Regular expression to fetch comments in C using Python

[pikkip]

I am coding a program in Python to fetch comments in a C program( both single and multiline). What regular expression should be used for this?

What have you tried?

I am having issues with lines containing the code and the comment like:

printf("hai)    // prints hai
c = c + 1     /*  htshgbxbvxvbxvxxzv

                        fgdhdhgdghfcncnbc

                  arabcnbchcjc     */

I am not able to categorize the kind of characters that can come up before the comment in 1 and 2. ( . )* doesn't help. Is there any other way to sum up them all rather than specifying them individually?

Well, chek if there is '//' or '*/' in the row. If it is, split the row by '//' or '*/', get the text with in the list which appers to be the comment ( this sould be row[1] ). Then if that is '*/' just take every row until you find '*/'. This is step by step. You can rid off the white space characters using str.strip() function. If you need to.
