unsigned Long value that is the same as the Bitset object's bit-mode store value. You can use the To_ulong operation only if the length of the Bitset type is less than or equal to the length of unsigned long : unsigned long ulong = Bitvec3.to_ulong ();cout The To_ulong operation is mainly used to move the Bitset object to a C-style or standard C+ + style before the program. If the Bitset object contains more bits than the length of the unsigned long, a run-time exception is generated. Th

about MapThe map type container is a collection of (key key-value) pairs. Map containers are generally understood as associative arrays and can be used as subscripts to get corresponding values, similar to built-in array types. The essence of an association is that the value of an element is associated with a particular key, not by its position in the array.In summary, map is a sort structure of many pairs of key values, and the key values are unique .Multimap-type containers and map-type contai

end does not move. but Deuqe, after all, cannot be directly a stack, and it does not directly meet your requirements , because you cannot prevent others from moving your things on the other end of the way. You need to wrap it up and make some restrictions so that it can only be inserted and deleted at one end. That means you have to provide a "socket", the "socket" on the deque, the other end in your program, you can use the stack structure. And the stack is the "socket" that connects the Deque

The STL find_if algorithm is used to find the eligible elements within the containerExamples are as follows: 1.

C + + STL container deque is similar to vector, and also uses a dynamic array to manage elements. You need to include the header file before using deque: #include It is a class template defined within a namespace std: TemplateClass _ax = allocatorClass Deque; The first template parameter is used to represent the element type, and the second is optional, specifying the memory model. The default memory model is generally used. Unlike vectors, the dyn

STL Map Common Operation Introduction 2008-09-18 13:38 1. Introduction to Directory map features use map to insert elements in a map to find and get elements from a map to remove elements from a map2. Map IntroductionMap is a kind of associative container. It is characterized by the addition and deletion of the node to the iterator is very small, in addition to that Operation node, the other nodes have no effect. For iterators, you can mod

Problem, implement the next_permutation () in STL . Answer from StackOverflow: Let's look at some of the permutations first: 1 of 2 3 4 1 2 4 3 1 3 2 4 1 3 4 2 1 4 2 3 1 4 3 2 2 1 3 4 ... How do we move from one arrangement to the next? First of all, let's look at the problem in a different light. If each element of the arrangement is treated as a number (which is, of course, a number, but the element is "a" and "B"), each arrangement is treated as a

The basic containers in STL are: string, vector, list, deque, set, map Both set and map are unordered save elements that can only be accessed through the interfaces it provides Set: A collection that is used to determine whether an element is in a group, using lessMap: Mapping, equivalent to a dictionary, mapping a value to another value, if you want to create a dictionary use it well string, vector, list, deque, set are ordered containers1.string A s
