[QUOTE="Dr Nick, post: 5021682"]
The second statement should do something - because it should always be
true.  Think about it - if c is a space it isn't an newline or a tab,
and if it's a newline it isn't a space or a tab, and if it's an 'x' it
isn't a space, or a newline, or a tab.  You need && in there - you need
all the conditions to be true, not just one of them.

There is a useful function (in ctypes.h) for this - called "isspace".
So you can replace your pieces of code with:
#include <ctypes.h>
....
if(isspace((unsigned char)c) {then go to next character }
else ( increase no of word}

and
if(!isspace((unsigned char)c)
{ increase no of word}

The "(unsigned char)" bits are in for technical reasons; they prevent
the isspace function doing something silly if you pass an unusual value
to them (like and end of file, or perhaps certain accented characters
depending on various other things).  They make it slightly less elegant,
but it's still tidier and will be familiar to experienced programmers.
