Macros can be used to define reusable code snippets from "summary" of C Programming Language by Brian W. Kernighan,Dennis Ritchie
Macros are a powerful feature in C that can be used to define reusable code snippets. Instead of writing the same code over and over again, we can define a macro that represents that code and then use it wherever needed. This saves us time and effort, and also helps in keeping our code concise and readable. When we define a macro, we are essentially creating a shortcut for a piece of code. This can be handy when we have a complex or frequently used code block that we want to simplify. By defining a macro, we can abstract away the details of the code and make it easier to understand and use in different parts of our program. One important thing to keep in mind when using macros is that they are replaced by the preprocessor before the actual compilation process begins. This means that every time the macro is used, it is substituted with the code it represents. This can...
