Right ANSWER is (a) namespace STD

Easiest explanation - As these are standard EXCEPTIONS, they need to be defined in the standard BLOCK, So it is defined under namespace std.

The correct answer is (a) Reduces the amount of code in cache

Explanation: COMPILERS may TRY to move the catch-code FAR AWAY from the try-code, which reduces the amount of code to keep in cache normally, thus enhancing performance.

The CORRECT CHOICE is (a) 1

For explanation: In c++ program, We can be able to throw only one error at a TIME.

Correct ANSWER is (C) class name: access specifier class name

The explanation: SYNTAX is:

class Class_Name: Access_Specifier Base_Class_Name

example:

class A{};

class B: PUBLIC A{};

The correct choice is (b) RESOURCE cleanup

The explanation is: It will be used to free all the resources that are used by the BLOCK of CODE during EXECUTION.

The CORRECT choice is (B) It can throw ANYTHING

For EXPLANATION: No EXCEPTION specification that it can throw anything.

The CORRECT choice is (d) 4

Explanation: STL has four components namely ALGORITHMS, CONTAINERS, FUNCTORS and ITERATORS.

The CORRECT CHOICE is (c) CONSTANT EXPRESSION

Easiest explanation - Non-type template parameters PROVIDE the ability to pass a constant expression at compile time. The constant expression may also be an address of a function, object or static class member.

Correct ANSWER is (a) We cannot MAKE an instance of an ABSTRACT base class

The best EXPLANATION: We cannot make an instance of an abstract base class.

The correct option is (b) ~

The BEST I can explain: TILDE(~) is USED to declare DESTRUCTOR of a CLASS.

Right option is (d) All of the mentioned

To explain: As we are using return for each and every EXCEPTION, It will DEFINITELY INCREASE the code SIZE.

Right OPTION is (c) RETURN

Easiest EXPLANATION - throw and return does the same job as return a VALUE. So it can be replaced.

The correct OPTION is (a) A PROBLEM that arises during the execution of a program

Explanation: An EXCEPTION is defined as the problem in C++ program that arises during the execution of the program for example DIVIDE by zero error.

Right CHOICE is (d) CONTAINERS that provide a different interface for sequential containers

Easy EXPLANATION - Container Adaptors is the subset of Containers that provides a different interface for sequential containers.

The correct option is (a) class contains OBJECTS of other class TYPES as its members

The best explanation: CONTAINER ship is a class contains objects of other class types as its members.

The CORRECT answer is (a) OVERRIDING REFERS to a derived class function that has the same name and SIGNATURE as a base class virtual function

The BEST explanation: Overriding refers to a derived class function that has the same name and signature as a base class virtual function.

Correct choice is (a) public

For explanation: If we invoked the INTERFACE as public MEANS, We can ACCESS the program from other PROGRAMS also.

Right option is (a) We have to THROW an EXCEPTION

For explanation: As a constructor don’t have a RETURN type, We have to throw the exception.

Correct answer is (C) 4

Best EXPLANATION: C++ PROVIDES 4 TYPES of Associative Containers namely Set, Map, multiset and multimap.

Correct OPTION is (B) =0

To EXPLAIN I would say: For making a method as PURE virtual FUNCTION, We have to append ‘=0’ to the class or method.

Correct OPTION is (a) 9

The BEST EXPLANATION: There are nine standard exceptions in c++. They are bad_alloc, bad_cast, bad_exception, bad_function_call, bad_typeid, bad_weak_ptr, ios_base::failure, logic_error and runtime_error.

The correct answer is (b) USE the stack

The BEST I can explain: When an error is raised MEANS, it will be pushed into stack and it can be CORRECTED LATER by the programmer.

Correct OPTION is (a) arise an error

Explanation: If try catch BLOCK is not used the EXCEPTION THROWN by the program will be uncaught hence will result into error(s).

Right answer is (a) type-safe

Easiest explanation - The compiler can determine at compile TIME WHETHER the type ASSOCIATED with a TEMPLATE DEFINITION can perform all of the functions required by that template definition.

Correct CHOICE is (B) 2

The best explanation: There are two kinds of CLASSES in c++. They are absolute CLASS and the concrete class.

Right answer is (B) Class specifically used as a base class with atleast one PURE VIRTUAL functions

Easy explanation - An abstract class is defined as a class which is specifically used as a base class. An abstract class should have atleast one pure virtual FUNCTION.

Right choice is (B) arise an error

To explain I would say: Because there is no way defined to catch that exception and as we know if an exception is not CAUGHT then error ARISES.

Correct option is (a) VIOLATION of syntactic and semantic RULES of a languages

To explain I would SAY: An error occurs when rules and laws of a LANGUAGE is violated while writing PROGRAMS in that language.

The correct CHOICE is (c) exception handler

Explanation: Exception handler is USED to HANDLE the exceptions in c++.

Right answer is (d) Exception

The EXPLANATION is: If there is any mishap in MEMORY or resource management means, the problems that are MENTIONED above can HAPPEN.

Correct choice is (d) 5

The explanation is: C++ PROVIDES 5 types of Sequence Containers NAMELY ARRAY, vector, deque, forward_list and list.

The correct OPTION is (a) Containers that IMPLEMENTS data STRUCTURES which can be accessed sequentially

To explain: Sequence Containers is the subset of Containers that implements data structures which can be accessed sequentially.

The CORRECT CHOICE is (a) Function which does not have DEFINITION of its own

The explanation is: As the name itself implies, it have to DEPEND on other CLASS only.

The CORRECT ANSWER is (a) #include

Best explanation: #include is USED to declare the STANDARD exception.

The correct CHOICE is (B) Deriving a class from more than one direct base class

The best explanation: In MULTIPLE INHERITANCES, We are able to DERIVE a class from more than one base class.

The CORRECT OPTION is (c) Pure virtual function is implemented in derived classes

The explanation is: A pure virtual function does not have a definition CORRESPONDING to base CLASS. All derived class may or may not have an implementation of a pure virtual function. there is no pure keyword in C++.

Correct answer is (c) 3

To EXPLAIN: The THREE levels of EXCEPTION safety are basic, STRONG and no throw.

Right ANSWER is (c) Establish the class invariant

The best I can explain: The purpose of a constructor is to establish the class invariant. To do that, it often NEEDS to acquire SYSTEM resources or in general PERFORM an operation that MAY fail.

Correct choice is (b) The form of AUTOMATIC memory management

The best I can explain: The garbage collection attempts to reclaim memory occupied by OBJECTS that are no longer in USE by the PROGRAM.
