Cf -- carry flag ). If cf = 1, carry or borrow digits are generated during arithmetic operations. Otherwise, cf = 0. The shift instruction affects cf. PF -- parity flag (parity flag ). If pF = 1, the number of "1" in the operation result is an even number. Otherwise, pF = 0. This flag is mainly used to check errors du

Onnewintent method is called.SingletaskThere is only one instance. If you launch it in the same application, if the activity does not exist, a new instance is created in the current task and, if present, the other activity on top of the task is destory off and the Onnewintent method is called. If you start it in another application, a new task is created and the activity is started in that task. Singletask allows other activity to be stored in a task, that is, if I open a new activity in this S

After a long period of development in Linux, many users have become very popular with Linux. Here I will share my personal understanding that there are many problems with the sound card driver, in many cases, if there is no sound, the Intel integrated video card may crash when setting the resolution in graphics mode, and the integrated media playing software may not run stably. Hongqi Linux7.0 Olympic Preview Details :.Of course, this version, as a product in the testing phase of the red-

combined enumeration constant do not overlap. Consider creating an enumeration constant for common flag combinations. For example, if an enumeration for file I/O operations contains enumerated constants Read = 1 and write = 2, consider creating enumeration constants ReadWrite = Read OR Write, which combines the Re Ad and Write flags. In addition, in some cases, a bitwise OR operation for a composite flag
