Using the UnderC Tokenizer Class It s often necessary to parse complex text files, where standard

#include <iostream.h>
#include "tokens.h"

int main(int argc, char**argv)
{
 Tokenizer tok;
 if (! tok.open(argv[1])) return 1;
 int knt = 0;
 double xsum = 0.0, ysum = 0.0, zsum = 0.0;
 while (tok.go_to("points")) {
  char ch;
  do {
    xsum += tok.next_float();
    ysum += tok.next_float();
    zsum += tok.next_float();
    ch = (char)tok.next();
    if (ch == ')') ch = (char)tok.next();
    knt++;
  } while (ch != ';');
 }
 cout << "av x = " << xsum/knt << ' '
      << "av y = " << ysum/knt << ' '
      << "av z = " << zsum/knt << " for " << knt << " points" << endl;
 return 0;
