  hi friends i faced a problem that is in the simulation of a processor my task is to print the purpose of each and every word and characters i mean
  

  printf("hi is nani");

  in the above code it is a line of c program which is the input file to my program
  in that i want to explain as
  
  like that my output would be.
  but i am facing the problem at tokenizing the sentence in the line there is no delimiter between 'printf' and '('(opening brace) then how could i do that
  thanks in advance waiting for ur replies

  Sorry Raviteja, but i could not get you that why you need a delimiter to tokenize only printf and (. Is there any boundations that you have to do so only? Will your input file always consist of printf type statements followed by ( ?
  
  If you can be more generic to your requirement, may be we can be of some help to you. 😀

  the input file to mu program is a [dot]c file.
  so it would definitely contain printf statements followed by ( .
  and my program is to design a program which gives the output explaining each and every word with special characters included.
  my program will be as follows:
  

  import java.io.*;
  import java.util.*;
  import java.lang.*;
  class cp
  {
  static StringTokenizer st;
  public static void main(String args[])throws IOException
  {
  File f1=new File("input.dat");
  FileReader fr=new FileReader(f1);
  BufferedReader br=new BufferedReader(fr);
  File f2=new File("con.txt");
  FileReader fr1=new FileReader(f2);
  BufferedReader br1=new BufferedReader(fr1);
  String s[]={"#include","main","{","int",";","}"};
  int i=0,j,p=0;
  String a[ ]=new String [100];
  String b[ ]=new String [100];
  String c[ ]=new String [100];
  do
  {
  a=br.readLine();
  i++;
  }while(a[i-1]!=null);
  for(j=0;j<(i-1);j++)
  {
  st =new StringTokenizer(a[j]);
  while(st.hasMoreTokens())
  {
  b[p]=st.nextToken( );
  p++;
  }
  }
  i=0;
  do
  {
  c=br1.readLine();
  i++;
  }while(c[i-1]!=null);
  for(i=0;i {
  for(j=0;j<6;j++)
  {
  if(b.equals(s[j]))
  {
  System.out.println(c[j]);
  if(j==3)
  System.out.println(b[i+1]+" is a integer variable");
  }
  }
  }
  }
  }
  

  
  and the input file is
  

  #include
  main {
  int a ;
  printf("hi is nani");
  }

  the above wouldn't work with files more than three lines u can understand that and my problem is tokenizing the instruction line to strings for which delimiters are required
  i think u can understand now
