DESIGN AND IMPLEMENTATION OF A COMMAND DRIVEN INTERFACE PROGRAM FOR NUMBER BASE CONVERSION USING VISUAL BASIC

ABSTRACT

This project work is carried out to identify and discuss the need for the use of a command in number base conversion which is known or called command driven interface program; also the deals of all models of different type of number base conversion.

The advent of the computer has extended businesses and organization the capabilities for its achievement in our today livings.  Just as we are about to see in these book with respect to its effectiveness and accuracy in number base conversion using a command driven interface.

The manual way of converting a number from one base to another appears to be so difficult for our days students especially when dealing with a large number, but these study is set aside to enhance efficiency and mark the work easier for our student.

THE ORGANISATION OF WORK

These study is being organize into six chapters.

Chapter one deals with the introduction of the proposed study.  Under this chapter, problem of study is introduced, the purpose of the study, aims and objectives also the scope or delimitation of study, assumptions including the terms of used definition.

For chapter two, it reviews the literature reviews related to the research’s area of study.  Chapter three, deals with the description and analysis of existing system.  These chapter starts with the facts finding, method used also the objective of the existing system. The problems of existing system and justification for new system.

Chapter four highlights the designs of the new system.  This chapter comprises of output specification and design, the input specification and design.  File design, the procedure chart, system flow chart and system requirement.

Chapter five is talking about implementation, the program design, the program flow chart and pseudo codes.  It is also make up of the source program and test run.  Chapter six talked about the documentation, the chapter seven concludes the study.  It contains the recommendations and conclusions.  Thee chapter is broken into the following subheading, recommendation and conclusion and references.

1.0       INTRODUCTION

Computer And Computer Programs happened to become more and more of an essential part of our every day lives. This is because computers are everywhere, whirring and whizzing their electronic ways into cars, homes, offices, schools and business activities.

When this machine was first developed, the only people who could operate them were highly trained engineers and scientist to unscramble the genetic code, but these days almost everybody operates computers as a part of daily life activities. Of course many people may not necessary think about the fact that are operating computer as they make adjustment to their digital watches. This tells us that it is important to make computer as easy to make use as possible since so many people now happen to operate this machine that its use seem limitless.

Numbers are usually assign symbols by which ideas they represent are coded and the numbers of digits used to code number in any base is equal to the base, but the conversion of numbers from one base to another appear to be difficult with respect to time wasted in trying to calculate especially when dealing with large numbers, that makes its so boring by the time your thinking ability is involved.

The advent and the introduction of computer machine has brought an aid to help surmount these problems with the use of a given command.

A computer operator can not just start operating on a computer without having a little ideas of what he/she wants to carry out on the computer before a computer should carry out any structure given, you must apply a command before that task can be executed on.

It takes just a brief introduction of a command for a new user to become familiar with these computer, since it constitutes of a language in which the use user in communicates with the computer.

The interactions between the computer and the user is what we called a computer interface the term computer interface is meant to cover all aspect of these interaction not just the hardware.  The primary purpose of the computer interface is to enable full communication between the user and the computer system.

1.1    STATEMENT OF THE PROBLEMS

          Some given problems we have to know about in the aspect of a command driven interface are listed below:

1.           Can a given problem be programmed to convert number fro one base to another with the use of a command driven interface?

2.           can the introduction of the command driver interface in the aspect of number base conversion eliminate

1.2       THE PURPOSE OF THE STUDY

The study happens to be very important since its purpose and objectives of carrying research on these study and analysis are to:

i.        to design and develop a system that will be more effective in carrying out the operation of base conversion primarily.

ii.       to ascertain whether the existing system is adequate.

iii.          It will also highlight inadequacies, if any and determine ways through which application packages can minimize or eliminate the established problem.

1.3       SCOPE OF THE STUDY

Since different conversions exist in curriculum and test this study concentrates on command driven interface with respect to number base conversion.

The study is restricted to number base ten, base five, base six, base seven, base eight, base nine and base sixteen also a reserve conversion back to base ten.
