when i start running the program, i can't exit while loop when input character, so the program isn't print the value of nc.

  #include <stdio.h>
  main()
  {
     long nc;
     nc=0;
     while(getchar()!=EOF)
     ++nc;
     printf("%ld\n",nc);
  }

EOF is checking for the end of a file, your not working with files.

While that is what the acronym stands for, EOF is used for the end of streams in general, not just the end of file streams.

If you're in a Windows console, you can terminate input by pressing Ctrl+Z - this will end the input stream completely.
