CS304-OOP Assignment 3 #Learning Outcomes

Students will be able to:

o Define base and derived classes with their respective data members and member functions

o Implement Multiple Inheritance.

CS304-OOP Assignment 3 #Problem Statement

Consider yourself working as a software engineer in a marketing company of both hardware and software. The IT manager has given you a task to model a part of their simple advertising system. In this system, there will be four classes named Item, Sales, hwItem (Hardware Item), swItem (Software Item)

Steps to follow:

1. Create a base class Item that should store the title of the item (a string) and its price (a float).
2. Then create another base class called Sales which should contain an array of three floats so that it can record the sale in rupees of a particular item for the last three months.
3. After that derive two classes hwItem (hardware item) and swItem (software item) from both Item and Sales classes. The hwItem class should hold category of the item and its original manufacturer (om), whereas the swItem class should contain the type of the software and the Operating System (os) under which it works.
4. Each class should have its own getData() and displayData() functions to input and output data respectively.

The following hierarchy of classes should be used for the assignment solution.

ENG101-English Comprehension Assignment #Questions

Q1. Thinking, speaking and writing are closely related to each other. If you are familiar with the essential rules of good English and think clearly, you will speak and write with confidence - the confidence that comes from a sense of having mastered the rules and conventions which must be followed in all acceptable writing. Keeping this in mind, define a sentence and write down 5Ws (who, what, where, when why) for each of the sentences in the given table. (3+1*7=10 Marks)

Q2. Writing is not easy, especially in a foreign language. Writing is, in fact, a process. It is done in a series of steps and stages. A paragraph is a series of sentences about one main thought, idea or point. A paragraph typically starts with a point and the rest of the paragraph provides details to support and develop that point. Keeping this in mind, arrange the following paragraph in the suggested order. Also, provide a suitable title to the given text.

1. Her parents are going to stop giving her money after college. 2 She is in search of a job. 3. She decided to get information about applying to the job. 4. Anna is a senior student in college. 5. This morning, she read in the paper about a job downtown. 6. Life there can be very difficult.7. It is expensive. 8. She lives in New York City. 9. The job sounded interesting and offered good pay.

CS601-Data Communication Assignment #Questions

Question. 1                             (5 Marks)

Suppose a station (PC-1) wants to transmit a message to a station (PC-2) as a list of five 4-bit numbers. In order to have an error-free transmission, PC-1 adds a 4-bit checksum at the end of this message to enable error detection at the receiver end. If the set of data contained in the message is (5, 12, 15, 3, 10), calculate the 4-bit checksum needed to be appended with the data using the one’s compliment arithmetic.

Question. 2                            (5 Marks)

A station is transmitting data at a rate of 1.5Mbps over a channel which gets affected by an instantaneous noise source for a short period of time. If the noise occurs for duration of 0.1 msec (milliseconds), how many bits are going to be impacted by this burst error?


Question #3:                         (5 Marks) 

In Block-coding, we divide our message into blocks, each of ‘k’ bits, called datawords and then add ‘r’ redundant bits to each block to make the length ‘n = k + r’. The resulting ‘n-bit’ blocks are called codewords. Two station agree upon using an “odd parity” block coding scheme in which every datawords is appended with one parity bit to make an odd parity codeword (Number of 1s in the codeword should be odd). If they use dataword of length 3 (k=3), then draw the table for this coding scheme representing each dataword with its corresponding codewords.
