// C++ does not provide a regular expression feature as standard.

// To run this code you will need to first download and install

// 
// Note that on Linux systems PCRE is often already installed in /usr/lib/libpcre* or /usr/local/lib/libpcre*.

// Compile and run on Unix using 
// # c++ x.cpp -lpme -lpcre 
// # ./a.out
