Question: Which STL We can insert remove data from anywhere?

What is STL list different types of STL containers?

The three types of containers found in the STL are sequential, associative and unordered.

Unordered (associative) Containers

  • unordered_set.
  • unordered_multiset.
  • unordered_map.
  • unordered_multimap.

What kind of iteration does Forward_list provide in C++?

What kind of iteration does forward_list provide in C++? Explanation: The forward_list uses singly linked list hence it is uni-directional. In the forward_list, the container provides insertion and removal at anywhere in the program.

What do all STL containers define?

An STL container is a collection of objects of the same type (the elements). Container owns the elements. Creation and destruction is controlled by the container.

Which method or methods from the std :: list class can delete all the elements from the collection in one call Choose all that apply?

list::clear() is an inbuilt function in C++ STL which is declared in header file. list::clear(), clears the whole list. In other words the clear() removes all the elements present in the list container and leaves the container with size 0.

What are the three components of STL?

STL mainly consists of the following components which are mentioned below:

  • #1) Containers. A container is a collection of objects of a particular type of data structure. …
  • #2) Algorithms. …
  • #3) Iterators. …
  • #1) Sequential Containers. …
  • #2) Associative Containers. …
  • #3) Container Adopters.

What are STL algorithms?

The Standard Template Library, or STL, is a C++ library of container classes, algorithms, and iterators; it provides many of the basic algorithms and data structures of computer science. The STL is a generic library, meaning that its components are heavily parameterized: almost every component in the STL is a template.

What kind of exceptions are used in C++?

There are two types of exceptions: a)Synchronous, b)Asynchronous(Ex:which are beyond the program’s control, Disc failure etc). C++ provides following specialized keywords for this purpose. try: represents a block of code that can throw an exception.

Which operator is used to insert the data into file?

Which operator is used to insert the data into file? Explanation: You can write information to a file from your program using the stream insertion operator <<.

What alternative can replace throw statement?

Which alternative can replace the throw statement? Explanation: throw and return does the same job as return a value. So it can be replaced.

What does STL stand for?

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. … This is the only way to ensure full performance for containers that do not need concurrent access.

How are STL containers implemented?

Different containers have different guarantees. The vector, for example, must be implemented as a contiguous array in memory. Mostly though the containers are specified in terms of how they behave wrt time complexity and interface. @user4581301: Realistically though, a std::deque might adapt to the cache line length.
