std::experimental::erase_if (std::multiset)

定义于头文件 `<experimental/set>`
template <class Key, class Compare, class Alloc, class Pred> void erase_if(std::multiset<Key,Compare,Alloc>& c, Pred pred);		(库基础 TS v2)

从容器擦除所有满足谓词 pred 的元素。等价于

for (auto i = c.begin(), last = c.end(); i != last; ) {
  if (pred(*i)) {
    i = c.erase(i);
  } else {
    ++i;
  }
}

c	-	要从中擦除的容器
pred	-	确定该擦除哪些元素的谓词

线性。
