　　They have a common advantage is "change the whole, to avoid the input error" What are the two different? Some.The main difference is that the macro definition is done prior to compilation, and the const is processed during the compilation phaseMacros define constants that do not occupy memory cells and are defined by const occupy memory unitsA macro definition has the same effect as a const constant-----t

OC-class definition and oc-DefinitionWe have already introduced a program HelloWorld: Keep in OC. The biggest difference between OC and C is that it has the Object-Oriented function. When it comes to object-oriented, we have to talk about the class concept. If we have learned Java, so there is no stranger to the concepts of classes and objects, Because Java is a very pure object-oriented design language. I will not elaborate on the concepts of classe

To write a good C language, a beautiful macro definition is very important. Macro definitions can help us prevent errors, improve code portability and readability, and more.In the software development process, there are often common or common functions or code snippets that can be written as functions or encapsulated as macro definitions. So is the function good or the macro definition good? This requires u
