(4) parse the C statement Before continuing to explore the C pointer, it is necessary to parse the complex declaration syntax in the C language. You only need to remember two points: one principle and one rule. Principle: first look at the

Chapter 4 pre-processor I skipped the advanced pointer topic chapter. Too many tips and too many academic discussions are not suitable for me now. But I did read it, and I didn't understand it in many places. If anyone reads it, they can talk

In the project, when we need to upload the data file to FTP, in order to ensure data integrity, we will calculate the MD5 of the data file and upload the MD5 file together with the data file. So how to generate the MD5 of the data file? We can use

The named parameter (named arguments) means that you can call the parameter by specifying the parameter name when calling the function. The biggest advantage of this function is to facilitate the ordering of parameters according to the caller's

Frontier: The extension method enables you to "add" methods to an existing type without creating a new derived type, re-compiling, or modifying the original type in other ways. An extension method is a special static method, but it can be called

I have also checked the three-layer concept and read it. Below is a simple example of the three-layer architecture. Let's take a look at how it is implemented.Let's take a look at the Entity class-model essence: the entity class is to complete the

(6) Use of const Const in C expresses the meaning of "constant", which is more accurate to the meaning of "read-only. When a const encounters a pointer, it produces different results due to its different relative positions. Example (1) The const is

Directory Delegate Action Func SummaryDelegate Delegated tasks The basic definition of delegation is briefly introduced in this article a long time ago. Let's take a look back. The delegate is type-safe in C #. You can subscribe to one or more

A considerable portion of the current web pages use Ajax technology. Neither WebClient nor httprequest in C # can produce correct results, because these scripts are executed only after the server has sent them!However, it is normal to use IE to

Question: Find the prefix that can match strings   For this question, you only need to keep asking for next until next is 0. Remember that the answer is the total length minus the next length.     1 #include 2 #include 3 #include 4 using

In C/C ++, how are floating point numbers, float, and double stored in the memory? Assume that I have 32-bit8bit 8bit 8bit 0 0 0 0 1 1 1 1 For integer int, we can quickly conclude that this is the memory format of int I = 15.Assume that the bitwise

During development, a method in one module is often used to call related methods in other modules. For example, if an error occurs in a system, you can call a method in the module for error handling. Because there are many error handling operations,

// Function meaning: Split the complex logic in the main function. There is a separate function to process a separate module. The main function only plays a macro-control role./*Function Definition: includes the following four parts:1. Return Value

Single-source shortest path problem Bellman-Ford code (c) Address: http://blog.csdn.net/caroline_wendy Single-Source Shortest Path: fix a starting point and find the shortest path to all other points. Bellman-Ford: Set the shortest length from

C ++ primer Reading Notes 11-PolymorphismPolymorphism is also an important aspect in C ++. polymorphism and dynamic type. virtual functions are essentially the same thing.1. Virtual FunctionsAdding the virtual surface before the member function

HDU4850 is used to construct a string with a length of n. It is required that any substring with a length of 4 be different. N "= 50 W. (26 letters are used) Constructor: 26 strings. A maximum of 26 ^ 4 different strings can be constructed. The
