• Question 75:

  How many parameters can a default constructor have?

  A. 0

  B. 1

  C. 2

  D. 3 or more

  Correct Answer: A

  If a class contains no instance constructor declarations, a default instance constructor is automatically provided. That default constructor simply invokes the parameterless constructor of the direct base class.

  A. Mybase.brake ()

  B. Truck.brakef)

  C. Vehicle.brake()

  D. Me.brake ()

  Correct Answer: A

  The MyBase keyword behaves like an object variable referring to the base class of the current instance of a class.MyBase is commonly used to access base class members that are overridden or shadowed in a derived class.

• Question 77:

  Which type of function can a derived class override?

  A. A Protected Overridable member function

  B. A Shared function

  C. A Private Overridable function

  D. A non-overridable public member function

  Correct Answer: A

  The Overridable modifier allows a property or method in a class to be overridden in a derived class. You cannot specify Overridable or NotOverridable for a Private method.

• Question 78:

  C. m1, m3, m4

  D. m1, m2, m3

  F. only m3, m4

  Correct Answer: D

• Question 79:

  You execute the following code.

  

  How many times will the word Hello be printed?

  A. 49

  B. 50

  C. 51

  D. 100

  Correct Answer: B

  The mod operator computes the remainder after dividing its first operand by its second. All numeric types have predefined remainder operators. In this case the reminder will be nonzero 50 times (for i with values 1, 3, 5,..,99).

• Question 80:

  The purpose of the Finally section in an exception handler is to:

  A. Execute code only when an exception is thrown.

  B. Break out of the error handler.

  C. Execute code regardless of whether an exception is thrown.

  D. Conclude the execution of the application.

  Correct Answer: C

  By using a finally block, you can clean up any resources that are allocated in a try block, and you can run code even if an exception occurs in the try block. Typically, the statements of a finally block run when control leaves a try statement. The transfer of control can occur as a result of normal execution, of execution of a break, continue, goto, or return statement, or of propagation of an exception out of the try statement.
