Hash Table project

Basically a Hash table project to be implemented in C++, not complex code, easy to maintain and to extend.

The Hash table implementation is slightly different from normal Hash Tables but it should not be too

complex to code.

I may have to port the code to a Kernel Driver model.

## Deliverables

1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.

2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request.

3) Complete ownership and distribution copyrights to all work purchased.

ok here we go.

This is a personal project that I need to acomplish within a few days.

I need to implement a solution to a

query project using Hash tables. I want the

code to be done in C++. I don't want complex

code, easy to maintain and perhaps to


The project is as follows...

I want to maintain 2 Hash tables which

will be pointing to the same object

consisting of the following entries:


a 16-byte value

a Pointer to an object

a Next pointer

a Next Pointer


The Pointer to an object I want to

use it in such a way that sometimes

that object may be an Int or sometimes

a 16-byte value. I think overloading it

will work here.

The Next pointer is added twice because

we will be having 2 Hash tables pointing

to the same object so we may have

to use these 2 pointers.

Each entry in the Hash table must be of

this type and it must be done as a link

list, meaning it must grow as demands

requires it.

The size of each of the 2 Hash tables

is of 256 entries each. So We will

have 2 arrays of 256 entries each.

The reason I thought of having 2 Hash

tables pointing to the same object is

that sometimes I need to do a query

using an 8-bit value and sometimes

I am using an integer value, which in

this case I will have to just use the

first 8 bits of the value and discard

the rest.

The project should be able to

distinguish between a 8-bit value and

an integer so that it queries the

appropriate table and then it does

a match from there.

The project must be able to do the

following actions

1.- Add a relation between an 8bit

value and a 32 bit value.

This will be the function that

adds data to the tables.

Using the 8bit value, I get a

location in the table, it then

adds the 8 bit value and the

32 bit value and sets the

appropriate links in the Next


It will also do the same for the

second table where we index by the

integer value.

We should end up with 2 entries

one for each table..

2.- Query the Tables whenever we

pass a 8-bit value, return

true if we found a match

whenever we use the 8-bit value

and the integer value.

here we use the 8bit value as

an index to figure out the location

and then we use it to find a match

along with the int value in the

object structure or class.

query_by_8bit(8bit value, int value)

3.- Query the Tables whenever we

pass an integer value, similar

as above, but querying by the int


query_by_integer(8bit value,

int value)

4.- Delete an existing object

This fnction searches the objects

by using the 8bit value as index

and as soon it finds a match

it deletes the link.

DeleteValue(8bit value,

int value)

5.- Edit an existing object when we

want to change a old integer field

with a new one.

changeIntegerValue(8bit value,

int newvalue,

int oldvalue)

## Platform

Windows NT 4.0

I am using Visual Studio 6.0

SDK/DDK etc.

## Deadline information

Well, in all fairness I need the

project within a week, meaning by Nov 11. I am hoping this is not too complicated of a project for some C++ gurus.
