    Answer: A

2. Which statement is true about a static nested class?

    A.You must have a reference to an instance of the enclosing class in order to instantiate it.
    B.It does not have access to nonstatic members of the enclosing class.
    C.It's variables and methods must be static.
    D.It must extend the enclosing class.

    Answer: B

    Option B is correct because a static nested class is not tied to an instance of the enclosing class, and thus can't access the nonstatic members of the class (just as a static method can't access nonstatic members of a class). Option A is incorrect because static nested classes do not need (and can't use) a reference to an instance of the enclosing class. Option C is incorrect because static nested classes can declare and define nonstatic members. Option D is wrong because it         just is. There's no rule that says an inner or nested class has to extend anything.

3. Which constructs an anonymous inner class instance?

 A.Runnable r = new Runnable() { };                                                            B.Runnable r = new Runnable(public void run() { });                                    C.Runnable r = new Runnable { public void run(){}};    D.System.out.println(new Runnable() {public void run() { }});

    Answer: D

    D is correct. It defines an anonymous inner class instance, which also means it creates an instance of that new anonymous class at the same time. The anonymous class is an implementer of the Runnable interface, so it must override the run()method of Runnable. A is incorrect because it doesn't override the run() method, so it violates the rules of interface implementation. B and C use incorrect syntax.

4. Which of the following range is a valid long double?

    A.3.4E-4932 to 1.1E+4932        B.3.4E-4932 to 3.4E+4932            C.1.1E-4932 to 1.1E+4932            D.1.7E-4932 to 1.7E+4932

    Answer: A

    The range of long double is 3.4E-4932 to 1.1E+4932

5. In C, if you pass an array as an argument to a function, what actually gets passed?

    A.Value of elements in array        B.First element of the array        C.Base address of the array        D.Address of the last element of array

    Answer: C

    The statement 'C' is correct. When we pass an array as a funtion argument, the base address of the array will be passed.

6. Consider the following program:
    # include
    class x
            int a;
             a=10; cout<
            class b:public x

7.     int i,j;

    A.Runtime error        B.6            C.5            D.10

    Answer: A

    Runtime error: Abnormal program termination. assert failed (i<5), , asserts are used during debugging to make sure that certain conditions are satisfied. If assertion fails, the program will terminate reporting the same. After debugging use,  #undef NDEBUG and this will disable all the assertions from the source code. Assertion is a good debugging tool to make use of.
