Problem in text management while file handling

[ajain]

hi all...this is urgent..i need to rearrange the content of a text file which looks like:

Terminal log file
Date: 21/11/2006 - 6:17:04 PM
-----------------------------------------------
01 02 01 01 00 4B 00 38 46 24 12 01 02 01 01 00
4B 00 38 46 24 12 01 02 01 01 00 4B 00 38 46 24
12 01 02 01 01 00 4B 00 38 46 24 12 01 02 01 01

01 01 00 4B 00 38 46 24 12 01 02 01 01 00 4B 00
38 46 24 12 01 02 01 01 00 4B 00 38 46 24 12 01

00 38 46 24 12 01 02 01 01 00 4B 00 38 46 24 12
--------------------------------------------------------------------------


i've to arrange it like: and save it in a new file in the format:

Terminal log file

i cant maintain the required alignment. i've written the following code in C AND I'M USING A TURBO C ASSEMBLER. Please suggest me the required corrections in my code. Here is my code:

 #include<stdio.h>
      #include<conio.h>
 
      void main (void)
      {FILE *f1, *f2;
       char n;
       int i,k;
 
       clrscr();
 
       f1 = fopen("c:\\turboc3\\a.log","r+");
       if(f1==NULL)
       {printf("cant open file");
    getch();
       //    exit();
       }
       f2 = fopen("c:\\turboc3\\N.log","w+");
 
       for(i=0;i<96;i++)
       {n=getc(f1);
       putc(n,f2);
       printf("%c",n);
       }
 
 
       if(kbhit())
        {
         if((n=getch())==27)
         exit (0);
        }
       else
        {while((n=getc(f1))!= EOF)
          {
          for(k=0;k<=47;k++)
        {
           for (i=0;i<32;i++)
            { n = getc(f1);
              if(n =='\n')
            { fprintf(f2,"");
              printf(" ");
            }
              else
            { fprintf(f2,"%c",n);
              printf("%c",n);
            }
           }
           fprintf(f2,"\n");
        }
          fprintf(f2," ") ;
          }
      }
 
 
 
     fclose(f1);
     fclose(f2);
 
     getch();
    }
 

if somebody wants..i can post the actual file that i am using....

perhaps your requirement is more complicated than it looks but it I think a much simpler program would do what you require, e.g.

#include<stdio.h>
      #include<conio.h>
 
      int main (void)
      {FILE *f1, *f2;
       char n;
       f1 = fopen("a.log","r+");
       if(f1==NULL)
       {printf("cant open file");
    getch();
       //    exit();
       }
       f2 = fopen("N.log","w+");
     int count=0;
     while((n=getc(f1))!= EOF)
          {
           if(n < ' ') n= ' ';  // replave \n with a space
           fprintf(f2,"%c",n);  // output the character
           printf("%c", n);
           // if at end of line output a \n and reset count
           if(++count == 33) { printf("\n"); count=0; }
          }
     fclose(f1);
     fclose(f2);
     getch();
    }

thanx sir...perhaps the code is good...but it doesn't gives the rightly formatted output....do u hav ne clue where m i going wrong....?

thanx sir...perhaps the code is good...but it doesn't gives the rightly formatted output....do u hav ne clue where m i going wrong....?

the screen output was OK but I did not output a newline to the n.log file

program should be

#include<stdio.h>
#include<conio.h>
 
int main (void)
{
    FILE *f1, *f2;
    int count=0;
    char n;
    f1 = fopen("a.log","r+");
    if(f1==NULL)
       {printf("cant open file");
          getch();
           return 1;;
       }
     f2 = fopen("N.log","w+");
     while((n=getc(f1))!= EOF)
          {
           if(n < ' ') n= ' ';  // replave \n with a space
           fprintf(f2,"%c",n);  // output the character
           printf("%c", n);
           // if at end of line output a \n and reset count
           if(++count == 33) { printf("\n"); fprintf(f2, "\n"); count=0; }
          }
    fclose(f1);
    fclose(f2);
    getch();
    return 0;
}
 

when I run using Turbo C with your data the n.log file contains
01 02 01 01 00 4B 00 38 46 24 12
01 02 01 01 00 4B 00 38 46 24 12
01 02 01 01 00 4B 00 38 46 24 12
01 02 01 01 00 4B 00 38 46 24 12
01 02 01 01 00 4B 00 38 46 24 12
01 02 01 01 00 4B 00 38 46 24 12

01 02 01 01 00 4B 00 38 46 24 12
01 02 01 01 00 4B 00 38 46 24 12

is that correct?

[ajain]

thnx i checked the code...it is absolutely alrite...i made a new log file and tried running it and it worked well , but it is not running on my actual log data.
is it possible that i show u the actual log sheet, its a long .log file
wwll also cud u tell me the meaning of this line of code that u used?

if(n < ' ') n= ' ';  // replave \n with a space

    f1 = fopen("a.log","r+");
    if(f1==NULL)
       {printf("cant open file");
          getch();
           return 1;;
       }
     f2 = fopen("N.log","w+");
     while((n=getc(f1))!= EOF)
          {
           if(n < ' ') n= ' ';  // replave \n with a space

wwll also cud u tell me the meaning of this line of code that u used?

if(n < ' ') n= ' ';  // replave \n with a space
 

can you attach or email the log file?

the line

if(n < ' ') n= ' ';  // replave \n with a space
 

should read

if(n < ' ') n= ' ';  // replace control characters  with a space
 

any character with a character code less than ' ' (space) are replaced with a ' ', i.e. it is to remove newline, etc.

[ajain]

yes i can mail u the xact log file.but i dont find an option to attach files here.

can you attach or email the log file?

the line

if(n < ' ') n= ' ';  // replave \n with a space
 

should read

if(n < ' ') n= ' ';  // replace control characters  with a space

i am sorry for the second post,
sir i hav mailed u the log files at the adress specified in ur profile.plz confirm if recieved.

The problem is dealing with text before and after the numerical data. You have to look for it and output it to the output file unchanged. Lines with numeric data are formatted as required.

try this version

#include<stdio.h>
#include<conio.h>
#include <ctype.h>
 
int main (void)
{
    FILE *f1, *f2;
    int count=0;
    int checkDigit=1;
    char n;
    f1 = fopen("a.log","r+");
    if(f1==NULL)
       {printf("cant open file");
          getch();
           return 1;;
       }
     f2 = fopen("N.log","w+");
     while((n=getc(f1))!= EOF)
          {
           if(n == '\n') // if newline check next character is a digit
              { 
               // if last line was non digital output a newline
               if(checkDigit > 0) { printf("\n"); fprintf(f2, "\n"); }
               checkDigit=1;    // check next character is a digit
              }
           if(n >= ' ')           // if not a control character
             {
              fprintf(f2,"%c",n);  // output the character
              printf("%c", n);
              // if last character was a newline check if this character is digit
              if(checkDigit == 1) 
                    // if is is NOT set CheckDigit = 2 else 0
                   if(!isdigit(n)) checkDigit=2; else checkDigit =0;
              // if outputing digits check if we need a newline
              if(checkDigit == 0)
                 // if at end of line output a \n and reset count
                 if(++count == 33) { printf("\n"); fprintf(f2, "\n"); count=0; }
             }
         }
    fclose(f1);
    fclose(f2);
    getch();
    return 0;
}

thanks horace, thats an impeccable code. Has very well solved my purpose.
