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();

find() in C++ STL | GeeksforGeeks

In this article, we will learn about find () function in C++. The std::find () is a C++ STL function defined inside <algorithm> header file. Parameters: first: Iterator to the first element of range. last: Iterator to the theoretical element just after the last element of range. val: Value to be searched. Return Value:

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++ 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.

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++ find()函数用法(一般用于vector的查找) - CSDN博客

find函数主要实现的是在容器内查找指定的元素，并且这个元素必须是基本数据类型的。查找成功返回一个指向指定元素的迭代器，查找失败返回end迭代器。 cout<< "ERROR!" <<endl; find_if函数带条件的查找元素，容器元素类型是类的时候，不能使用find函数，只能通过find_if函数来实现。 find_if函数依次的遍历容器的元素，返回第一个使函数为true的元素的迭代器，如果查找失败则返回end迭代器. 文章浏览阅读10w+次，点赞46次，收藏237次。相信学习C++的人有很多人用过CString.find ()函数，但是你有么有用过 std::find () 函数呢？ find函数主要实现的是在容器内查找指定的元素，并且这个元素必须是基本数据类型的。

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++ find()函数对vector的查找-菜鸟笔记

C++ find ()函数对vector的查找. C++的find函数提供了一种对vector、string类型数据进行查找的方法。 vector<int> arr; arr.push_back(1); arr.push_back(5); arr.push_back(12); arr.push_back(7); arr.push_back(6); arr.push_back(4); //输出一下vector. for(int i=0;i<arr.size();i++){ cout<<arr[i]<<" "; cout<<endl; vector<int>::iterator it; //使用find()对vector进行查找会返回一个迭代器.
