参数返回值 remove_if(begin,end,op); 前两个参数:表示迭代的起始位置和这个起始位置所对应的停止位置【迭代器】。 最后一个参数:传入一个回调函数,如果回调函数返回为真,则将当前所指向的元素移到尾部。 返回值:被移动到某个区域的首个目标元素 iterator,将此删除即实现了将要删除的元素删除的目的 头文件 #i

remove():删除具有给定值的元素。 remove_if():删除满足谓词的元素。 remove_copy():复制序列时删除具有给定值的元素。 remove_copy_if):复制序列时删除满足谓词的元素。 remove函数模板的行为等效于: template <class ForwardIterator, class T> ForwardIterator remove (ForwardIterator first, ForwardIterator last,...
Each condition is evaluated individually for each record, and the record is removed if all conditions evaluate to true. Remove and RemoveIf return the modified data source as a table. You can use both functions only in behavior formulas. You can also use the Clear function to remove all of ...
