Look what happened the last time you cross-posted to clc and clc++.

Pick a language - any language - but pick ONE language, and post to the
newsgroup appropriate to that language.

The problem to which you refer is one of the easier K&R examples, and
should cause you no difficulty.

Men don't talk much about doing "it".

Doing the counts you mention would probably be easier if you wrote three
separate functions, that way you only have one train of thought at a time.

Quit cross-posting between groups. I don't think you will get much help
if you continue this anti-social behavior.

Figure out which language you are working in, then post to that group.

Already done, and (IIRC) published.

We'll be happy to take a look at your solution, any time you wish to
post it

Your choice of names is not very helpful.

I doubt you wanted '=' in there.
In the US, a sentence is usually indicated by ". " , two spaces.

}
printf("\nNo. of spaces = %ld",num);
printf("\nNo. of full stops = %ld",num1);
printf("\nNo. of characters = %ld",num2);
printf("\nNo. of characters without spaces = %ld",num2-num);
printf("\nNo. of sentences = %ld",num3);
return 0;
}

This looks like a draft. I would not think you were happy with it because
of the = above. When you get happy with it, try to improve it. For
example, handle hyphenated words, at least the simple cases. I don't think
they can all be resolved without a dictionary. Following Google rules for
words seems fine to me. AFAIK, they have no rules for sentences.

I tried and it worked. Its fast too.
Counts whitespaces and detects a sentence not ending in '.' as well
(ie: '?' or '!').
perhaps what follows might help:

Try to do what? What are you going to try yourself for?

This program has numerous problems, which I'll be happy to discuss
with you if you pick *one* newsgroup to post to (if that newsgroup
happens to be comp.lang.c; I don't regularly read comp.lang.c++).
C and C++ are two different languages, and cross-posting between
comp.lang.c and comp.lang.c++ is almost never a good idea.

But the first thing you should do is to run the program and take a
look at its output (hint: the results it reports are incorrect).

Sort of. As I recall it, it was characters, words and lines,
not sentences. And K&R made a special point of defining what
they meant by "words" and "lines" (and pointing out that they
were simplistic definitions, which didn't necessarily correspond
to the "intuitive" definition).

So, independantly of the language he choses (C, C++ or
whatever), the first step should be to define exactly what the
code is supposed to do. Until he's done that, he shouldn't
write a single line of code. (Defining a "sentence" in a way
that can be programmed is not obvious, and defining "word" in a
way compatible with everyday use is perhaps not trivial either:
is "don't" one word or two?)

So "Mr. and Mrs. Brown went out." is two sentences, and "I went
out." isn't a sentence.

I suggest that you start by defining exactly what is and what
isn't a sentence (and a word---and you might even ask the
question about characters; I work a lot with UTF-8, where a
character can require several char's).

Don't write a single line of code until you've defined the
problem space precisely.

FWIW: in my own line breaking algorithms, I defined a sentence
as anything ending with [.?!], optionally followed by ["'], and
then any amount of white space (not just ' '). In the context
I'm working in abbreviations aren't a problem; the only one I
encounter in practice is "etc.", and it's easy to special case
that. For learning code, handling abbreviations may be a bit
too complex (but you should at least document the restriction),
but the rest can easily be implemented by means of a simple
state machine.

Define what you mean by sentence more exactly.

IIRC, the definition TeX uses, adopted to the C/C++ character
set, would be:

-- one of [.?!],
-- followed by zero or more of ['"],
-- followed by
. either zero or more whitespace, followed by the end of
file, or
. one or more whitespace, followed by a capital letter.

This works because TeX also expects things like "Mr. Brown" to
contain a non-breaking whitespace ('~' in TeX, 0xA0 in ISO
8859-1), which doesn't count as a whitespace. If you don't
require that, I can't think of anything but special casing to
handle Mr. and Mrs. (and Dr. and... any other abbreviation that
is often followed by a noun).

This is probably most easily handled by some sort of state
machine.
