De-commenting is one of the primary tasks of the C preprocessor. This article demonstrates a simplified C program to remove comments from source-code.
DFA Design
The deterministic finite state automaton (DFA) expresses the required de-commenting logic. The DFA is represented using the traditional "labeled ovals and labeled arrows" notation. Each oval represent a state. Each state is given short name with detailed descriptions of the left. Each arrow represent a transition from one state to another. Each arrow is labeled with the single character that causes the transition to occur.
Usage
$ ./decomment <file_path>
- If the program is run without argument, the code to be decommented will be read from the standard input and displayed[decommented code] on the standard output
- If argument is given, the code to be decommented will be read form the file and displayed in the standard output.

Build
You can compile the program using gcc.
$ gcc decomment.c -o decomment
Usage
$ ./decomment <file_path>
-
If the program is run without <file_path> argument, the code to be decommented will be read from the standard input and displayed[decommented code] on the standard output
-
If <file_path> argument is given, the code to be decommented will be read form the file and displayed in the standard output.
