JSON (JavaScript object Notation, JS tag) is a lightweight data interchange format. Typically used for data exchange or storage.Jsoncpp is a C + + language-based open source Library for C + + program JSON data read and write operations.Jsoncpp is an

C + + uses public, protected, private three keywords to control the access rights of member variables and member functions, each of which represents a common, protected, private, called member access qualifier. The so-called access permission is

The pointer to the pointer, the pointer variable, and the memory variable that the pointer points to are different. Constant assignment of pointers is the equivalent of constantly changing the direction of the pointer.In the development to avoid the

? during the development of a derived class, the base class member is manipulated by the access control of the base class member in the base class.？C + + provides the following methods of code reuse:1. Inheritance ( public inheritance (IS-A),

Translated from: http://www.cnblogs.com/ymy124/p/3632634.htmlFirst, the explicit keyword in C + + can only be used to decorate a class constructor that has only one argument, which is to show that the constructor is displayed, not implicitly, and

You can declare a multidimensional list array in the following way, but it is not recommended to use the?For a one-dimensional array:list variable = new list ();list allints = new list ();?Simple two-dimensional arrays and three-dimensional

Sealed Sealing classCannot be inherited by other classes, but can inherit other classes.1. Sealed keywordWhen the sealed modifier is applied to a class, this modifier prevents other classes from inheriting from the class. Similar to the final

The so-called function is a code that has a separate function and can be reused by name. The function should pay special attention to the declaration before the call. and the declaration position of the function must be in the class.The syntax for a

Memset functions and precautions: memset Functions The prototype of the memset function is void * memset (void * ptr, int value, size_t num). It is used to assign values to the num bytes starting with the address ptr. The header file of the memset
