FunctionDescriptionSyntax (consider 'list' is the name of any integer list)empty()Checks whether given list is empty or not. It returns 1 (true) if list is empty else it returns 0 (false).list.empty();size()Returns size of the listlist.size();sort()Sorts the list in ascending orderlist.sort();reverse()Reverses the list (elements of the list)list.reverse();remove()Removes all occurrences of given elements from the list.list.remove(element);remove_if()Remove set of the elements based on the test condition (if test condition is true for the element, element will be removed and it is applicable on all the occurrences of the element which satisfy the test condition).list.remove_if(test_condition);front()Returns the first element of the listlist.front();back()Returns the last element of the listlist.back();push_front()Inserts the element at the front (beginning) to the listlist.push_front(element);push_back()Insert the element at the back (end) to the listlist.push_back(element);pop_front()Removes the element from the front (beginning) of the listlist.pop_front();pop_back()Removes the element from the back (end) of the listlist.pop_back();insert()Inserts the element at specified index/position list.insert(iterator_position, element);OR list.insert(iterator_positon, number_of_elements, element); begin() and end()Return the iterator pointing first and last element of the listlist.begin(); and list.end();rbegin() and rend()Return the iterator pointing first and last element of the list (in reverse order) i.e. first element will be considered as last and last will be consider as first list.rbegin(); and list.rend();assign()Assigns the new set of elements or replaces the current with the new set of elementslist.assign(n, element)//will assign ‘element’, ‘n’ times to the listmerge()It merges two lists.list1.merge(list2);unique()It removes consecutive elements from the list.list.unique();erase()It removes the specified index or index from the given range (index1, index2), this function can be used by defining the positions using iterator. list.erase(iterator_position); OR list.erase(iterator_position1, iterator_position2);

功能  描述  语法(考虑“列表”为任何整数列表的名称)  空()  检查给定列表是否为空。 如果列表为空，则返回1(真)，否则返回0(假)。  list.empty();  尺寸()  返回列表的大小  list.size();  分类()  按升序对列表进行排序  list.sort();  逆转()  反转列表(列表的元素)  list.reverse();  去掉()  从列表中删除所有出现的给定元素。  list.remove(element);  remove_if()  根据测试条件删除元素集(如果元素的测试条件为true，则元素将被删除，并且适用于所有满足测试条件的元素出现)。  list.remove_if(test_condition);  面前()  返回列表的第一个元素  list.front();  背部()  返回列表的最后一个元素  list.back();  push_front()  在列表的开头(开头)插入元素  list.push_front(element);  推回()  将元素插入列表的后部(末端)  list.push_back(element);  pop_front()  从列表的开头(开头)删除元素  list.pop_front();  pop_back()  从列表的后部(末端)删除元素  list.pop_back();  插()  将元素插入指定的索引/位置  list.insert(iterator_position，element);  要么  list.insert(iterator_positon，number_of_elements，元素);  begin()和end()  返回指向列表的第一个和最后一个元素的迭代器  list.begin(); 和list.end();  rbegin()和rend()  返回指向列表的第一个和最后一个元素的迭代器(以相反的顺序)，即第一个元素将被视为last，最后一个将被视为first  list.rbegin(); 和list.rend();  分配()  分配新元素集或将当前元素替换为新元素集  list.assign(n，元素)  //将“ element”，“ n”次分配给列表  合并()  它合并两个列表。  list1.merge(list2);  独特()  它从列表中删除连续的元素。  list.unique();  擦除()  它从给定范围(index1，index2)中删除指定的索引或索引，可以通过使用迭代器定义位置来使用此功能。  list.erase(iterator_position);  要么  list.erase(iterator_position1，iterator_position2);
