What does derived class does not inherit from the base class?
A derived class can access all the non-private members of its base class.
Thus base-class members that should not be accessible to the member functions of derived classes should be declared private in the base class.
Constructors, destructors and copy constructors of the base class..
What is a class template?
Class templates A class template provides a specification for generating classes based on parameters. Class templates are generally used to implement containers. A class template is instantiated by passing a given set of types to it as template arguments.
How are STL containers implemented?
Classification of Containers in STL Containers are classified into four categories : Sequence containers : Used to implement data structures that are sequential in nature like arrays(array) and linked list(list). Associative containers : Used to implement sorted data structures such as map, set etc.
Is new thread safe C++?
Generally the new operator is thread safe – however thread safety guarantees for calls into the STL and the standard library are governed by the standard – this doesn’t mean that they are thread unaware – they tend to have very well defined guarantees of thread safety for certain operations.
Is an array a container?
Arrays are fixed-size sequence containers: they hold a specific number of elements ordered in a strict linear sequence. Internally, an array does not keep any data other than the elements it contains (not even its size, which is a template parameter, fixed on compile time).
What is a bag in C++?
A Static Bag Container Class In C++, container classes can be implemented as a class, along with member functions to add, remove, and examine items. The Bag Class Abstraction. … This is a class where each object can contain a collection of items (such as numbers).

Can we use STL in coding interviews?
Originally Answered: Is it acceptable to use STL library in coding interview? Depends on Question. If you are asked a question related to designing something then your Knowledge about OOPS is being tested so in such cases you can use STL . … Because interviewer want to see your problem solving.
Is C++ STL thread safe?
The SGI implementation of STL is thread-safe only in the sense that simultaneous accesses to distinct containers are safe, and simultaneous read accesses to to shared containers are safe.
What are the containers in C++?
Containers in C++ STLSequence containers (array, vector, list)Associative containers (set, map, multimap)Unordered Associative containers (unordered_set, unordered_map)Container Adapters (stack, queue)
What are container adapters?
Container adaptors are not full container classes, but classes that provide a specific interface relying on an object of one of the container classes (such as deque or list) to handle the elements.
What is thread safe C++?
An object is thread-safe for reading from multiple threads. For example, given an object A, it is safe to read A from thread 1 and from thread 2 simultaneously. … It is safe to read and write to one instance of a type even if another thread is reading or writing to a different instance of the same type.
Which data structure is used in C++ STL implementation?
The standard container adapters are: stack provides an LIFO data structure. queue provides a FIFO data structure. priority_queue provides a priority queue, which allows for constant-time lookup of the largest element (by default)
What is container in data structure?
In computer science, a container is a class, a data structure, or an abstract data type (ADT) whose instances are collections of other objects. In other words, they store objects in an organized way that follows specific access rules. The size of the container depends on the number of objects (elements) it contains.
What is a container class?
A container class is a class that can hold a collection of items. Container classes can be implemented with a C++ class. The class is implemented with a header file (containing documentation and the class definition) and an implementation file (containing the implementations of the member functions).
What two types of containers does the STL provide?
Two basic types of containers:Sequences. User controls the order of elements. vector, list, deque.Associative containers. The container controls the position of elements within it. Elements can be accessed using a key. set, multiset, map, multimap.
What is container and its types in C++?
Last Updated: 12-07-2020. A container is a holder object that stores a collection of other objects (its elements). They are implemented as class templates, which allows a great flexibility in the types supported as elements.
What is the purpose of iterator?
The primary purpose of an iterator is to allow a user to process every element of a container while isolating the user from the internal structure of the container. This allows the container to store elements in any manner it wishes while allowing the user to treat it as if it were a simple sequence or list.
What are the components of STL in C++?
The Standard Template Library (STL) is a software library for the C++ programming language that influenced many parts of the C++ Standard Library. It provides four components called algorithms, containers, functions, and iterators.
What are the types of associative containers?
Types of Sequence Containers In the C++ Standard Library, there are four ordered associative containers and four unordered associative containers. The four ordered associative containers are multiset, set, multimap, and map.
What is STL containers in C++?
The Standard Template Library (STL) is a set of C++ template classes to provide common programming data structures and functions such as lists, stacks, arrays, etc. It is a library of container classes, algorithms, and iterators. It is a generalized library and so, its components are parameterized.
