{
   FILE *fp;
   char c;
   int nc=0,nw=0,nl=0;
   fp=fopen("hello.txt","r");   /* hello.txt is already existing file */
   if(fp==NULL)
   {
     printf("\n file does not exist");
    }
    while((c=getc(fp))!=EOF)
     {
            nc++;
            if(c==' ')
             nw++;
            if(c=='\n')
            nl++;
      }
      printf("\n number of characters=%d\n number of words=%d\n number of lines=%d",nc,nw,nl);
 }
OUTPUT:
              no of characters=25
