How to create a computer program

Updated: 02/04/2024 by Computer Hope

Many factors that dictate how a program is developed, including its type, its features and capabilities, and whether it's a desktop or online program. These factors also depend on the language used to write the program's code. For these reasons, it's not possible for Computer Hope to provide exact, step-by-step instructions for creating a program. Instead, we provide guidelines and recommendations to help you determine the best way to get started and develop your program.

Computer programming

Anyone interested in developing software, such as a program or application, game, or online service, must start by learning a programming language. There are hundreds of programming languages, and creating a new program requires more training and time than one page can provide. Therefore, this page is a general overview to help point you in the right direction to get started. An important beginning step is to have a plan for what program you want to develop. For instance, a plan includes the purpose of the program, game, or service, and the features you want to include. Be thinking of what your plan is as you continue reading.

Picking the language

As we noted above, there are many different programming languages. The programming language is what decides the rules and structure (syntax) of your program. Deciding which language to learn can be challenging by itself. Creating a program with many features and functions often requires you to be fairly proficient in one or more programming languages.

That said, basic understanding of the concepts of almost any programming language helps get you started. Our listing of programming languages includes examples of the various types of software each language can create. Here are a few of our recommendations.

Deciding on your programming language depends on what type of program or script you want to create. For example, Java and Visual Basic are popular because both are a good way to learn programming fundamentals. Other popular languages include C, C++, and C#, which create games, applications, drivers, operating systems, and many of the programs.

If you are interested in developing scripts and programs, like online forums, search engines, and services, Perl, PHP (PHP: Hypertext Preprocessor), and Python are all popular choices, in addition to HTML (hypertext markup language).

Deciding on an editor

An editor is any program that lets you write computer code. They range from simple, like a basic text editor, to advanced software, such as Adobe Dreamweaver, Eclipse, JDeveloper, or Microsoft Visual Studio. Fortunately, any program can be written in a text editor, which means you can get started for free. As you get more comfortable with a programming language, using a more advanced editor is recommended, as it can make coding and testing the code more efficient.

For Windows users, we suggest an editor such as Notepad ++ because it is free and supports syntax highlighting. If you're on a Mac, use the free editor named TextEdit. Additionally, visual programming languages, like Visual Basic, include the editor and compiler in the same tool used to create programs.


Most computer programming languages are high-level programming languages, meaning they are easy for you to understand, but impossible for a computer to understand. For the computer to "read" your program, it must be compiled or have an interpreter. Your choice of programming language is the deciding factor on whether or not you need a third-party program to compile or interpret it.

For example, Eclipse is an interpreter that takes a program written in Java and "translates" it to code understood by a computer. Other languages, like Perl, are interpreted, meaning they do not need to be compiled. These languages only require that they are installed on the computer or the server that is running the script.

Learning the language

After deciding on a programming language, editor, and compiler, you are ready to program. For most users, the easiest way to start is with the famous "Hello World!" program. After running your program that prints "Hello World!" to the screen, the next step is to learn the language's syntax. To do so, you must understand the following concepts:

When you have questions, an Internet search can answer most of them. Books written for your programming language or programming courses are great ways to develop your skills further, too.
