There are three kinds of preprocessing functions in C: 1. File contains # include 2. Macro Definition # # 3. Conditional Compilation # if #ifdef等.preprocessing is pre-processing by the preprocessor prior to being compiled by the compiler. The

I. Common function pointersLet's first look at one of the simplest functions:void fool (int a) { Endl;}Then its function pointer type is:void (*) (int)We can test it this way:void (*pfunc) (int) = &foo; // here PFunc is a pointer pFunc

Think of themselves every day sort of sort, bubbling ah, binary search Ah, the results in the STL with the sorting function Sort,qsort, finally freed himself ~So I summed up a bit, first look at the sort function in the following table:

C++orm framework automatically generates code databaseUsed Java know SSH framework, especially for database development, Java domain has countless ORM framework, for data persistence layer call, such as Hibernate,ibatis (now renamed MyBatis),

7. Pre-prepared for insufficient memory.New when unable to complete the memory allocation request, will throw an exception, what to do, this is a very realistic and definitely to meet the problem.In C, macros are generally used to allocate memory

The general book always uses int to give an example, that is too simple. What if the static variable itself can be an instance object? It should be possible, but this involves its constructor and how its internal static variables initialize two

This article link:http://www.cnblogs.com/xxNote/p/4009359.htmlReading today when you see the free function to release the memory of the dynamic application only need to pass the first address of the memory block, it is clear that only the first

First, the header file Protection of #defineThe header file Foo/src/bar/baz.h in Project Foo is protected as follows:#ifndef Foo_bar_baz_h_ #define Foo_bar_baz_h_ ... #endif // Foo_bar_baz_h_#define #else #define #endif#define #else #define

#include //preprocessor compiler directive int main ()//function Header: Summarize the interface between the function and other parts of the program int: The return type of the function {using namespace std;// Introduce namespaces stdcout

This is a very classic face test, can be a short time to examine the students of C + + mastery is comprehensive, the answer to include the most knowledge of C + + class, to ensure that the writing of the string class can be assigned, copy, define

Recently a classmate asked me how to use the ListView to load a picture list, in the "C # System App" in front of the Treeview+listview+contextmenustrip Control Implementation tree view of the disk directory, and displays the details of the file in

The syntax analyzer of this version is generated by the tool YACC and its source file is Lua. Stx. This is not my focus. I skipped it.The end of this section is a bit cool, just a few words.The history of YACC is not mentioned. The emergence of YACC

46. to release resources, you must implement the idisposable interface. It is best to implement it in the dispose mode recommended by Microsoft. After the idisposable interface is implemented, the garbage will be automatically cleared in the using

如果你不希望一个类被继承，那么可以把这个类声明为sealed类。 除此之外，声明为sealed类还会带来如下好处 1. 提高函数调用效率 JIT（Just in Time）编译器会优化sealed类的函数调用。 比如，如果从一个sealed class的实例上调用一个virtual method，那么就会把这次调用变成是non-virtual.   2. 更好的type safe保证 interface IInterface{}class MyClass{}class

Recently I reviewed the source code of ffplay. Ffplay is an example of a player provided by the FFMPEG project. Although ffplay is just a simple player example, it has a lot of source code. The code is mainly focused on a "point" for research, but
