An XML DTD can actually be viewed as a template for one or more XML files, the elements in these XML files, the attributes of the elements, the arrangement/order of elements, the content that elements can contain, and so on, must conform to the definitions in the DTD. The elements in the XML file, the tags we create, are created based on the actual circumstances of our application. It is difficult to create a highly integrated, adaptable DTD because all walks of life have their own industry char

which is processed by the system reference preprocessor, and the preprocessing part refers to the preprocessing commands that start with "#", which is placed outside the function, and generally placed in front of the source file, such as: command #include, Macro command #define, etc. The reasonable use of preprocessing functions can make the program more convenient to read, modify, transplant, debug, and also conducive to modular programming. This article mainly describes the following sections

The difference between a variable declaration and a definitionWe are in the program design, always use the definition of variables and the declaration of variables, but sometimes we are not very clear about the concept, know how it is used, but do not know how a thing, the following I will simply introduce their differences are as follows: (Hope my guidance to you benefit)There are two scenarios for declaring a variable:1, one is the need to set up st

0. PrefaceFrom the beginning of learning C language began to contact Makefile, consulted a lot of makefile information but always feel no real master makefile, if you write a makefile always feel very laborious. So deliberately using the blog to summarize the relevant knowledge of makefile, through examples to illustrate the specific use of makefile. The example says that makefile roughly divides into 4 parts 1. Only a single C file 2. Contains multiple C files 3. Need to include header file pa
