Search, is a C + + technique, today, to give you a talk. First, what is search? Just like searching for something on Baidu, searching for something. First, let's take a look at general search:---------------------------------------------------- The

Principle: Compare the adjacent two elements, as long as they do not conform to the order of the exchange;Important: 1. Do not cross the border; 2. The largest element will go to the end after the traversal, so the next traversal does not have to

The C + + modifier types are as follows:Signed, unsigned, long, shortC + + Type qualifier:Const: The variable cannot be changed during program executionVoltile: This modifier tells the compiler to not need to optimize voltile declared variables, so

First, what is an exceptionPredictable but unavoidable mistakes.Second, how to throw an exceptionThrow data:A, you can throw a primitive type of exceptionThrow-1;Throw "I'm abnormal"B, can throw exception of class typeThrow Student Stu;Note: Do not

Value Callis the default parameter passing mechanism, which is copied to the formal parameter, the semantics of the call is that each time a copy of the argument is obtained and the replica is used as a formal parameter, there is the cost of the

Regular expressions extract valid information for a large number of strings, supported header file # include

The so-called template function is actually to establish a general function , the general function of the formal parameter type is not specified, with a virtual type to represent, this general function is called the function template .Cases:#include

C # comes with the System.IO.Compression namespace compression class implementation of the multi-file compression and decompression function, the drawback is that the decompression of multiple files can only call their own decompression method, and

Static class:Adding a static decoration to the class (classes) indicates that the class cannot be instantiated, and that a variable or function cannot be instantiated in that class.Then if you want to add functions, variables, and properties to this

Extension methods can "add" methods to existing types without having to create new derived types, recompile, or otherwise modify the original type. The extension method must be a static method and can be invoked just like an instance method. A

A mailbox is an important part of the actor model that is responsible for receiving and receiving messages, and saving them for actor processing. Two kinds of queues are maintained in the mailbox, one is the system message, the other is the user

C # Delegate1. Delegate definition: The delegate is a data type, and the class is the same level, delegate can directly look at the keyword class, we can directly see the delegate as class, the difference is that class is stored in a series of
