What to click?  extract any integer 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
