How to find out if an item is present in a std::vector?

You pass the std::find function the begin and end iterator from the vector you want to search, along with the element you're looking for and compare the resulting iterator to the end of the vector to see if they match or not. std::find(vector.begin(), vector.end(), item) != vector.end()

Exceptions. The overloads with a template parameter named ExecutionPolicy report errors as follows: . If execution of a function invoked as part of the algorithm throws an exception and ExecutionPolicy is one of the standard policies, std::terminate is called. For any other ExecutionPolicy, the behavior is implementation-defined.; If the algorithm fails to allocate memory, std::bad_alloc is ...

C++ Vector Find: Mastering Element Search in C++

Master the art of c++ vector find with our concise guide. Uncover tips and tricks to swiftly locate elements in your vectors. 880. In C++, the `std::find` algorithm can be used to locate an element within a vector, returning an iterator to the found element or the end iterator if the element is not present.

C++ Tutorial => Finding an Element in std::vector

Example. The function std::find, defined in the <algorithm> header, can be used to find an element in a std::vector.. std::find uses the operator== to compare elements for equality. It returns an iterator to the first element in the range that compares equal to the value. If the element in question is not found, std::find returns std::vector::end (or std::vector::cend if the vector is const).

How to Find Index of a Given Element in a Vector in C++?

Vectors stores elements in contiguous memory and these elements can be accessed by their indexes. In this article, we will learn the reverse process, i.e., finding the index of the given element in a vector in C++. The simplest way to find the index of the given element in the vector is by using find() function. Let’s take a look at a simple ...
