COMPUTER PROGRAMMING 101
I truly cannot fathom a life without a computer, yet I know many people in their 50’s who are very intimidated by the computer. Some of them are actually afraid to touch it. This is because when they were in grade school and high school, computers were not available the way they are now. At that time “computer” meant a machine that filled a good size room, a monolith that none of them ever dreamed would some day fit on the top of a table, or in their lap. While many of the 50+ crowd have come into the 21st century and now own and operate a home computer, or work with one on the job, there are still many out there who are wary.

There is really no reason anyone should feel intimidated, especially with all of the computer instruction courses available. Many of these lessons can be obtained on CD or by download to your computer, and will take you step by step through tutorials on how to use your computer. There are others that will teach you how you can program your computer to do just about anything you wish.

Most home PC users are interested in the basics: letter writing, game playing, shopping, news etc., and most of them would like to be able to use the programs that are downloaded on their computers. These include writing programs, Photo applications, printer applications, computer upkeep, and so much more.

This is where you will need to begin, by learning all you can about how to use your PC, you will be taking the first step in opening up a new and vital world for yourself. You will then be able to go on to other applications. Computer programming is a must for anyone who wishes to get a job using a computer, and is a big help for those who just want to get connected.

WHAT IS COMPUTER PROGRAMMING AND WHY SHOULD I CARE?
If you have a personal computer, you have probably already used the software for word processing, to solve problems, or set up spreadsheets. We thought maybe you would be curious about how programmers write the software you have used.

A Program– is a set of instructions that tell the computer, step by step, how to perform the tasks you command it to, and produce the results you have in mind. There are three great reasons for learning computer programming:

• Programming will help you understand computers. The computer is a tool, and if you learn how to write simple programs, you will also learn how the computer works.
• After writing a few simple programs your confidence level will increase. There is a personal satisfaction in creating a program that will solve a problem.
• Learning basic programming will show you whether you like programming and possess an analytical mind, which is needed in computer programming. If it should become apparent that programming is not your cup of tea, you will find that an understanding of the programming process will increase your knowledge of the computer and your appreciation for the tasks that programmers and computers can perform.

Computer programming is a set of rules that tell a computer what operations the user needs it to perform, this is a programming language. There are many computer languages and they are listed later in this ebook.

What a Programmer Does
The programmers job is generally to solve problems by formulating instructions for the computer. The programmer will prepare the instructions for the program and run those instructions on a computer to test the new program to make sure it is working properly. If they find the program does not give the correct outcome, they must make corrections and then test the program again. The programmer will also write a report on the program in the form of use instructions.

A programmer could probably perform this programming by themselves, but they usually interact with others. If a program is part of a system containing several programs, the programmer will work with other programmers to assure that all the programs will work together. A programmer may also have coordination meetings with managers, system analysts, and computer users.

Developing a program means using steps as you would in any problem solving task. These are the steps in the programming process:
