ioc container c#

The list container corresponds to a list of common data structures. The list container supports fast random inserts, deletes, but does not support fast random access elements; This is not the same as the vector container, vector containers do not support fast random inserts, deletes, but support fast with Machine Access element. The properties of the list

C + + linear sequence container The vector is a variable-length array, which is used without the need to declare the upper bound, and as the element increases, the length of the vector increases automatically; the vector class provides an extra way to add and remove elements, which is more efficient than array operations.Header files: #include Namespaces: Using Namespace Std:vectorconstructor functionvector

using Emplace_back in-place constructionEmplace_back can be in- situ through the parameters of the construction of objects, do not need to copy or move memory, compared to push_back can better avoid the memory copy and move, so that the performance of the container insert element is further improved. in most cases, emplace_back should be preferred instead of push_back. All of the standard storage (except for the array, since it is immutable and cannot

The definition of the queue template class is in the The queue is very similar to the stack template, and the queue template also needs to define two template parameters, one element type, one container type, the element type is necessary, the container type is optional, and the default is the Dqueue type.The sample code that define

RIT M.rend () Returns the address of the first element of the forward direction, which is the reverse address of the end. int M.size () Returns the number of elements already present in the map.

STL Source First ContactSTL = Standard Template Library, the literal translation comes from: Standards templates, is the HP Lab developed a series of software collectively. Fundamentally, STL is a collection of "containers" that have list,vector,set,map and so on, and STL is also a collection of algorithms and other components. The collection of "containers" and algorithms here refers to many of the world's most intelligent people for many years. The purpose of STL is to standardize the componen

Common capabilities of STL containers All containers provide "value semantics" rather than "reference semantics". When an element is placed in a container, the internal copy or move, rather than the reference of the management element. Elements have their specific order within the container. In general, each operation is not completely secure, and the caller needs to ensure that the argumen

Vector Vectors are collections of objects of the same type. Each object in the collection has a corresponding index. Vectors are often referred to as containers (container).To use vectors, you need to: #include The vector is a class template (classes template). C + + has functional templates and class templates. The template itself is not a function or class, it must be instantiated by the co

The C ++ STL container deque is similar to the vector and uses dynamic arrays to manage elements. Before using deque, you must include the header file: # Include It is a class template defined in the namespace STD: Template Class _ AX = Allocator Class deque; The first template parameter is used to indicate the element type. The second parameter is optional and specifies the memory model. The default mem
