- #defining constants in C++ - Stack Overflow
54 Is it considered bad programming practice to #define constants in C++? Yes, because all macros (which are what #define s define) are in a single namespace and they take effect everywhere Variables, including const -qualified variables, can be encapsulated in classes and namespaces
- c++ - static const vs. #define - Stack Overflow
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?
- Where to declare define class scope constants in C++?
In other words, when it comes to non-integral constants, a normal practice is to define them in cpp file So, regardless of how you declare it (in the class or out) you will normally always have to deal with the "detriment" of having to define it in cpp file
- C++ Best practices for constants - Stack Overflow
The only alternative is to make your constants extern and define them in another cpp file, but you'll lose potential for optimization, because the compiler won't know what value they have when compiling each cpp` By the way, don't worry about the size increase: for integral types your constants are likely to be inlined directly in the generated machine code Finally, that static is not
- Understanding how to correctly treat c++ class constants
Constants that are not of integer type should be defined as static const members (but you will have to be careful of the order of static initialization if there are any other static objects that refer to these constants) Constants of integer type can either be declared as static const int or as enums, as you already mention
- Define constant variables in C++ header - Stack Overflow
A program I am working on has many constants that apply throughout all classes I want to make one header file "Constants h", and be able to declare all the relevant constants Then in my other cla
- How to correctly define constants in C++ - Stack Overflow
Is my understanding correct - multiple instances of myConstant are created? If this is the case can you please point me to better alternatives of using constants in C++ EDIT: Some suggested to make myConstant extern in the header and define it in one cpp file Is this a good practice?
- c++ - Why would someone use #define to define constants . . . - Stack . . .
53 #define has many different applications, but your question seems to be about one specific application: defining named constants In C++ there's rarely a reason to use #define to define named constants #define is normally widely used in C code, since C language is significantly different from C++ when it comes to defining constants
