A compilation unit refers to a C source code which is compiled and treated as a single logical unit. It is generally one or more complete files; however, it also may be a certain part of a file if the #ifdef preprocessor directive is applied to choose specific code sections. Advertisemen...
Here, n is used as a symbolic constant which is defined using preprocessor directive #define. It is initialized to a value 20 so the size of the array s is 20. Access Array Elements Initialization of Array Access Array Elements Once the array is created, you can access an array element ...
The first thing you will notice is the first line of the file, the #include "stdio.h" line. This is very much like the #define the preprocessor , except that instead of a simple substitution, an entire file is read in at this point. ...
The task enables you to reformat inactive preprocessor branches. It can only be applied to the entire file at once and works only with C# sources. This task cannot reformat code hidden behind a preprocessor directive #if that is always false. The two most obvious examples of this limitation...
enum defines a syntactical element. #define is a pre-preprocessor directive, executed before the compiler sees the code, and therefore is not a language element of C itself. Generallyenums are preferred as they are type-safe and more easily discoverable. ...
