C++ STL set::erase() function: Here, we are going to learn about the erase() function of set in C++ STL (Standard Template Library).
myset.erase(it1, it2); //Printing the set for ( auto it = myset.begin(); it != myset.end(); ++it) cout <<' ' <<*it; return 0; } 输出如下: E G 删除范围内的元素 //INTEGER SET EXAMPLE //CPP program to illustrate //Implementation of erase() function #include <iostream> ...
set.erase(first,last);// 删除[first, last)范围内的元素 三、根据值删除元素 要根据值删除set中的元素,可以使用erase函数的第一种形式,即传入一个特定的值作为参数。erase函数会删除set中所有值等于给定值的元素。 std::set<int>mySet{1,2,3,4,5}; mySet.erase(3);// 删除set中值为3的元素 四、...
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...

返回值:An iterator pointing to the element that followed the last element erased by the function call. This is thecontainer endif the operation erased the last element in the sequence. remove: 说明:Remove elements with specific value。Removes from the container all the elements that compare equal...
