But I could find the similar method.



I see some documents say that we can use "$" to get the group reference, and it doesn't explain more.



Well, I read lines from text, and use "^(d+)s+3(7)0-21(s+ds+)6"
to find the matched line.
And then I need to replace the 39[0-2] to be 37[0-2].
It can be done by minus 20 or other ways which I don't care.

Well,@Ctorres gives me an idea now.



When I get the matched line,put it in a char array.



First we skip the array first number,and blank spaces.



Then change the char'9' to be '7'.



But I think it's really complex.
