In this technological age, programming is becoming a very sought-after field. However, there is a method to the process that begins with problem solving followed by program implementation. This article will explore the steps in implementing a program and what each step entails.
What are the steps in implementing a program
The steps used in implementing a program are:
- Create the source code;
- Translate or link the source code;
- Execute or run the program; and
- Maintain the program.
Creating source code
In writing computer programs, the first step is to prepare your source code. Every computer program has its own language structure. Codes may be written in text editors; however, we typically use programs specifically designed for writing the language of our choice. For instance, we may use the Ezy Pascal compiler or this online editor to write Pascal programs. Or, if you are writing in the C++ or C programing language used for the Caribbean Advanced Proficiency Examination, you may use the Dev C++ software. The code is saved in the extension for that particular language, e.g., .pas for Pascal and .c for the C programming language.
Before writing an actual computer program, it is important first to create an algorithm (the blueprint) of the program and use a trace table for correctness. Visit our article to learn more about what an algorithm is.
How to translate or link the source code
Once you have created your source code, the next stage entails linking or translating the source code. For this, we often use a compiler. Compilers convert the program code to machine language (1s and 0s) so that the computer will understand.
It should be noted that today compilers are also used as code editors instead of text editors. Once the code is translated, executing or running the program is next.
If you are new to programming in Pascal, then you should visit our article on what Pascal is to learn more about the language’s basic syntax. Additionally, our article on Pascal programming operators is very important to help you to learn more about the operators available in pascal and their uses.
Run or execute the program
When we execute a computer program, the computer takes the instructions written in code and completes all of the instructions. If the instructions do not bring about the expected results, you would then need to debug the program. This brings us to the last stage, called program maintenance.
Maintain the Program
Maintaining the program is a very important step in implementing a program. Once they are created, all programs must be maintained to ensure the best experience for end users. Maintainance entails all of the following processes:
- Identifying and correcting errors;
- Adding functionalities; and
- Remove unnecessary sections.
Identifying and correcting errors (Debugging)
Normally even programs that have been sold to end users can encounter errors when something unexpected is done. Today, Most programs are set up to automatically generate error reports that are sent back to the programmers to allow for improvements. These errors are called bugs. The act of correcting errors is called debugging.
Adding Functionalities
Software programs, once they have been created, do not remain dormant. Quite often, during the process of using software, you may receive notice of updates to the program that needs to be installed. These may correct bugs or add new functionalities to the program. Adding functionalities helps programmers stay ahead of the competition and meet their users’ changing needs.
Removing unnecessary sections
Refining your software to suit the end user may sometimes involve removing some sections, particularly if it is rarely used but adversely affect those sections that are of more interest to the user.
