As a result, we are wasting time by tracking code.should be replaced with constants:1 Con

I 've been away from C/C ++ for a long time. I just saw that I found that the basic skills I 've learned are not clear about # define and typedef ...... Shame !! 1) # define is a pre-processing command. It is a simple replacement during compilation and pre-processing, and does not check the correctness. It does not mean that it is correct or not, possible errors are detected and reported only when the expa

Briefly summarize the differences between two constants in PHP that define keywords:1, define is a function, const is the language structure, PHP compile-time const fast.2, define can only be used outside the class, Const class within the class can be.3. Constants defined by define are global, and const-defined constan

Asynchronous modules define AMD and asynchronous modules amd It is called Asynchronous Module Definition, and is defined by Asynchronous components (or modules. AMD is a mechanism in which components and their dependencies can be asynchronously loaded.Define Method define(id?, dependencies?, factory); Component ID The component ID is the unique identifier of a component. In a script file that is one-to-one

I. Usage of typedef In C/C ++, typedef is often used to define an alias for an identifier and a keyword. It is part of the language compilation process, but it does not actually allocate memory space, such: Typedef int;Typedef int array [10];Typedef (int *) pint; Typedef can be enhancedProgramBut it also has some disadvantages such as "non-intuitive. Ii. # define usage #

Difference between typedef and # define 1. typedef Typedef is the meaning of the type definition, but itInstead of defining a new type, you can create an alias for an existing type., Similar to the meaning of the reference,References are aliases of variables or objects, while typedef defines aliases of types.. Typedef has two main functions: 1.1 simplify complex type declarations Simplify complex type declarations, or give existing types an alias

According to the manual, the constants defined by define are only allowed:Only scalar and null are allowed. The scalar type is integer, float, string, or boolean. It can also define the type of constant value as resource, but it is not recommended to do so, it may cause unknown conditions.Today, I read the php source code and found that the second parameter of define
