C++ set erase() 函数用于从集合容器中删除与给定键关联的单个元素或一系列元素 ([first, last))。因此,大小将因删除的元素数量而减少。 用法 voiderase(iterator position);//until C++ 11size_typeerase(constvalue_type& val);//until C++ 11voiderase(iterator first, iterator last);//until C++ 11iterat...
CPP unordered_set erase() function in C++ STL unordered_set::erase() 函数是 C++ STL 中的内置函数,用于删除从开始(包括)到结束(不包括)的单个元素或一组元素)。这会通过删除的元素数量来减小容器的大小。注意:unordered_set 中的桶编号从 0 到 n-1,其中 n 是桶的总数。语法:可以三种方式声明, Method...
In the example below, theunordered_set::erasefunction is used to delete a single element fromuSet. #include<iostream>#include<unordered_set>usingnamespacestd;intmain(){unordered_set<int>uSet{10,20,30,40,50};unordered_set<int>::iterator it;cout<<"uSet contain: ";for(it=uSet.begin()...

当使用反向迭代器调用erase()时,可以遵循以下步骤: 1. 确保您已经创建了一个反向迭代器,可以通过使用`reverse_iterator`构造函数来实现。 2. 调用`erase()`方法,传...
erase("hello"); // 输出删除后的集合 cout << "删除后的集合为:" << endl; for (const auto& x : myset) { cout << x << " "; } cout << endl; return 0; } ``` 上述示例代码中,我们分别使用了erase()函数的两种不同语法,一种是删除单个元素(键为"world"的元素),一种是删除所有...
