ensure that memory operations do not cause page faults, provide consistent, predictable program behavior, and thus provide performance. Safety (Security) If the memory contains a private secret, the secret may eventually be stored in unencrypted form on the hard drive by the page schedule. For example, if a user's private key is normally stored on disk in an encrypted manner, a key backup in memory for encryption is finally saved in the swap file. In a highly

Characters in the file name is not guaranteed. Code 1: #include Library. h and Library. h may indicate the same file. It is unclear whether utilities_math and utilities_physics can be distinguished. Solution: #includeDo not replace security functions with insecure Functions Macros are often used to fix existing code and replace another identifier globally with one identifier. However, this method has some risks. When a function is replaced by a function that is not

Based on the engineering practices of this project, it summarizes the methods and tools for using the C ++ language mechanism, development environment, and Related Quality Assurance tools to prevent and discover various defects related to compilation, runtime,

Naming rules are important for easily maintainable code. Objective-c's method names are often very long, but blocks of code read like prose, and do not require too much code comments.When writing pure Objective-c code, we basically adhere to the standard objective-c naming rules, which may be quite different from the C + + style guide. For example, Google's

C language based on Hoffmann Coding ?1. Hoffman encoding descriptionThe Harman tree, which is the optimal binary tree with the minimum length of the weight path, is often used for data compression. In computer information processing, the "Harman encoding" is a consistent encoding method (also known as the "entropy encoding method") for data lossless compression. This term refers to the use of a special enco

Good programming standards will effectively help developers avoid developing potentially dangerous code. In general, to reduce memory defects, the following

The current interval of the 1st encoding symbols is its initial encoding interval, and the current interval of the I encoding symbol is [low, high) after the I-1 ), the current interval algorithm for the I + 1 encoding symbol is as follows: high = low + D * the upper limit corresponding to the I + 1 Initial encoding symbol, low = low + D * lower limit corresponding to the I + 1 encoding symbol, and then the p

C ++ uses two basic parameters for arithmetic coding: the probability of a symbol and Its Encoding interval. The probability of a source symbol determines the compression encoding efficiency and the interval of the source symbol in the coding process, the encoding interval determines the output after the compressed symbol.
