Article 01: Treat C + + as a language federalC + + = C (c basic syntax) + object-oriented C + + (class, encapsulation, inheritance, polymorphism ...) + Template C + + (Generic programming) + STL (container, iterator, algorithm, function

Arrays consist of a series of identical elements const int Days "10" = {31, 23, 45, 56, 78,}; the array defined with the const declaration is an array constant, after which it is read-only and cannot be changed in the future, except that it can

1. The case with pointers--class with pointer member (s) in a class often occurs, typically: the String class.2. The string class in STL is too complex, copy on write, and so on.3. Use "Defensive header file declaration".4. S2 assignment to

Today in Bo asked to see a friend's problem, roughly in the network program, printed out of the 16 number, inexplicable appearance ffffff. For example, a byte is really worth 0xc9, and printing out is 0xffffffc9. The original Bo asked the connection

String is currently processing is currently the most problems in the project, especially natural language processing, text processing and analysis, and so on, C + + currently only provides a relatively simple string processing function, unlike

1. There are three types of transformation grammar,C-style Transformation: (T) expressionFunction Style Transformation: T (expression)There are no differences between the two ways, except for the position of parentheses, which can be referred to as "

Summary: C + + is a programming language developed on the basis of C language, which integrates object-oriented programming, generic programming and procedural programming. Widely used, it is a kind of static data type checking, and supports

Practice 1-6 Verify that the value of the expression GetChar ()! = EOF is 0 or 1.The code is as follows:#include //contains information about the standard library. intMain ()//defines a function named Main, which does not accept parameter values. {

>1.c++ 's protection model comes from the concept of access permission and transfer;The distinction between initialization and assignment comes from thinking of transfer ability;The const concept of C + + is evolved from the read-write protection

For classes and class inheritance, there are several main issues:1) Inheritance mode: Public/protected/private inheritance.This is a C + +, in fact, inheritance is a kind of permission to allow sub-class control ideas. The subclass inherits from

C + + library functionsC + + standard cubby C standard library to be a lot more complex, we need to study hard. C + + Standard library has been set up late, which solves some problems of C standard library. Through careful study, proficiency will

. NET programming is one of the most frequently used elements. In either ASP. NET or Winfrom development, form load (load), Draw (paint), Initialize (init), etc."protected void Page_Load (object sender, EventArgs e)" This code believes that no one

1. Concurrency: Do multiple things at the same time.2. Multithreading: A form of concurrency that takes multiple threads to execute a program. Multithreading is a form of concurrency, but not the only form.3. The thread pool holds the queue for the

Some programs run, may call external DLLs, users may accidentally lose these DLLs, causing the program to not function properly, so you can consider embedding these DLLs into the resources, automatically released at startup. For managed DLLs, we can

The basic process is the same whether you call Win32.dll or Mfc.dllThe following is an example of a Mfcdll project called VC + + written by Callmfcdll C # project1, add in the MFCDLL.hextern "C" __declspec (dllexport) int add (int x,int y);//Export

First, the declared accessibility in C #1. Public: access is not restricted;2. Internal: Access is limited to the owning assembly;3. Protected: Access is limited to the current class and its subclasses;4. Internal protected: Access is restricted to

C advocates the use of variable names of a certain meaning. There are several simple C naming conventions that you must follow:© only alphabetic characters, math and underscores (_) can be used in names© the first character of a name cannot be a
