knowing is obsolete :: regular expression generator (perl php python java javascript coldfusion c c++ ruby vb vbscript j# c# c++.net vb.net)
 
 
 
Enter the string that you want to use a regular expression on:
1
   
 
Select the elements that you want to extract to run regular expression generator:
2
4
 4

d2
day2
int42
_

ws_
4
c 4
d4
3
c 3
d3
day3
int
< Source String
What to click?  extract any integer in this position
extract this integer (2006) in this position

//-----
// C does not provide a regular expression feature as standard.
//
// To run this code you will need to first download and install
// the PCRE library from http://www.pcre.org/
//
// Note that on Linux systems PCRE is often already installed in /usr/lib/libpcre* or /usr/local/lib/libpcre*. 
//
// Compile and on Unix using:
// # gcc -lpcre x.c
// # ./a.out
