C++ STL set::find() function 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...

Visual C++에서 set::find STL 함수를 사용하는 방법을 설명합니다. 이 문서에는 샘플 코드가 포함되어 있습니다.
The following example shows the usage of std::set::find.Open Compiler #include <iostream> #include <set> int main () { std::set<int> myset; std::set<int>::iterator it; for (int i = 1; i <= 10; i++) myset.insert(i*10); it = myset.find(40); myset.erase (it); my...
find(20); if (it != uset.end()) { std::cout << "Element 20 found in uset." << std::endl; } else { std::cout << "Element 20 not found in uset." << std::endl; } // 删除元素 uset.erase(20); std::cout << "After erasing 20, elements in uset: "; for (int ...
如果find 的返回值赋给 const_iterator,不能修改设置的对象。 如果 find 的返回值赋给 iterator,可以修改设置的对象。示例复制 // set_find.cpp // compile with: /EHsc #include <set> #include <iostream> int main( ) { using namespace std; set <int> s1; set <int> :: const_iterator s1_Ac...
Please try to verify or disprove rules! In particular, we'd really like to have some of our rules backed up with measurements or better examples. You will find some of the rules obvious or even trivial. Please remember that one purpose of a guideline is to help someone who is less expe...
C++ STL set::find() 函數 set::find() 函數是一個預定義的函數,用於檢查一個元素是否屬於集合,如果元素在集合容器中找到,則返回一個指向該元素的迭代器。 原型: set<T> st; //declaration set<T>::iterator it; //iterator declaration it=st.find( const T item); ...
// SetFind.cpp // compile with: /EHsc // // Illustrates how to use the find function to get an iterator // that points to the first element in the controlled sequence // that has a particular sort key. // // Functions: // // find Returns an iterator that points to the first ...
