Question 1

How many kinds of entities are directly parameterized in c++?

Accepted Answer

C++ allows us to parameterize directly three kinds of entities through templates: types, constants, and templates.

Question 2

Where does the exceptions are used?

Accepted Answer

Exceptions are used when postconditions of a function can be satisfied.

Question 3

Where does the exception are handled?

Accepted Answer

outside the regular code

Question 4

What are the operators available in dynamic memory allocation?

Accepted Answer

new and delete operators are mainly used to allocate and deallocate during runtime.

Question 5

Why is it expensive to use objects for exception?

Accepted Answer

If an error occurs in program, then only exception object is created otherwise, It will not be created. So it’s expensive to use in the program.

Question 6

Where does the standard exception classes are grouped?

Accepted Answer

:As these are standard exceptions, they need to be defined in the standard block, So it is defined under namespace std.

Question 7

What will happen when introduce the interface of classes in a run-time polymorphic hierarchy?

Accepted Answer

Separation of interface from implementation

Question 8

What of the following describes protected access specifier?

Accepted Answer

The variable is visible to its block and to it’s derived class

Question 9

What is the Run-Time Type Information?

Accepted Answer

With the help of RTTI, We can get the information about the data type at the runtime.

Question 10

Which is best for coding the standard libary for c++?

Accepted Answer

All of the mentioned

Question 11

How the member functions in the container can be accessed?

Accepted Answer

The container manages the storage space for its elements and provides member functions to access them, either directly or through iterators which reference objects with similar properties to pointers.

Question 12

What does the sequence adaptor provide?

Accepted Answer

Interface to sequence container

Question 13

How many items are presented in the associate container?

Accepted Answer

There are 5 items presented in the associate container. They are set, multiset, map, multimap and bitset.

Question 14

How many parameters are present in mismatch method in non-sequence modifying algorithm?

Accepted Answer

There are four parameters. They are first1, last1, first2, predicate.

Question 15

What kind of object is modifying sequence algorithm?

Accepted Answer

It is a group of functions and implemented under algorithm header file.

Question 16

What is the kind of execution does sequence point allow?

Accepted Answer

To resolve all the side-effects in the program, the sequence point should not be overlapped.

Question 17

Which keyword is used to declare the min and max functions?

Accepted Answer

Algorithm header file contain the supporting files needed for the execution of these functions.

Question 18

How the different permutations are ordered in c++?

Accepted Answer

Compare lexicographicaly to each other elements

Question 19

Where does the allocaters are implemented?

Accepted Answer

Allocaters are implemented in C++ standard library but it is used for C++ template library.

Question 20

Explain storage qualifiers in C++

Accepted Answer

i) Const - This variable means that if the memory is initialised once, it should not be altered by a program ii) Volatile - This variable means that the value in the memory location can be altered even though nothing in the program code modifies the contents iii) Mutable - This variable means that a particular member of a structure or class can be altered even if a particular structure variable, class, or class member function is constant
