Please help me

Couldn't you just read the file in line after line until you get a line that says "end_header" and nothing else? From there, reading in floats/doubles is easy.

Also, do you know how to use ifstreams? If not, here's a link:

Good luck!

Thank you very much for the reply. I have written this code but I dont know how to get values of x, y and z only. I mean the numbers then save them into a file. Can u plz check my code below:

#include <iostream.h>
#include <fstream.h>
#include <stdlib.h>

int main () {
  char buffer[256];
 
  ifstream examplefile ("test.txt");
 
  if (! examplefile.is_open())
  { 
     cout << "Error opening file"; 
     exit (1); 
  }

  while (! examplefile.eof() )
  {
    examplefile.getline (buffer,100);
   if (buffer!="end_header");
//read x, y and z 

  }
  return 0;
}
