Title: Unit 4: JNTUK R20 Syllabus-Based Standard Template Library in C++
Overview
One of C++'s most useful features is the Standard Template Library (STL), which offers pre-made templates for a wide range of data structures and algorithms. We'll talk about the STL in C++ programming in Unit 4 of the JNTUK R20 syllabus in this blog article.
The JNTUK R20 syllabus's fourth unit is all about C++ programming's Standard Template Library (STL). With the help of the robust STL feature of C++, programmers may create code that is both optimized and efficient by using pre-defined templates for a variety of data structures and algorithms.
Students study the many STL components in this subject, such as allocators, containers, iterators, and algorithms. They Discover the several kinds of STL containers—vectors, lists, sets, and maps, among others—and how to utilize them for data manipulation and storing.
Data structures called containers are used to store a group of things. Sequence containers, associative containers, and unordered associative containers are among the various kinds of containers that the STL offers. Associative containers sort data according to a key, whereas sequence containers store data in a predetermined order. Data is stored in unsorted associative containers according to a hash function.
Students gain knowledge of the various kinds of sequence containers, including lists, deques, and vectors, as well as how to store and manage data using them. Dynamic arrays with the ability to self-resize are called vectors, whereas deques are queuing systems with two ends that permit items to be added or removed. Lists are linked lists that make it easy to add and remove elements.
Additionally, students study the various forms of associative containers, including sets and maps, and how to store and manage data with them. Maps are collections of key-value pairs, and sets are sorted collections of unique components.
Students also study about iterators, which are utilized to navigate and work with the components of containers. They study the numerous kinds of iterators and discover how to apply them with different containers. These include input, output, forward, and bidirectional iterators.
Pointers to the components of containers are what iterators are. They offer a means of obtaining and change the components of containers without disclosing the implementation below. The use of iterators to navigate between container elements, retrieve their values, and alter them is taught to students.
Students also gain knowledge of the several algorithms offered by the STL, including algorithms for sorting, searching, and manipulation. They study the many kinds of algorithms and learn how to apply them with different containers and iterators. Examples of these are sort, binary_search, and reverse.
Functions that carry out actions on containers and their constituent parts are called algorithms. Numerous algorithms, such as those for sorting, searching, and manipulation, are available in the STL. Students gain knowledge of how to sort, search, and work with the components of containers using these techniques.
Finally, allocators—which are used to manage memory—are taught to the pupils container allocation and deallocation. They study the many kinds of allocators and discover how to apply them with different containers. Examples of these are default and custom allocators.
The objects that control memory allocation and deallocation for containers are called allocators. Most containers use the default allocator provided by the STL. In order to manage memory in a particular fashion, for as by using a memory pool or a custom memory manager, students are taught how to design custom allocators.
