Const is the abbreviation of constant, the meaning of "constant unchanged". The const-modified items are protected against accidental changes and can improve the robustness of the program. So many C + + programming books suggest: "Use const whenever

C + + pointers detailedthe concept of pointersA pointer is a special variable, and the value stored in it is interpreted as an address in memory. To make sense of a pointer, you need to be aware of the four aspects of the pointer: the type of

First, open our Visual C + + 6.0 software, I use the Chinese version, the software main interface as shown in:1. Then click on the file in the toolbar, there is a new menu, then we can set up our workspace, as shown in:2. Then click OK in the step

The company has recently been doing a microcontroller and C # language communication. Socket communication is used. The transmitted data is plaintext and later discussed at the meeting is prepared with DES encryption (symmetric encryption) to

With Cocos2dx-lua's classmates, we all know the callback function , in Lua , we can pass a method as a parameter to another method and then call it in the method . But we often have to write C + + code and then turn it into Lua, so how does C + +

TinyXML is an open source parsing XML parsing library that can be used in C + + and can be compiled in Windows or Linux. The model of this analytic library parses the XML file and then generates the DOM model in memory, which makes it easy to

Map is an associative container for STL that provides a one-to-one (where the first can be called a keyword, where each keyword appears only once in the map, and the second may be called the value of the keyword), and because of this feature, it is

C++11 introduced the auto and Decltype keyword implementation of the type deduction, through these two keywords can not only convenient to obtain complex types, but also can simplify writing, improve coding efficiency. The type deduction for auto
