how to extract column from text or cel file

[bswapnil]

#include <stdio.h>

void stripnl(char *str) {
  while(strlen(str) && ( (str[strlen(str) - 1] == 13) || 
       ( str[strlen(str) - 1] == 10 ))) {
    str[strlen(str) - 1] = 0;
  }
}

int main() {
  FILE *infile;
  char fname[40];
  char line[100];
  int lcount=1,i=0;
  char mean[100];

  /* Read in the filename */
  printf("Enter the name of a ascii file: ");//input txt or cel file
  fgets(fname, sizeof(fname), stdin);

  /* We need to get rid of the newline char. */
  stripnl(fname);
 /* Open the file.  If NULL is returned there was an error */

      if((infile = fopen(fname, "r")) == NULL)
       {
            printf("Error Opening File.\n");
            exit(1);
      }
  
  
      for(lcount=0;lcount<25;lcount++)
      {
          while( fgets(line, sizeof(line), infile) != NULL)
           {
                 
                printf("%s", line);  
          }
      }
      fclose(infile);  /* Close the file */
}

can anybody help me out how to extract a column from txt or cel file format.....thnxx in advance....

fgets() appends the '\n' to the end of the string, so you have to truncate it before you can use fname to open the file

fgets(fname ...);
if( fname[strlen(fname)-1] == '\n')
    fname[strlen(fname)-1] = 0;

line 36: The answer to your question can be done a couple ways. I would prefer strtok() to extract the words from the line read.

char* word;
word = strtok(line," "); // assume columns are separated by space
while( word != NULL)
{
   // do something with this word
   //
   //
   word = strtok(NULL, " "); // get next word
}

Another way is to use a pointer and iterate through the string.
