At this stage, you have the basics required to be able to create your own computer program. But in order to be able to code effectively, you need specific tools and software. This is what we will see in this section and Cheap Resume Writing Services .
tool # 1: programming language
The first tool you need to program is obvious: it is the programming language. To understand what it is, you have to understand the algorithm.
You will remember that the description language used to write the
The result of the analysis of a problem is called an algorithm . When we translate this algorithm into a language, we are coding.
Suddenly, a programming language is an intermediate communication language between humans and the machine, which makes it possible to write in a language understandable by the machine, the set of operations that the computer must perform .
There are a multitude of languages depending on the programming paradigm and the category of problem you want to solve. To better choose from this plethora of languages, you must ask yourself what you want to do. What kind of computer program do you want to create? Depending on the answer you are going to provide, you should adapt your choice of language.
Here are some examples of languages classified according to their programming paradigm:
You can see that there are some languages that come back on another line. Indeed, there are languages that support multiple paradigms, as we mentioned in the programming paradigm section. This will allow you to make all kinds of programs in the same language. In Big Data and on all the issues that concern data processing in general, the 03 most used languages are: Java, Scala and Python.
Tool # 2: Integrated Development Environment (IDE)
After the programming language, you need another fundamental tool: the integrated development environment, for short IDE ( Integrated Development Environment ).
The IDE is a platform that brings together in a single graphical interface the tools you need for the entire development lifecycle of your software and buy term paper online. You will find inside the following elements:
a text editor: to write your program in the language you have chosen
a debugger: a tool to examine bugs that occur in your program
autocompletion: which automatically offers language instructions so that you don't have to type them in completely every time.
A build tool: to compile your application and generate its deployable package
a versioning tool like Git for managing versions of your code and working with other team members
Using an IDE is not mandatory for developing apps, but I highly recommend using it because they will make your job easier. There are several IDEs and each of them is often specific to one or more languages:
For Java and Scala: Eclipse, IntelliJ, Netbeans, etc. ;
For PHP: Netbeans, Zend Studio, etc. ;
For .Net languages: Visual Studio;
For Python: Jupyter
The life cycle of a computer program
You are almost at the end of this guide. Finally, it is essential that you know how a computer program is made. In other words, the different stages that go into the development of software from its conception on a blank sheet to its deployment on a computer by users. This is formally called the life cycle of the computer program . We talked about this a bit in the previous sections, but it's important to get started to understand these different steps .
Before getting into the actual life cycle, it is important that you know that there are several types of programs depending on their usefulness. This type depends in part on the medium on which you want to deploy it. For example, when you develop an application that will run on the Internet, we talk about a website or a web application and buy speech online. For an application for local use on a PC, we speak of a desktop application . For an application for local use on a telephone, we speak of a mobile app . If it is an application that serves resources to other applications, we speak of the backend . If, on the contrary, these are applications that will request a resource, we are talking about client or client application . If it is an intermediary application between a client and a backend, we speak of middleware . There are also programs intended for use by other applications by incorporating the latter. It is precisely the API of the libraries or extensions .
The lifecycle may vary slightly depending on the type of application, but overall here are the phases of developing a computer program:
Implementation: this is the phase of writing the code. It is during this phase that we apply all the bases that you saw previously.
Debugging: this is a stage in which you will undoubtedly be spending a lot of time. This is because bugs can still arise, even with those who are very experienced. This is to correct code errors. To do this, you need to identify where the error came from, then correct it.
Interpretation: the role of interpretation is similar to that of compilation. Its purpose is to interpret the code in machine language, because there are languages that are interpreted like Python or VBA, and there are others that are compiled. Unlike a compiler, an interpreter reads the lines of code one by one.
Good practice in computer programming
We will end this comprehensive guide with a few notes on good programming practices and essay writing. To program well, here are some tips we can give you:
Be curious, don't take anything for granted, because computer programs are first and foremost the result of human thought. This means that the same program can be developed differently depending on the developers. A spirit of curiosity is essential to copy the best algorithmic strategies and improve your programs.
Stay abreast of new trends in the field and learn continuously, because in IT, things are changing enormously. It is said that on average, technologies evolve over a 6 month cycle. You will therefore need to be on constant watch to be on top.
Find and adopt a style: there are a thousand and one ways to develop a computer program. It is not worth trying to master all these processes. What you need to do is master the process that matches your personality and your way of seeing things, then correct it as you progress in your skills.
