NEED HELP WITH A PROGRAM....ANYONE PLEASE HELP!

QUESTION:
Write a program that opens and read a text file and records how many
times each word occurs in the file. Use a binary search tree modified
to store both a word and the number of times it occurs. After the
program has read the file, it should offer a menu with three choices.
the first is to list all the words along with the number of occurences.
The second is to let you enter a word, with the program reporting how
many times the word occured in the file. The third is to quit.

This quesiton is from the book C Primer Plus 5th edition by Stephen
Prata. Chapter 17 question 7. I read the chapter twice and can't figure
out how to write this program. Is there anyone out there who can give
me the code for this program. I am desperate. Maybe I could pay whoever
can give me the code.

Forget about the binary search tree.
Write the program so that it goes throught he file, picks out the words, and
stores the count of each word in a flat list. If it helps, set a limit of
10000 distinct words.

Then come back with what you've done and start on the binary tree bit.

how would that help you? You learn to program by writing programs. As
another poster suggested, tackle a slightly simplified version of the
program
and then add to it.

For instance
open file
read lines
close file

the process the lines to extract words. First decide what a word is
(eg. a
sequence of non-whitespace terminated by whitespace, whitespace is
space, newline or tab).

and so on. Learn by doing, take small steps

If this is for homework, the following won't help you at all. If
you just want to learn things, try the wdfreq usage demonstration
in my hashlib package. See:

You don't say where your problem is. I don't have that book but based on
other books by that author, I would expect that I would like it. If you
have been going through the book - not attacking it in the center, for
example - the only problem I would expect would be the requirement to use a
tree. Chapter 17 sounds like you are well into the book and doing the file
business and isolating a word should be relatively easy for you by now, or
at least doable. This is the data structure I would use for a single node
in the tree, see if it kick starts your mind. Main has a pointer to the top
node of the tree.

struct S
{
char* wd;
int ct;
struct S* left_child;
struct S* right_child;
};

Well maybe you could help me with the first 15 lines of the code.....i
dont know how to start the program......and no i havent gone through
the entire book. Our school was out cuz of the teachers strike happened
for 3 weeks during school period. Now in order for me to pass the
class......teacher want us to do this question. Hes on vacation now so
i cant ask him for help. Its due in two weeks and i've emailed other
teachers too but no reply yet!

Break the problem down into pieces. Defer the menu until much later, write
the program as though the user choice was the first choice listed, list all
the words and the counts. You need a test file, best put into the same
directory your source code will be in. You could cut and paste one of your
messages in this thread, for example, that's a reasonable sample.

#include <stdlio.h>
#include <ctype.h>
#include <string.h> -- don't feel compelled to use this

struct Node
{
char* wd;
int ct;
struct Node* left_child;
struct Node* right_child;
};
/*=========================*/
int main()
{
struct Node* tree = NULL;
char buff[1024]; /* line 16, a bonus line */

NB: This was not compiled
--------------- pseudo code -------------
open the file

loop
read a line -- perhaps gets()
if done exit the loop
isolate a word -- a function you write perhaps: char* isolate(char*
line);
add the word to the tree -- a function you write. perhaps: void
add(Node* root, char* word);

Post your attempt and explain which parts of it you're having
difficulty with, and why.

Don't worry about writing the whole program. I can see that it might sound
frightening, which is why I gave the help I did. Write the next few lines of
code and post *that*. If you post code you will almost certainly get more
help. If you can't or won't do that, your chances of getting further help
here are about zero.

That's because there is no such file or directory. C doesn't define such a
header, so there is no guarantee that any implementation will provide it,
nor that it will mean any particular thing if it /is/ provided.
void main()

main returns int. Always.

When you've learned that, and learned not to use gets(), you'll be ready to
ask some more questions.

I think your biggest mistake is trying to learn C from an inferior book. My
best guess is Herbert Schildt - your program seems to be full of his kind
of nonsense.

#include<string.h>
#include<conio.h>

conio is not part of standard C. Take this out and a bunch of errors will
crop up where you have used stuff from conio.The ones I saw were probably
nice, but not really needed. clrscr() is a prettifier, eliminate it.
getch() can be replaced by something from stdio, probably by getchar().
Take this stuff out until you see no more errors caused by rewmoval of the
conio header. Then fix what comes next or post a new version of your code.

It would have been better if you had got some of it working before doing all
that typing. But what's done is done.

That's an implementation-specific header. If you don't have it, there's
not much you can do. There are some similar things like ncurses that
are more commonly found, but are still non-standard from the standpoint
of this group.
clrscr();

Get rid of this, you don't need to clear the screen.


Get rid of all instances of this. You probably don't need a "pause
until continue signal", if you really can justify it we can offer some
standard replacements. It's generally the sign of a newbie to have
those.
printf("\n\t\t| Press your choise (l,s,q)\t|");
ch = getche();
switch(ch)

This is trickier. The best idea is to not use a one-key approach to
menus. Read a line of input into a string with fgets() or get the first
char with getchar() and discard the rest.

ignore the warning. gets is not bulletproof but this is just a student
program.
/tmp/ccSZ3XYi.o(.text+0xa2): In function `showMenu':
: undefined reference to `clrscr'

Take it out. You don't need it.
/tmp/ccSZ3XYi.o(.text+0x137): In function `showMenu':
: undefined reference to `getche'

This will be hard to resolve. Put in some way to proceed without solving the
problem. There is a lot of work ahead that is much more important than
getting this right. Replace it with getchar(), for now.
/tmp/ccSZ3XYi.o(.text+0x350): In function `createBinaryTree':
: undefined reference to `delay'

Take it out. Do you *really* need that? If you do someone can suggest a
workaround.

: undefined reference to `delay'

Same thing repeated n times, same cure. Now you may be getting close to
seeing your first *real* error.

ok so i made some changes and i got this
#include<string.h>
#include<stdio.h>
#include<stdlib.h>
#include<string.h>

No implementation-defined headers, good.

Pay attention to those errors. Don't call gets(); it's standard, but
dangerous. See question 12.23 in the comp.lang.c FAQ
<http://c-faq.com/>.

The clrscr(), getche(), and delay() functions are non-standard, and
you don't really need any of them.

Had you bothered to read what I took the good time and trouble to post,
you'd have seen that things like clrscr are non-standard and
(apparently) unavailable to you. I don't know what delay() is either,
but what do you need it for? Get rid of the non-standard crap.
