Although the compiler doesn't have a separate preprocessor, the directives described in this section are processed as if there were one. You use them to help in conditional compilation. Unlike C and C++ directives, you can't use these directives to create macros. A preprocessor directive must ...

Preprocessor directives are used to affect or direct the code that's received by the compiler. For example, consider the following code sample: → WrapCopy #if HAVE_LONG_LONG == 1 #define BALANCE_TYPE long long #else #define BALANCE_TYPE double #endif ... BALANCE_TYP...
The#if,#elseand#elif(i.e., "else if") directives serve to specify some condition to be met in order for the portion of code they surround to be compiled. The condition that follows#ifor#elifcan only evaluate constant expressions, including macro expressions. For example: ...
`#if` statement, for example. however, it is important to note that the directives must be properly closed off with an equal number of `#endif` statements. failure to do so can lead to unexpected behavior and errors. can preprocessor directives be used with other languages besides c/c++?
The GNU C preprocessor is used by the gcc compiler to preprocess the source files.In the preceding link, you can find how the preprocessor parses the directives and how it creates the parse tree. The document also provides an explanation of the different macro expansion algorithms. While it ...
Learn about the C++ preprocessor, its directives, and how to use it effectively in your C++ programming.
which would result in 1 * 5 being evaluated before the addition, not after. Oops! It is also possible to write simply #define [identifier name] which defines [identifier name] without giving it a value. This can be useful in conjunction with another set of directives that allow conditional...
~ swim ~ Gave you and example of preprocessors for C/C++. What you put in the tag. In Visual Studio "Release" and "Debug" are part of the project configurations not directive. Since it is still unclear if you are using the correct terms or not, I will guess what you are doing. In...
