1, init is the system boot up after the first running process, is the system's most important daemon, the process number is always 1.2. With the boot of the machine, Init starts at run Level 0 and runs from the first level to the default run level set in/etc/inittab. When the machine shuts down, the same process is performed in reverse order.3. The main file of the startup script is located under/ETC/INIT.D This directory, each script is responsible for a daemon or a specific aspect of the syste

Event A occurs when the code that handles event A is executed. However, determining when an event A and when to execute the code is fixed, can be written first, and event A's specific implementation code is open to other developers to write. There can be many different implementations that can be registered with the specific implementation to be processed.

Instanceof is used to check whether the object pointed to by the reference
, using the curly braces that are reserved for the dictionary. Set ([1,2,3,4]) and {1,2,3,4} are equivalent in Python3.0. Regardless of how the collection is created, Python3.0 uses the new constant format to display it. In Python3.0, the built-in set function is still required to create an empty collection or to build a collection from an existing iteration object, but the new constants facilitate the initialization of a collection with a known structure.Set set is a powerful and flexible objec
letters in the class name are capitalized, so that the package name and the class name can be distinguished clearly when referencing.
by statically introducing a package, you can directly reference a static member method or static member variable of a class. For example, an import static Java.lang.Math.PI uses the import statics of the class to be used in the passive resource, then the PI instead of the Math.PI can be used directly in the next code. In addition, you can represent all static

inverse code operator ~ logical non-operator! The sizeof operator sizeof operator computes the number of bytes required to store an object of the same type as its operand, either as an evaluated expression or as a type with parentheses, and when sizeof is used for char, the result is 1 for the array. When the total number of bytes in an array is used for structs and unions, the result is that the number of bytes of the object includes any padding space required by the array contained in the obj
