3.6 Accessing elementsIf the container is not empty, then the front and back members of the container type will return a reference to the first or last element within the container.

(3) Container Adapter)In addition to the basic container class, the C ++ standard library also provides some container adapter classes to meet some special requirements. These container adapter classes are implemented by the Basic

The priority queue allows the user to push any elemen
In the c ++ standard template library, there are three types of containers: sequential containers, associated containers, and container adapters. An ordered container is a linear ordered cluster. The underlying implementation relies on linked lists or arrays. An associated container is a non-linear tree structure that
subscript indicates that [] can only extract existing elements (that is, it can be understood that cross-border access is not allowed in the array), especially when a vector object is just defined, the number of elements of the default object is 0, and an error occurs during subscript access.
C ++ProgramAll members use the iterator as a tool to access the container.

the priority queue Assistant. The priority queue allows the user to push any element into the container in any order, but it must be taken from the element with the highest precedence at the time of removal. According to the arrangement of the elements, the heap can be divided into max-heap and Min-heap two, the former each node key value (key) is greater than or equal to its child node key value, the latter of each node key value (key) is less than
statement:1, Ben Boven mainly from the "C + + Primer" and "STL Source analysis" These two classic books. At the same time, also referred to the network of many excellent blogs, the authors of these blogs thanked. 2, due to the limited ability of bloggers, the use of some containers may not have been in-depth study. Therefore, if there are errors and deficiencies in this blog, you are welcome to criticize. 3, Ben Boven only for academic exchanges only
Refer to C + + primer.Vectors are a collection of objects of the same type, each with a corresponding integer index value. As with string objects, the standard library is responsible for managing the associated memory of the storage element. We refer to the vector as a container because it can contain other objects. All objects in a container must be of the same
1. Container element typeMost data types in C + + can be the element type of a container. The container element type must satisfy two conditions: assignment and copy operations are supported.So no element is a container of the reference type, and neither the Io object nor th
elements, if return 0 indicates the element to be deleted. C.erase (P) in the container removes the element specified by the iterator p from c. P must point to the true element in C and cannot be equal to C.end (). Returns an iterator to the element after P, and if p points to the tail element in C, returns C.end () C

OverviewVector is part of the C + + Standard Template Library, which is a multifunctional template class and function library that can manipulate a variety of data structures and algorithms. A vector is a container that can hold various types of objects, in short, a vector i
in the container without knowing how it is implemented internally. It behaves much like a pointer, and can be used to access the specified element. But the two are quite different things, the pointer represents the memory address of the element, that is, where the object is stored in memory, and the iterator represents the relative position of the element in the container.
To customize an iterator, you ove
The so-called container, is a box of things, in C + +, we put things called "element"and sequential containers, which means that these things are in order, what order you put in, what order they are inside.There are several sequential containers in C + +:
Vector
Variable size array
Deque
Dual-ended queues

Placing elements in a double-ended queue containerThere are several ways to put elements into a double-ended queue container: constructors, P
The container type of C + + can be divided into two categories: sequential container and associative container. The knowledge of sequential containers can be reviewed in my previous essay, "C + + sequential container knowledge sum
Containers in C + + can be roughly divided into two broad categories: sequential containers and associated containers. The sequential container contains a sequential container adapter.
Sequential containers: Aggregates elements of a single type into containers and then stores and accesses them based on location. The main vector, list, deque (two-terminal queue).
