Sample EC6301 Object Oriented Programming and Data Structures important questions:

1. Difference between Class and structure? [April -2010, Dec-2012]

Class is the ADT where as structure is udt. Class needs access specifier such as private, public & private where as structure members can be accessed by public by default & don’t need any accessfiers. Class is oops where structure is borrowed from traditional structured [pop] concept.

2. What is abstract Class? [Nov-2009]

An abstract class is a class that is designed to be specifically used as a base class. An abstract class contains at least one pure virtual function. You declare a pure virtual function by using a pure specifier [= 0] in the declaration of a virtual member function in the class declaration. (EC6301 Object Oriented Programming and Data Structures important questions)

3. List out the advantages of new operator over malloc[] [Dec-2012]

It automatically computes the size of the data object.
It automatically returns the correct pointer type
It is possible to initialize the objects while creating_ the memory space.
It can be overloaded.

4. What are the basic concepts of OOS? [ April -2011]
Objects.
Classes.
Data abstraction and Encapsulation.
Inheritance.
Polymorphism.
Dynamic binding.
Message passing (EC6301 Object Oriented Programming and Data Structures important questions)

5. What is the difference between local variable and data member? [Nov-2011]

A data member belongs to an object of a class whereas local variable belongs to its current scope. A local variable is declared within the body of a function and can be used only from the point at which it is declared to the immediately following closing brace. A data member is declared in a class definition, but not in the body of any of the class member functions. Data members are accessible to all member function of the class. (EC6301 Object Oriented Programming and Data Structures important questions)

Sample EE6352 Electrical Engineering and Instrumentation Important questions

1. How will you find the direction of emf using Fleming’s Right Hand Rule?

The thumb, the forefinger and the middle finger of the right hand are held so that these fingers are mutually perpendicular, then Forefinger – Field Thumb – Motion Middle finger- I, current

2. How will you find the direction of force produced using Fleming’s Left Hand
Rule?

The thumb , forefinger and middle finger of the left hand are held so that those fingers are mutually perpendicular then Forefinger – Field Thumb – Motion(due to force) Middle finger – I, current (ee6352 electrical engineering and instrumentation Important questions)

3. How are armature windings classified based on the placement of the coil inside the armature slots?

Single layer winding and Double layer winding

4. Write down the emf equation for d.c generator.

E = (фNZ / 60)(P/A) V Where P= number of poles Z= Total number of conductors
A= number of parallel paths Ф= flux per pole N= speed in rpm

5. Why the armature core in d.c machines is constructed with laminated steel sheets instead of solid steel steel?

Steel sheets offer low relutance path for the magnetic field , laminated sheets reduce eddy current loss. (ee6352 electrical engineering and instrumentation Important questions)

6. Why is commutator employed in d.c machines?

• Conduct electricity between armature and fixed brushes
• Converts altenatingemf into unidirectional emf and vice versa

7. Distinguish between shunt and series field coil constructions.

Shunt field coils are wound with wires of small cross section and have more number of turns. Series field coils are wound with wires of larger cross section and have less number of turns. (ee6352 electrical engineering and instrumentation Important questions)
