It demands a lot of code to achieve the desired output. The standard template library, or STL, can help you solve this conundrum. Considering the amount of time and effort consumed while writing code for functions like sorting and searching, STL can help you perform all these operations with just a single line of code.
This library can be immensely useful for problem-solving and technical interview preparation. It includes some prominent template classes for common data structures like vectors, stacks, queues, and some handy algorithmic functions like binary search to make programming easier.
Let's take a look at the algorithms and containers in greater depth, as those are the most commonly used components of the STL. Some of the algorithms included are binary search, sorting, and reverse, which are extremely useful. The syntax is as follows:. The sort function helps you sort all the elements inside the specified data structure in ascending order. This function takes two parameters: the starting iterator and the ending iterator.
The reverse function reverses the order of elements in the specified data structure. It accepts two parameters: the starting iterator and the ending iterator. Both these functions accept two arguments: the start iterator and the end iterator.
It accepts three arguments: the starting iterator, the ending iterator, and the value that you want to find. Binary search only works on sorted data structures. The count method returns the count of occurrence of the specified value inside the data structure.
It takes three arguments: the start iterator, the end iterator, and the value to count. Containers are the data structures that store objects and data.
Vectors, lists, stacks, queues, sets, and maps are some of the examples that store data in them according to the specified primitive datatype. Vectors are dynamic arrays that are resizable and flexible to work with. When you insert or delete an element from the vector, it automatically adjusts the vector's size.
It is a kind of blueprint and a generalized class which contains all the parametrized components. For working with the standard template library, it is very much needed to work with the components and features of template classes. We can take into consideration all the factors such as:. Standard Template Libraries contain template libraries which in turn makes use of some important components which cannot be ignored.
These are kind of predefined functions which makes use of essential components:. Algorithms are the set of instructions or kind of pseudocode which is used to get the blueprint of the flow of execution of programs. Sorting: Sorting is a kind of very common function used by any data residing within the container.
It makes use of a built-in function that works in a fashion to make the data arranged in increasing or decreasing fashion. It makes use of a function called sort. Binary Search: Searching is a task used to find for the desired element.
It is very much needed to perform a sorting before any searching is applied. Algorithm: Within the standard template, the library plays a very important role in the sense it makes use of certain very important algorithms on vectors like:. Containers, as its name suggests, make use of classes within the container to store various objects and data. It is used for working on a sequence of values. Functions include that can overload any function with call operator.
Such types of classes have special instances which are called as function objects.
