EXAMPLE

  #include <ctype.h>
  #include <stdio.h>
  #include <stdlib.h>

  main()
  {
     char filename[60];
     int words = 0, lines = 0, bytes = 0;
     int spacing = 1;
     int ch;

     puts("Enter the input file name:");
     memcpy(filename, "tso:", 4);
     gets(filename+4);
     if (freopen(filename, "r", stdin) == 0){
        puts("File could not be opened.");
        exit(EXIT_FAILURE);
     }

        /* Read the file and count bytes, lines, and words. */
     for(;;){
        ch = getchar();
        if (ch == EOF) break;
        ++bytes;
        if (ch == 'n') ++lines;

           /* If the input character is a nonspace character */
           /* after a space character, start a new word.     */
        if (isspace(ch)) spacing = 1;
        else if(spacing){
           spacing = 0;
           ++words;
        }
     }
     printf("The input file contains %d bytesn", bytes);
     printf("%d lines and %d words.n", lines, words);
     exit(EXIT_SUCCESS);
  }
