Read Text file using c

one more concept is that of a file pointer (FILE *myfile),
while you loop through you need to make sure you don't hit the end of file.

To check that you do

 while(!feof(myfile))
{ //do your job
}
                                                 

thatsks for ur feed back..
actually this is Pro* c program which reads text file and insert data to oracle.

text file format is

|1111|222|333|444|555

in my code i have to read 111 and 444
..
i am trying with folloing code... but it doesnt work..
char            s_data[100];
while(!feof(fp))
      {
            fgets(s_data,150,fp);
            //rech =strtok(s_data,"|");
            strcpy(c_msisdn,strtok(s_data,"|"));
            printf("mobile = %s\n",c_msisdn);            
            
            i= 0;
                               // TO get desired column of data (eg 444)
            while (strtok(s_data,"|")!= NULL)
            {
               // rech = strtok(NULL,"|");
                i = i + 1;
                if (i==4)
                {
                  i_mou = strtok(NULL,"|");;
                }
            }


Thanks for your help...

Two thoughts here:

          while (strtok(s_data,"|")!= NULL)

You need to pass NULL as the string address to perform "continuation searches".  Passing s_data every time means that the search starts at the beginning of the string, and since strtok() has already replaced the first '|' with end-of-string, it will never get to the parameter you want.

char          s_data[100];
char          *position;

while(!feof(fp))
     {
          fgets(s_data,150,fp);
          //rech =strtok(s_data,"|");
          strcpy(c_msisdn,strtok(s_data,"|"));
          printf("mobile = %s\n",c_msisdn);          
           
          i= 0;
    // TO get desired column of data (eg 444)
          position = s_data;
          while (strtok(position,"|")!= NULL)
          {
             // rech = strtok(NULL,"|");
              i = i + 1;
              if (i==4)
              {
                i_mou = strtok(NULL,"|");;
              }
              position = NULL;
          }



You can also do this with sscanf().  One line, two parameters (or more as you may wish) returned.
