actually calling IndexOf, contains, and so on, is a simple loop to perform to find the element. So frequent calls to such methods are not faster than you write the loop on your own and slightly optimized, and if this is the case, it is recommended to use a set of key-value pairs such as Hashtable or SortedList.ArrayList al=new ArrayList ();Al.

contains the interrupt mask register and we willrefer to this as the Mask register . Choose the appropriate address Dependingupon which interrupt and controller to use. The Interrupt mask register is a eight bit register that lets your individuallyenable and disable interrupts from devices On the system. This is Similarto the "CLI" and STI instructions,but on a device by device basis. Writing a zero to the corresponding bitenables that device ' s interrupts. Writing a one disables interrupts

The array function is indeed very powerful and useful, but now another problem is that all employees of the company should be managed and the information should be added when new employees join, when someone leaves, the information will be deleted. That is to say, this is a dynamic management process. If an array is used, it is not known how much space should be opened for the array. If it is large, it will be a waste, but it will not be enough in the future, as a result, the dynamic features of

intuitive explanation can be as follows: 8421bcd is used to represent 0-9, and the six numbers 1010, 1011, 1100, 1101, 1110 are not used. In decimal operation Once these six numbers are displayed, they are incorrect and need to be adjusted. 4. What is the difference between the secondary carry mark AF and the lower four digits of Al?

: The file owner, the same group of users, and other users. The owner is typically the creator of the file. The owner can allow the same group of users access to the file, as well as the access rights of the file to other users on the system.　　In this case, every user in the system can access the files or directories that the user owns. Each file or directory has three groups of access rights, each group is represented by three bits, respectively, the read, write, and execute permissions of the

another list. You can also use the repeating operator to recognize the operator as a multiplication operator so that you can build a larger list from a small fragment. The previous example shows you how to add elements to the list and how to modify the entries in the list. The previous example also shows how to remove an object from the list. The first way to delete an entry is to use the Del method. Use this method to delete an entry or a range of entries. You can also use a flexible and powe

concentrate. Of course, some programs may not be condensed because of the amount of work and the details of the processing. 2, in a similar program, to find different instructions or processes, and if not, that is repeated, it is desirable to merge. 3, replace the different instructions or processes with variables, or put the entry of the various programs in the register. 4, the program in the application of the process, set the variables and the use of registers. 5, merging similar program
