C + + array initialization because there are too many methods, and the rules are also confusing, so in the use of the array initialization is often the wrong question, here to the initialization of the array needs to be cautious about the problem of

Recently in the study of C + + polymorphism in the application, which encountered a few questions and problems, but finally the results are indisputable, the following record my learning process to commemorate this point of knowledge.First, it

TypesvoidThe (nonexistent) value of a void expression (an expression of the with type void) shall not being used in any, and Implicit or explicit conversions (except to void) shall is applied to such an expression. If an expression of any other type

1: A conceptual difference between a reference and a pointerA reference is an alias for a variable, such asint m;int &n=m;　　Reference as an alias. It is logically not independent, its existence is dependent, so the reference must be initialized at

I. BACKGROUNDSince the notificationcenter of COCOS2DX itself is not thread-safe, when we use multithreading for message synchronization in COCOS2DX,There is a problem. So in order to solve this problem, we only need a thread security lock.In order

There are three programming languages used in Unity3d: C#,js and Boo. With a free editor at the same time, the editor or VS is the most powerful under Windows, so this article explores how to use VS2008 with Unity3d. 1, create a Unity3d project, and

C Language FunctionsFirst, the functionC language programs are composed of functions, each function is responsible for the completion of a part of the function, the function will be the work of the package, for the program to call.Second, function

When the interfaces of Python and C + + involve buffers, you can create buffers in Python and pass pointers to the buffers to C + + functions (by creating additional functions for conversion). Examples are as follows:Python side:1. Get the binary

Note: The conclusion given in this paper is the result of debugging under VS2010.First, the problem introducedThe following four classes are typical of the basic structure of C + + virtual inheritance, and the question now is how much is the sizeof

1. Definition of pure virtual function:(1) A function that the virtual function is "initialized" to 0. The general form of declaring a pure virtual function isvirtual function type function name (parameter table column) = 0;(2) The pure virtual

C-language operatorsFirst, arithmetic operationsThere are 34 types of operators in C, including common subtraction operations.①. Addition: + can also indicate a plus sign②. Subtraction:-can also represent a minus sign③. Multiplication: *
