Recently, April 15, the Malwarebytes forum began to appear on the issue of malware detection. It seems that suddenly it treats some parts of the OS file and itself as malware.

(4) No semicolon at the end of the macro definition;5The macro definition is written outside the curly braces of the function, and the scope is followed by the program, usually at the very beginning of the file.

Detailed analysis of JavaScript function definitions and javascript function definitions
Function
Key points:
A). functions are first-class citizens (importance) in javascript)B). A function is an object.C). The function defines an independent variable scope.
Definition Method
A) Name function:
Unless defined in another function, the name function is global.
// Global name function add (x, y) {return x + y;
In the other use of inline in the previous article, it is mentioned that the function implementation differs from the class definition in the class definition.Now let's look at an experiment:A.cpp:[CPP]View PlainCopy

#define Test_h
Class a{
Public :
int Fun (int x) {
return (x*x+1000);
}

Differences between JS function definitions and js function definitions
There are two methods to define JS functions:
(1) typical function declaration
Function slide (arguments) {//... code}
(2) define a function in the form of a function expression
Var slide = function (arguments) {//... code}
Although the above two methods are logically equivalent, they are slightly different:Difference 1: Functions

In C language programming, for a relatively large project, the use of the library will be more, if the design of a slight negligence, it may create a macro-defined conflict. An example of a project is that the two header file defines "isspace (CH)", and the two macro definitions are inconsistent, causing the entire project to fail to compile.
The solution to this problem is to undefine the macro by undefine the conflicting macros immediately after th

In order to allow the program to be split into several logical parts, the C + + language supports a separate compilation mechanism, allowing the program to be split into several files, each of which can be compiled independently.To support split compilation, C + + separates declarations and definitions. A declaration makes a name known to the program, and a file must contain a declaration of that name if it wants to use a name defined elsewhere. The d
