mcafee definitions

First, the key:1,Inline functions are the same in readability as functions, while at compile time the functions are embedded directly into the body of the caller, eliminating the call/return instruction, which is faster at run time. 2,Inline functions can be debugged, and macro definitions cannot be debugged. Inline functions and macros are essentially two different concepts if a program writer has a requirement for both fast and readable conditions

Add a module definition After completing the work described in the previous articles, we can add the module to the DNN. Although the module can not be run now, but first added to the side of the development side to see the effect of it. First, use host (host Administrator) identity login, into the "host--> module Definitions", click "Add new Module definition" To add the newly defined module. Second, enter the following module information and then

NSArrayand NSMutableArray --arrays are ordered sets of multiple objects. Accesses an object by specifying its location (that is, the index) in the array. The index of the first element in the array is 0 (0). NSDictionaryand NSMutableDictionary --the dictionary stores its entries as key-value pairs; The key is a unique identifier, usually a string, and the value is the object you want to store. You can access the object by specifying the key. NSSetand NSMutableSet --the collection stores a

What is a function?A function is a method or a program that can implement certain functions, and a simple understanding of the concept of a function is that you write statements that, for ease of use, combine these statements to give it a name, the function name. When you use this name, you can implement the function in the statement group.Some of the functions in Python are called built-in functions and do not need to be written by ourselves. There is also a third-party function, is the other p

10.1.5 Refactoring Members　　There is a handy technique for adding properties, you can generate properties from fields there is a handy technique for adding properties, you can generate a genus from a field, and here is an example of refactoring (refactoring), which means modifying the code using tools rather than manually modifying it . To do this, just right-click a member in the class diagram, or right-click a member in Code view.For example, if the MyClass class contains the following fields:
