Mar 10, 2011 · If they're both strings you can just do: #define STR3 STR1 STR2. This then expands to: #define STR3 "s" "1". and in the C language, separating two strings with space as in "s" "1" is exactly equivalent to having a single string "s1". edited Nov 3, 2020 at 8:12.

Mar 11, 2014 · 5 Answers. Sorted by: 2. You can generally use the ## (double number sign) to concatenates two tokens in a macro invocation. However, since you have string literals jamming an already defined macro, you could just use spaces, else you could run into invalid preprocessing token. Also, you should escape your backslash.
Nov 15, 2009 · The compiler will automatically concatenate adjacent strings: #define ROOT_PATH "/home/david/". #define INPUT_FILE_A ROOT_PATH "data/inputA.bin". Or more generic: #define INPUT_FILE_DETAIL(root,x) root #x. #define INPUT_FILE(x) INPUT_FILE_DETAIL(ROOT_PATH "data/", x) edited Nov 15, 2009 at 22:43. answered Nov 15, 2009 at 22:35.
How can I write a combine function for an R foreach() statement that uses itertools chunking such that I get the same result as using the R foreach() statement without itertools chunking? I have an R foreach() statement that performs a calculation and returns a list of three lists.
A primary key consists of one or more columns (from that table). If a primary key consists of two or more columns it is called a composite primary key. It is defined as follows: CREATE TABLE voting (. QuestionID NUMERIC, MemberID NUMERIC, PRIMARY KEY (QuestionID, MemberID) ); The pair (QuestionID,MemberID) must then be unique for the table and ...
Dec 6, 2014 · First let's define the types. interface ClientRequest { userId: number sessionKey: string } interface Coords { lat: number long: number } Now the combination of both: type Combined = ClientRequest & Coords; Assuming you have two existing objects which you would like to pass to the function:
String literals can be concatenated this way "str1""str2". macro function can concatenate two string literals - #define STRCAT(str1, str2) str1##str2. And when it comes to variables, you use strcat() More efficient approach is to use string managing utilities such as GString. It keeps track of the end of string and it handles memory expansions ...
May 1, 2020 · I would like to define a macro to concat __func__ (or __FUNCTION__) with __LINE__: The following works fine: // macro_test.cc #include <iostream> #define STR2(X ...
May 20, 2023 · You need expand __LINE__ in two levels, before passing it to #x. First of all, using operator # in a function-like macro, it has to be followed by a macro parameter but __LINE__ is not a parameter, so compiler complains it's a stray operator. On the other hand, __LINE__ itself is a macro and contains current line number, it should be expanded ...
Sep 23, 2014 · What they do is put everything on a single line, so the expanded macro will look something like. int main() {. #ifndef DEBUG_MODE ; #else cout ...; #endif. } This will not work very well with the preprocessor or the compiler. Instead you should switch the nesting, and use #ifndef first, and #define the macros in the inner level.
