Find value in range - C++ Users
Input iterators to the initial and final positions in a sequence. The range searched is [first,last), which contains all the elements between first and last, including the element pointed by first but not the element pointed by last. Value to search for in the range.

How to find out if an item is present in a std::vector?
So a better title would be "How to find an item in a std::vector, if it exists?" Or something like that. You can use std::find from <algorithm>: This returns an iterator to the first element found. If not present, it returns an iterator to one-past-the-last. With your example: do_this(); do_that();

std::find, std::find_if, std::find_if_not - cppreference.com
Returns an iterator to the first element in the range [first,last) that satisfies specific criteria (or last if there is no such iterator). 1)find searches for an element equal to value (using operator==). 3)find_if searches for an element for which predicate p returns true. 5)find_if_not searches for an element for which predicate q returns false.

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. 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. std::vector<int> vec = {1, 2, 3, 4, 5};

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

C++ algorithm find() function - W3Schools
The find() function returns an iterator pointing to the first occurrence of a specified value in a data range. If the value is not found then it returns the iterator pointing to the end of the data range. The range of data is specified by iterators. <type> refers to the type of the data that the range contains. Required.

vector - C++ Users
Vectors are sequence containers representing arrays that can change in size. Just like arrays, vectors use contiguous storage locations for their elements, which means that their elements can also be accessed using offsets on regular pointers to its elements, and just as efficiently as in arrays.

Efficient Element Finding with std::find in C++ Vectors - MyScale
In the realm of C++, the std::find function stands out as a powerful tool for searching elements within vectors. Let's dissect its functionality and explore practical examples to grasp its significance. The std::find function operates by sequentially comparing each element in the vector with a specified value until a match is found.
