But in C# only concept has been taken from C. But the C# compiler does not have a separate preprocessor, the directives described in this C# are processed as if there was one. Unlike C and C++ directives, you cannot use these directives to create macros. A preprocessor directive must be ...
C preprocessor directives are heavily used in C programs because they provide useful and even necessary additions to the C language. However, they are usually executed and discarded before any analysis is applied on C programs. In refactoring, preprocessor directives must be preserved through the ...

As in C and C++, any numerical value that equals zero is considered "False", and any non-zero value is "True". Ignoring Condition VariablesIf you do not specify a variable's value, then any preprocessor statement that includes that variable is skipped and simply ignored. This is the ...
