Assignment

An expression is given here. You are required to write a C++ program that solves the given mathematical expression.

Z = x2 + 2xy – x/y
set the values of x = 2 and y = 1

Three main tasks are to be done by each student:-

Expression solving Decisions making (if-else structure) Repetition structure (while loop).

After evaluation of above expression, you should add the value of z to last digit of your vu id. As a result,

If you get an odd number, then you should print your VU id using while loop. This while loop should run as many times as odd number you got from (z+ last digit of your vu id).
For example, suppose the value of z is 2 and the student’s id is BC123456781. Then by adding last digit of vu id 1 to value of z, result will be 3 which is an odd number. In this case, program should print your VU ID for 3 times using while loop.

Sample screen shot::

If you get an even number, then you should print your Name using while loop. This while loop should run as many times as even number you got from (z+ last digit of your vu id).
For example, suppose the value of z is 2 and the student’s id is BC123456782. Then by adding last digit of vu id 2 to the value of z, result will be 4 which is an even number. In this case, program should print your Name for 4 times using while loop.

Sample screen shot::

NOTE: Values of “z” and “student’s id” are arbitrary (not real).

@black-angel said in CS101 Topic-003. Search engines Discussion:

what is difference in between (.com) and (.org).

Dear Student,

(.com) and (.org) are called TLDs ( Top Level Domains ), these name extensions are used at the end of website URLs in order to help categorize them. (.Org) is primarily used by non-profit organizations, while (.com) is used mostly by for-profit businesses.

@devesh-chiquitosen said in CS101 Lecture 1 Discussion:

sir what is bing?

Dear Student,

Microsoft Bing is a web search engine like Google,it is owned and operated by Microsoft. Bing search engine provides a variety of search services, including web, video, image and map search products and etc.

Regards

@ghulam-farid said in What is paper pattern?:

please sir define the paper pattern of vu

The pattern of exams (Midterm & Final) is the same as previous semesters (Objective & Subjective). Moreover, almost 50 % will consist of multiple-choice questions and almost 50 % will consist of 3 marks and 5 marks questions. However, if there will be any change in the exams pattern due to the COVID-19 pandemic, it will be announced so keep visiting the announcement section on VULMS and VU Student Email regularly for the latest updates.

@engr-ali said in decimal fractions:

Assallamulikum Sir, Conversion (59)10 into binary 59/2=28-1 ? 28/2=14-0 14/2=7-0 7/2=3-1 3/2=1-1 (111001) ?

Dear @Engr-Ali ,

$(59){10} = (111011){2}$

The mistake you have made is in the first step where you divided $59/2$. It has to be $29-1$ instead of $28-1$.

Best wishes

@vu-kick said in Errors in Computations.:

What is synchronous and asynchronous and what are there applications in real world. Which applications use this sort of techniques.

The word synchronous and asynchronous are very general terms that are used in different fiels representing different phenonena. If you can please ask it more clearly that in what context you are asking. It will be good if you please mention what page of handouts, what slide of ppts or where in the lecture video of the numerical analysis you studied/heard about it. Then we’ll be able to explain it well.

Best wishes
