The C Preprocessor Versus the Compiler
One important thing you need to remember is that the C preprocessor is not part of the C compiler.
The C preprocessor uses a different syntax. All directives in the C preprocessor begin with a pound sign (#). In other words, the pound sign denotes the beginning of a preprocessor directive, and it must be the first nonspace character on the line.
The C preprocessor is line oriented. Each macro statement ends with a newline character, not a semicolon. (Only C statements end with semicolons.) One of the most common mistakes made by the programmer is to place a semicolon at the end of a macro statement. Fortunately, many C compilers can catch such errors.
The following sections describe some of the most frequently used directives, such as
