Introduction Memory management has undergone several changes, but it has not yet matured. These changes mainly include: 1. From Malloc/free to New/delete. This change is the product of the rise of OOP technology. C + + is a strongly typed language,

The main purpose of my article is to introduce the principles of high quality design for a subset of classes and interfaces. These guidelines should not only ensure that the design and implementation of the class or interface itself has high-quality

Overview Pc-lint is a long history, powerful static code detection tool. The history of its use dates back to the ancient times of computer programming (more than 30 years ago). After so many years of development, it can not only monitor a lot of

(1) What is the byte alignment If a variable occupies n bytes, the starting address of the variable must be divisible by n, that is, the starting address% n = 0, and for the struct, this n takes the data type of the member species that occupies the

1 What is POCO? What is POCO? This is the most common question I have been asked. POCO is the abbreviation of portable components, official homepage: pocoproject.org. is a very good C + + library, equivalent to the Java Class Library, the. NET

7.5 Free and delete what's wrong with the pointer?7.7 Eliminate "wild pointer""Wild Pointer" is not a null pointer, it is a pointer to "junk" memory. People generally do not use null pointers incorrectly, because it is easy to judge with an if

7.3.3 Compute Memory capacity You can use operator sizeof to calculate the capacity (in bytes) of the number of groups. In Example 7-3-3 (a), the value of sizeof (a) is 12 (be careful not to forget the ' "). The pointer p points to a, but the value

This article discusses: Unit Test principle Set WinUnit Building test Equipment Implementation and Customization This article uses the following techniques: C + + and visual Studio Directory Start testing Now Getting Started with WinUnit

Review "passive mode" development In C # for game handle Programming development-API (1) In this article we introduced the "passive mode" of development. In this way, our program only acts as a message recipient. The system will regularly tell us

I believe many people have seen the design patterns of the book, What do we experience? Bridge,proxy,factory These design patterns are based on abstract classes. The use of abstract objects is a core here. In fact, I think one of the core problems

The CLR defines some cosmetic elements for access and access that extend beyond the equivalent of class member functions and variables in local C + + (such as public, private, protected), and can even define the accessibility of namespaces or nested

Overview C language has an indeterminate length of the parameters, such as: "...", which is mainly used in the parameters of the uncertainty of the function, our most easily think of the example is the printf function. Prototype: int printf

About "Deep Exploration C + + object Model" Pause for half a month, today continue to chew this bone, my study into the fourth chapter, functional semantics. Let's do a review. C + + supports three member functions: static, Virtual, and non-static.

According to the SGI STL two-level allocation algorithm rewrite the memory pool allocation program, as long as a slight modification can be implemented shared memory mode of management, using the C + + standard storage device in the Map,set,multimap,

Whether reference count pointers are effectively recycled is critical to recovery of data after a system shutdown unexpectedly, and the key is to avoid object duplication. How to recover a long-running, system-level daemon or service from a

A C program consists of a set of external objects, either variables or functions. A function is a self-contained snippet of execution code that completes a certain related function. We can think of a function as a "black box", you just send the data

The checked and unchecked operators control overflow checking in the current environment when used in integer arithmetic operations. The following operations participate in the checked and uncheced checks: Predefined + + and--: unary operator, when

We give a general observer pattern skeleton in the C + + language in the article "Design pattern Observer (Observer) mode and its C + + general implementation (middle)". However, the actual project needs are often more complex than the ideal state,

An MDI (multiple-document interface) application means that a user can open several documents at the same time, and each document appears in a separate window in the client area of the main window of the application. Like word processor word is a

Objective: In Visual C + + programming, sometimes need to use as large as possible areas as a display area, then the full screen display of the program is a good choice, the so-called full screen display, is the program interface without a menu,
