The preprocessor performs preliminary operations on C and C++ files before they are passed to the compiler. You can use the preprocessor for

File inclusion, in which the file being preprocessed incorporates the contents of another file, exactly as if the included file’s text were actually part of the including file;
Macro substitution, in which one sequence of text is replaced by another;
Conditional compilation, in which parts of the source file’s code can be eliminated at compile time under certain circumstances.
