Define Ip Address Specify Ipv4 Address Class With Their Address Ranges Bench Partner There are multiple problems with your macro: it expands to a statement, so you cannot use it as an expression the arguments are not properly parenthesized in the expansion: invoking this macro with anything but variable names or constants will produce problems. the arguments are evaluated multiple times: if you invoke the macro with arguments that have side effects, such as sum a(a(), b()) or.

Define Ip Address Specify Ipv4 Address Class With Their Address Ranges Bench Partner What is the point of #define in c ? i've only seen examples where it's used in place of a "magic number" but i don't see the point in just giving that value to a variable instead. 0 in c or c #define allows you to create preprocessor macros. in the normal c or c build process the first thing that happens is that the preprocessor runs, the preprocessor looks though the source files for preprocessor directives like #define or #include and then performs simple operations with them. The #define version is still a macro. the code is expanded at the invocation site. it has all the expected problems (with macros) including namespace pollution and unexpected parameter behaviour. Is it better to use static const variables than #define preprocessor? or does it maybe depend on the context? what are advantages disadvantages for each method?.

If you forget to define something that's been declared and referenced somewhere, then the linker doesn't know what to link references to and complains about a missing symbols. if you define something more than once, then the linker doesn't know which of the definitions to link references to and complains about duplicated symbols. The #define directive is a preprocessor directive; the preprocessor replaces those macros by their body before the compiler even sees it. think of it as an automatic search and replace of your source code. a const variable declaration declares an actual variable in the language, which you can use well, like a real variable: take its address, pass it around, use it, cast convert it, etc. oh. @topher217 'dict' and 'list' are actually the class names. i believe that's to distinguish built ins from non built ins as apposed to primitive vs non primitive. user defined types are typically pascal case. python likely derived this naming scheme from c or c . in c structs are typically lower case (though there are a lot of people that use pascal case), and in c people typically use.
