May 15, 2011 · Most compilers will allow you to define a macro from the command line (e.g. g++ -DDEBUG something.cpp), but you can also just put a define in your code like so: #define DEBUG Some resources: Wikipedia article; C++ specific site; Documentation on GCC's preprocessor; Microsoft reference; C specific site (I don't think it's different from the C++ ...
Mar 7, 2017 · 2. If you want the code represented by the second comment section to always run, just do. #ifdef PROC_ADD. // Do the stuff to be done if PROC_ADD is defined. #undef PROC_ADD. #endif. // Do the stuff to always be done. If you want run-time behaviour changes, you must use run-time constructs (such as a variable to serve as a flag).
A good way to understand what the preprocessor does to your code is to get hold of the preprocessed output and look at it. This is how to do it for Windows: Create a simple file called test.cpp and put it in a folder, say c:\temp. Mine looks like this: #define dog_suffix( variable_name ) variable_name##dog. int main()
Nov 27, 2015 · The #define directive has two common uses. The first one, is control how the compiler will act. To do this, we also need #undef, #ifdef and #ifndef. (and #endif too...) You can make "compiler logic" this way. A common use is to activate or not a debug portion of the code, like that: #ifdef DEBUG. //debug code here.
Jan 2, 2018 · Java doesn't have a general purpose define preprocessor directive. In the case of constants, it is recommended to declare them as static finals, like in. private static final int PROTEINS = 100; Such declarations would be inlined by the compilers (if the value is a compile-time constant).
Oct 30, 2013 · 14. In C# #define macros, like some of Bernard's examples, are not allowed. The only common use of #define / #if s in C# is for adding optional debug only code. For example: static void Main(string[] args) //this only compiles if in DEBUG. Console.WriteLine("DEBUG") //this only compiles if not in DEBUG.
As far as I know, what you're trying to do (use if statement and then return a value from a macro) isn't possible in ISO C... but it is somewhat possible with statement expressions (GNU extension).
DEFINE is a preprocessor instruction (for example, #define x 5). The compiler takes this value and inserts it wherever you are calling x in the program and generate the object file. "Define" constants don't create a symbol entry in symbol table. If you wanted to debug the program, you would not find x. Use constant where ever possible that what ...
Dec 21, 2011 · There is no concept of types within the preprocessor. Suppose that you have the following lines in your source file: #define MAXLINE 5000. int someVariable = MAXLINE; // line 2. char someString[] = "MAXLINE"; // line 3. The preprocessor will detect the macro MAXLINE on line 2, and will perform a text substitution.
Jul 12, 2011 · 12. You can create an empty two dimensional list by nesting two or more square bracing or third bracket ([], separated by comma) with a square bracing, just like below: Matrix = [[], []] Now suppose you want to append 1 to Matrix[0][0] then you type: Matrix[0].append(1) Now, type Matrix and hit Enter.
