What is C line control?

The C preprocessorC preprocessorWhen the C preprocessor is used with the C, C++, or Objective-C compilers, it is integrated into the compiler and communicates a stream of binary tokens directly to the compiler's parser. However, it can also be used in the more conventional standalone mode, where it produces textual output.https://gcc.gnu.org › onlinedocs › cpp › Preprocessor-Output9 Preprocessor Output - GCC, the GNU Compiler Collection informs the C compiler of the location in your source code where each token came from.

Why do we use preprocessor in C?
The C preprocessor is a macro processor that is used automatically by the C compiler to transform your program before actual compilation. It is called a macro processor because it allows you to define macros, which are brief abbreviations for longer constructs.17 Mar 2001
