In a P-Type semiconductor, the Fermi level in 0.3 eV above the valance band at a room temperature of 300 oK. Determine the new position of the Fermi level for temperature of a (350 oK) and (b) 400 oK.
A system is defined by its impulse response [ ] 2 2 ( ) n h n u n = − . Discuss whether the system is stable, causal, or unstable and non-causal? Support your answer? (5)
attributes name, for person name, as a character array of size 50 and age, for a
person’s age as a positive integer.
Create three classes —House, Car and Mobile.
o House class should have attributes of area and location.
o Car class should have attributes of color and registration number.
o Mobile class should have attribute of model.
o Write an abstract class PollutionEffect with only a pure virtual getPollutionEffect method.
o Each of the three classes should inherit from this abstract class and implement the
getPollutionEffect method to print an appropriate pollution effect count for that class.
o The getPollutionEffect of House class should print “one”, Car class should print “Two” and
Mobile class should print “Three”.
o Write an application that creates objects of each of the three classes, places pointers to those
objects in a array of PollutionEffect pointers, then iterates through the array, invoking each
object’s getPollutionEffect method.
Question No. 2: Answer the following questions? ( 15 Marks ) [ CLO2 ]
Make a class named Person
o It has two attributes name, for person name, as a character array of size 50 and age, for a
person’s age as a positive integer.
o Make a function named get() to get a person’s name and age from user.
o Make a function named show() to show a person’s name and age on screen.
o Make a child class named Student and privately inherit this class from Person class.
o It has one attribute gpa, as a float data type.
o Make a function named get() to get name, age and gpa of a student from user.
o Make a function named show() to show the name, age and gpa of a student on screen.
o In the main() function make a Student object and call get() and show() functions through this
object and close the program.
