Design Your First Computer Program


Designing First Computer Program

When building an application, you should first have a strong understanding of the purpose of the program and what it will create. You must have the detailed specifications needed to begin thinking about what you should do.

For example, if you are designing a website program for handling requests, you must understand the pages that it will manage, the purposes of each page, and the intermediate operations throughout the requests, including linking to a database and accessing or writing to it. All of this needs to be understood beforehand.

You must manage your thinking on forms, knowing all these facts and functions in the application you are constructing. This is done using flow calculations or charts. This will help you significantly to monitor all the processes in the request and design the program accordingly. If you overlook this, you may find difficulties when creating the actual program, especially if the program is complicated.

After you have understood how the businesses may flow and drawn the flow information, you can apply what you prepared from the programming language you select. This step is also called programming because you are writing code that represents the functions you prepared in the earlier step.

Once you are done, you can test and run your application. But wait, many problems may appear. This is considered the final step in the programming life cycle, which is called troubleshooting, and you must correct any issues that arise during testing.

Many tools are available for testing and running the program, which may ease your work. Do not forget that there is a distinction between the libraries that create the language and the run-time environment you use.

For example, Java programming has the so-called JDK, which offers the core libraries making up the language but has a separate run-time environment that is a separate program for running and delivery. You may execute your program from DOS, but these tools greatly assist you. The Java language, for example, has a runtime system called NetBeans, which provides a run-time environment and has rich tools for dealing with applications.
