Theset::find() functionis a predefined function, it is used to check whether an element belong to the set or not, if element finds in the set container it returns an iterator pointing to that element. The function checks whether an element belong to the set or not. If an element belong...
STL的find_if函数功能很强大,可以使用输入的函数替代等于操作符执行查找功能(这个网上有很多资料,我这里就不多说了)。 比如查找一个数组中的奇数,可以用如下代码完成(具体参考这里:http://www.cplusplus.com/reference/algorithm/find_if/): #include <iostream>#include<algorithm>#include<vector>usingnamespacestd;...

在英语口语交流中,你可能会说:“To find a specific element in a container of custom types, we need to provide an equivalence function that takes an element and a target value and returns a boolean value indicating whether the element is equal to the target value.”(要在自定义类型的容器中找到...
Learn how to use the C++ set find function to search for elements in a set. Understand its syntax, parameters, and examples for better implementation.

我们需要用到find_if函数,并自己指定predicate function谓词函数(即find_if函数的第三个参数,请查阅STL手册)。先看看find_if函数的定义: template<class InputIterator, class Predicate> InputIterator find_if(InputIterator _First, InputIterator _Last, Predicate _Pred); ...
