scratch coding

C ++ starts from scratch (5) -- What is a pointer? (This article is the first time to write and has incomplete thinking, which may lead to conceptual confusion and is not recommended for reading. For more information, see pointer and its semantics and application.) This article describes the key to the duplication in C ++-pointer type and two meaningful concepts-static and dynamic. Array As mentioned above, the memory is accessed through variables

From Macroscopic to microscopic understanding of coding, macroscopic and microscopic coding Macro thinking is to have a clear understanding of what we do and understand what we are pursuing. After understanding the whole, we need to have a deep understanding of what we are interested in. This is the so-called micro-thinking. The old saying "not seeking the whole, not seeking a domain" is the same. I persona

Some jQuery coding skills and jQuery coding skills Cache variableDOM traversal is expensive, so we try to cache elements that will be reused. // Bad h = fill ('height', h-20); // recommended $ element =$ ('# element'); h = element.height();$element.css ('height', h-20 ); Avoid global variablesJQuery is the same as javascript. In general, it is best to ensure that your variables are within the function scope

C # Coding Standard-coding habits 1. Avoid placing multiple classes in one file. 2. A file should have only one namespace. Avoid placing multiple namespaces in the same file. 3. A file should not exceed 500 rowsCode(Excluding the code generated by the machine ). 4. The code length of a method should not exceed 25 lines. 5. Avoid more than five parameters in the method.

in "C ++ from scratch (2)", to check the ASCII code corresponding to a character, you must add single quotation marks on both sides of the character, for example, 'A' is equivalent to 65. To indicate multiple characters, use double quotation marks, for example, "ABC ". To record characters, you need to record the corresponding ASCII code, and the ASCII code value is within-128 to 127. Therefore, you can use a char variable to record an ascii code, in

Reprinted please indicate the source: http://blog.csdn.net/horkychen (Excerpt from msdn-coding techniques and programming practices) Names) Naming is most helpful for understanding the logical structure of a program. A name description is "what" is more important than "how. Naming can avoid exposing the underlying implementation, thus retaining an abstract layer, simplifying the complexity of the program. For example, you can use getnextstudent () in

Manchester Encoding(Manchester Encoding), also known as Phase Encoding (PE), is commonly used for LAN transmission. In Manchester Coding, there is a hop in the middle of each bit. The hop in the middle is both a clock signal and a data signal. However, in different books, in Manchester encoding, the value of the level beat expression is different, which produces many ambiguities: 1. Network Engineer ExaminationAnd related materials: Bit CenterThe
