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、...
std::set<T> 元素的序列由 T const 对象组成。实际上,我们昨天在标准 C++ 委员会上讨论了这个问题,并且支持创建专门处理 erase() 来自容器的对象的算法。它看起来像这样(另见 N4009): template <class T, class Comp, class Alloc, class Predicate> void discard_if(std::set<T, Comp, Alloc>& c, ...
cout << "After the 2nd element is deleted, the set s1 is:"; for (pIter = s1.begin(); pIter != s1.end(); pIter++) cout << " " << *pIter; cout << "." << endl; // The 2nd member function removes elements // in the range [_First, _Last) Iter1 = ++s2.begin(); I...
The first member function removes the element of the controlled sequence pointed to by where, and returns an iterator that designates the first element remaining beyond the element removed, or set::end (STL/CLR)() if no such element exists. You use it to remove a single element. The second...
void Remove3(std::set<int>& sets) std::set<int>::iterator iter = sets.begin(); while (iter != sets.end()) if (0 == (*iter)%2) // 注意这里不能写成++iter,后面说明原因 sets.erase(iter++); else ++iter; void Remove4(std::map<int, int>& maps) ...

Write a simple utility function to run and display the output of a pipeline instance [2]: defshow(pipe):pipe.build()out=pipe.run()plt.imshow(out[0].at(0)) We can now use the pipeline to demonstrate the different use cases of the erase operator. ...

:is_transparentare valid and each denotes a type, and neitheriteratornorconst_iteratoris implicitly convertible fromK. This assumes that suchHashis callable with bothKandKeytype, and that theKeyEqualis transparent, which, together, allows calling this function without constructing an instance ofKey....
