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、...
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...
从1中,我们可以看到erase的返回值是iterator。An iterator pointing to the element that followed the last element erased by the function call(指向erase元素的后一个元素的迭代器)。 于是我们有了以下清除方法: 1#include"Allinclude.h"23intmain()4{56cout<<endl<<"map:"<<endl;7map<char,int>mymap;8...
set和map是由红黑树来实现的,当erase的时候迭代器就失效了,也就是说我们要在迭代器失效之前保留一个副本,根据这个副本我们才能继续遍历下一个元素。i++和++i很明显前者符合我们的要求所以在erase里面是iter++
