Step by step solution

01

Preprocessor directives are special commands that are processed by the compiler before the actual compilation process begins. These directives provide instructions to the compiler for specific tasks, such as including external files or defining macros. #Step 2: Identifying the Beginning of Preprocessor Directives#

Preprocessor directives begin with a hash symbol (#). This symbol tells the compiler that the line is a preprocessor directive and should be handled accordingly. Some common examples of preprocessor directives are #include, #define, #ifdef, #ifndef, etc.
