially the organizations used to be Hierarchical, Centralized, Structured following a Fixed Set of SOP’s. However, now the organizations are moving towards more Flatter, Decentralized and Flexible structures. Information Technology makes it convenient and efficient to promote this new culture.


Emerging Digital Firms
Firms where all significant business process and relationships with customers and suppliers and employees are digitally enabled and key corporate assets are managed through digital firms. This results in rapid response with more flexibility to survive and getting more global.


Effective and efficient utilization of resources
Effectiveness and efficient usage of resources has become a dire need of today’s organization and it cannot be ignored


Solution Q 2.
This system is a closed system because

· Input is manipulated in a controlled mechanism

· It is not connected with the environment

· Neither environment exerts any influence on the system nor does system influence the environment

Assignment Question:

Question# 1 (5)

a) In minting stage of E-cash payment system, what mechanism is used to make the serial number (generated by client’s cyber wallet) blind? (2)

b) Assume that you want to buy a low cost item like shoes, wallet etc, what payment system do you suggest for this transaction and why? (3)

Question# 2 (5)

Suppose you want to buy an apple iphone from an online shopping site through E-cash payment system. What steps would be followed to make this transaction?

Solution:

solution Question 1
a) At this stage the bank knows as to who amongst its different account holders or clients is requesting for the bank’s signatures on the serial no., but it does not know the serial no. it is signing due to the blinding factor “r”.

b) Here in Pakistan, people are not use to of plastic money, specially the small vendors. if i am buying a low cost product than i will pay through cash to avoid long procedure of bank.

This purchase will take the following steps.........

E-Cash & the Web

Merchant Software
Merchant Client Software
Wallet Client
Wallet Web
Browser
Web Server
wallet Starts
1.Select Order
2. Merchant
3. Payment Request (Order)

13, 3,1,2,4,12,10,5,8,7,6,9,11,14,15,18

After making a BST perform the following operations on it.

a) Pre order Traversal

b) Inorder Traversal

c) Postorder Traversal

Solution:

a) Pre Order Traversal

Answers

Question No.1 (Marks = 10)

a) How many combinations of bits are exist when we make a truth table of 9 inputs?

2ⁿ are the total combinations of bits in Truth table, where n is number of variables, so

2⁹=512

512 bits will there

b) Prepare a truth table for the following I = (w + x) Å (y . z) where w, x, y and z are four binary inputs in the truth table.

Note :(Å symbol represent XOR gate)

Solution:

Remember in XOR, output will high only if only all inputs are mismatch to each others.

Inputs						Output
W	X	Y	Z	w+x	y.z	(w + x) Å (y . z)
