PDB is the abbreviation of program Debug Database;BackgroundI'm in charge of a services (service) problem, because of a DLL internal logic problems;After modifying the source code locally, rebuild the DLL (debug mode), then replace the DLL in the

1. Compiling, linking and running the programC code example:#include #include int main(){ printf("hello world！\n"); exit(0);}The compile run parameters are as follows:[[email protected] Desktop]# gcc -o hello hello.c[[email protected] Desktop]#

1. Knowledge pointsThree-Step walk: Application, release, pointer empty.1.1malloc, free functionIn the C language, the memory malloc function requests dynamic space, and the following shows its basic usage:1 int *p = NULL; 2 p = (int *)malloc(sizeof(

this is Bwar in 2009 to write the design pattern C + + implementation, code can be compiled to run, has been existing in their own computer, has been sharing in the team technology sharing, is now moving to the line. 1. Template Method Brief1.1

Conditions (look at each of the basic types for a few bytes first):voidSize_ () {printf ("char type:%d\n",sizeof(Char)); printf ("int type:%d\n",sizeof(int)); printf ("Float type:%d\n",sizeof(float)); printf ("Double type:%d\n",sizeof(Double));

To address the problem of C + + memory leaks, C++11 introduced smart pointers (smart Pointer).The principle of smart pointers is to accept a well-applied memory address, construct a smart pointer object stored on the stack, there is an important

Standard conversionsThe C + + language defines conversions between its underlying types. It also defines pointers, references, and conversions to pointer-derived types of members. These conversions are called "standard conversions."1. Integral type

The function template Men_fn () is equivalent to the built-in functor in STL, converting member functions to function objects and binding using object pointers.Usage is similar to bind in c++11.Template classclass t> /** /MEM_FN (Ret T::* pm);The

ObjectiveThe recent period of time to look at the code, the use of C + + smart pointers, found that they can not understand the code in the expression of what meaning, so dedicated to take a time to make up their own this lack of knowledge.Reference

View C + + as a language federation--"effective C + +"OOP is an important part of C + + and is more and more complex. Summarize the structure of knowledge that exists in my mind1. Access specifierI. Intra-classPublic: The most open permission, which

Friend functionThe private properties of a default class can only be accessed directly within the class.友元函数申明在内的内部，实现在类的外部可以直接访问类的私有属性。classa1{ Public: A1 () {a1 = -; A2 = $; }intGetA1 () {return This->a1; }//Declare a friend function friend

In the study of C + +, when we conduct object-oriented analysis, we will find someAbstractThe concept. So how are they described in object-oriented languages? How is the area of the specific shape calculated? Graphs can be divided into rectangles,

Reverse iterator• A reverse iterator is an iterator that moves backwards from the tail element to the first element in the container. For reverse iterators, the meaning of the increment (and decrement) operation is reversed.• Incrementing a reverse

1, short-circuit operation # include void main1 (void){Short-circuit operation, logic and operator, if left operand is false, right operation number is shortedint a = 5;if ((4 if ((4 > 3) && (A = 2))printf ("11111111111\n");Elseprintf

Examples of inheritance of classes:As an example of the production of the above dynamic Milky Way galaxy, suppose we define a class of stars as follows:classStar{ Public: Star () {}~Star () {} voidInit (); voidMove (); protected:

public static void Readjson (){String jsonfile = "D://tsconfig1.json";using (System.IO.StreamReader file = System.IO.File.OpenText (jsonfile)){using (JsonTextReader reader = new JsonTextReader (file)){Jobject o = (jobject) jtoken.readfrom

? One of the reasons for generics is to solve the boxing and unpacking problems of elements in the original collection class:First, the generic type: /// ///return to foreground message/// /// Public classYzt_message {

Today when reading the Code book, useful to Try--catch--finally, and then checked the specific attention and application.In simple terms:try {There may be code or code snippets that are wrong}catch{If the code in the try is wrong, an error is
