In traditional universities, students face their teachers in a live environment due to which their communication skills are more refined as compared to students in a distance learning environment. In the context of virtual university, that strives to fill this gap by introducing live adobe classes and face to face sessions in campuses. To what extent do you agree that these activities are helpful for improving communication skills of students? Also, give suggestions for further improvements.

Q):No doubt that Speaking skills are key factor of communication, but listening skills are equally important. Elaborate the statement in best of your understanding.

We all may be well aware of height checking machine currently used in our society. This machine is manually operated by humans and its readings are not quit precise. A well reputed medical institute took initiative to automate this task to get accurate results. They automated this task by using photo sensors to take readings. Photo sensor takes readings and convert them to display on the 7 segment display. In your opinion which encoding mechanism will be used by the institute for automating this task?

You have to give valid arguments by keeping in view the following points:

Accuracy

Display time

Given is an infix expression:

A + B * C / (D-B)

Write a complete program in C++ to convert the above infix expression into postfix notation

In the binary number system, we represent numeric values using two different symbols which is typically 0 and 1. Suppose we have a tertiary number system, which consists of three different symbols i.e. 0, 1 and 2. You have to perform the following operation defined in a given expression where we have to subtract a tertiary number from a decimal number and have to express the output in a binary number system.

(576)10 – (110002)3 = (_?_)2

The galaxy is composed of the stars, satellite and planets etc. In earth’s home galaxy, the solar system is comprised of sun (average star) and objects that orbits around it. Following are the 8 largest objects (planets):

1. Mercury

2. Venus

3. Earth

4. Mars

5. Jupiter

6. Saturn

7. Uranus

8. Neptune

The first four planets are called inner planets while the remaining four are outer planets. All planets revolve around the Sun and Satellites revolve around the planet.

The tasks you have to do are:

1. Extract the main objects (entities) from the given scenario.

2. Find the necessary attributes and functions that need to be associated with each object to implement the functionality mentioned above.

3. Identify the relationships between these objects.

Suppose that you have to write a small C/C++ program where the fast execution of the program is the key requirement. The memory utilization by the program is not an issue at all. You are given two options to develop the program either using Inline functions or simple ordinary functions.

Which of these options you will choose to develop the program? Justify your answer with solid reason(s).

“Justify the following statement

If you calculate the speed of light from a star that is moving toward you, you will get a higher value than if you calculate the speed of light from a star that is moving away from you?

Either yes or no, give a solid reason for its justification”
