<lang C++>#include <string>
#include <iostream>
#include <iterator>
#include <fstream>
#include <boost/regex.hpp>
void stripComments( std::string & , const std::string , const std::string ) ;
int main( ) {
std::ifstream codeFile( "samplecode.txt" ) ;
if ( codeFile ) {
boost::regex commentre( "/\\*.*?\\*/" ) ;//comment start and end, and as few characters in between as possible
std::string my_erase( "" ) ; //erase them
std::string stripped ;

Output:
<pre>
Code unstripped:
function subroutine() {
a = b + c ;
}
function something() {
}
