There are a lot of arguments about the advantages and disadvantages of C # And C ++, and I don't like such arguments. It seems that I have to let the other party die and then go fast. Our great Chairman Mao said: The Hundred Flowers are fighting and the Hundred Flowers are playing together. Deng Xiaoping, chief designer of reform and opening up, also said: black cats and white cats are good cats. (Haha, it'
The C ++ standard library is very large. Incredible big. How can this problem be solved? In the C ++ standard, the specification descriptions of the standard library account for more than 300 pages. This does not include the standard C library, the latter is only included in the C ++ library as a reference. Of course,
In the recent learning of C # Programming Foundation, and before have learned C language, this can not help but let me wonder: C language and C + +, C # What is the difference?After inquiring the information, I summed up the difference between them:C/

Preface
Start TimeI learned C #2.0 and didn't fully learn it. After work, I am either busy with projects, or have a taste of various technologies, but I have no progress in language learning. It wasn't until six months ago that I started getting started with Python (purely a hobby, and I learned it intermittently) that I could do the same for programming!

In actual project development, users often encounter situations that require high performance while delivering a comfortable user experience. Therefore, C # serves as the GUI front-end. C ++ becomes a perfect combination for background communication. For example, C ++ calls the camera API and then returns the stream to the GUI client to display the camera content

Try to write the following C/C ++ pointer operation code in three. Net methods. Note that all. Net methods do not directly reference external function resources (dllimport). They are all provided by the. NET ecosystem.
Note: All code outputs only represent the running results in the 32-bit and little-Endian CPU environments.

0 origin of the problemThe consideration of this problem comes from the implementation of the single-instance design pattern in object-oriented design.The standard code for the singleton pattern implementation in C + + is:#include In the Get instance function gettheonly (), the static local variable user stores a unique instance and initializes it dynamically using the init () function directly.It seems so simple, but the same code is compiled as

(2) The colon following the constructor acts as a segmentation function. It is a class-based method for assigning values to member variables. The initialization list is more suitable for the constant const type of member variables.
Struct _ XXX {

The UE editor has always been a good helper for programming and editing texts. The most profound feature of its image is the column mode editing function, which brings a lot of convenience to my work, however, being a programming tool without formatting the source code seems to make ue less beautiful, but this is not the case, two open-source command line tools provided by UE can well format the source code of several popular program

Object-C is actually a language for embedding runtime-level Object calls in C or C ++ code!
What is a running-level object call, that is, an object call is not at the syntax level, but at the runtime level after compilation. Similar technologies include Microsoft's COM and open Object Organization's Corba
