What are programming languages?
As you know, using a computer is the simplest and most transparent thing there is. You turn it on and that’s it. You should not worry at all about technical aspects such as hardware or how the programs you use daily are developed and designed. Programming Languages For Beginners programming language definition
This has been the case for years, and it is totally acceptable for it to be this way. Because what underlies an application’s windows and dialog boxes should never interfere with the productivity of the user of the software.
This is the responsibility of computer engineers and developers. Programming Languages For Beginners
However, it is never too much to learn something new, since in this way you will be able to better understand how a computer works or what its functions are , and how it interacts with us through software.
With this you gain in productivity and efficiency, and why not, you get that something else that differentiates us from others, and that translates into a better economic position. Programming Languages For Beginners programming language definition
That is why in this article you will find abundant information about programming languages and their evolution over the years. programming language definition
Everything you see as soon as you press the power button on your computer is not magic, it is technology.
The operating system, its applications, and the smaller parts such as dialog boxes, menus, windows, and buttons have their birth in programming languages. Programming Languages For Beginners programming language definition
A programming language is basically a computer program with the ability to create source code through a series of syntactic and semantic rules. These are made up of words, numbers, a set of symbols and expressions.
This source code, once compiled, will become a program or software and can be executed on your computer without the need for you to carry out any other steps. programming language definition
A little less technically, programming could be defined as the set of consecutive and ordered instructions that lead the computer to perform a specific task. What is done through any of the computer languages that exist.
It might seem that this definition is a bit fair. And it’s true, programming and programming languages are much more complex than that. Programming Languages For Beginners programming language definition
That is why later in this article we will delve deeper into these topics, which are fascinating. Read it to the end, you will see that you will be surprised by everything that programming and its languages cover!

What are programming languages for?
Still, for better or for worse, computers are not capable of making their own decisions.
The artificial intelligence is not sufficiently developed to make it happen. In other words, for a device to fulfill its task, it must be programmed. Programming Languages For Beginners
This will surely lead you to the following questions: How are these devices programmed?
The answer to this is through a programming language. But what is a programming language? What is a programming language for?
Here the answer is a bit complicated, but we hope that with the following lines you can clarify the picture a bit.
Computers at this point, although they are devices that can do countless tasks, the truth is that if you don’t tell it what to do, it won’t do anything. Programming Languages For Beginners
For a computer or device to carry out a task for which it is not programmed, it needs to be instructed to do so. This you must do through logical instructions.
In other words, the main function of a programming language is to solve the problem, which you will have to do in the form of algorithms. Programming Languages For Beginners
When you write code, compile, and so on to control device behavior, you get the computer to do what you want.
The end result of the task of programming , or writing that set of commands, is called a program, software, or application. Programming Languages For Beginners types of computer languages
What is programming for?
The answer to this question may be simple, but it is the most accurate.
Programming is used for everything you propose. In these times where computers and electronic devices are present in every moment of life, programming is essential.
This does not mean that in order to operate a device you have to know how to program. What he means is that programming today can be a very profitable activity. Programming Languages For Beginners
In this sense, programming can offer specific solutions to particular needs.
This means that if you learn to program any of the types of general-purpose language that exist today, you can give that solution to whoever needs it in the form of software, and charge for it. Programming Languages For Beginners
This can be applied to any of the commercial and industrial activities. All economic activity requires software to automate processes, management computing or web development solutions, such as web applications, among many other scenarios.
Software development is one of the most suitable careers for the times to come.
In this sense, in the near future more and more actors will be required who know how to operate in this field, especially due to the incessant deployment of technology that you can already see around you every day.
Elements of a programming language
Although each programming language has its own characteristics, the truth is that most share functions or semantic rules. That is why some languages are alike, even if the result is different. Programming Languages For Beginners
In the list that you have available in the lines below, we will show you the main elements of a programming language that are necessary for software development. programming language examples v
- Data types: This is how the data with which a programming language can work is called. According to its implementation and use, the following are common:
- Integer: Type used to represent whole numbers.
- Real: Type used to represent numbers with a decimal point.
- String: Type used to represent text data.
- Reserved words: This expression refers to the words typical of the syntax of a certain programming language. These are used to create instructions and command sequences. It should be noted that these types of words cannot be used to name or create new variables.
- Operators: These operators are used for the purpose of creating instructions through mathematical calculations, comparisons or logical operations. Operators are basically divided into three types:
- Arithmetic operators
- Addition and subtraction: + and –
- Product and division: * and /
- Exponentiation: ^
- Relational operators
- Minor: <
- Less than or equal: <=
- Greater than or equal:> =
- Equal: ==
- Other: <>
- Logical operators
- Y: AND
- OR: OR
- NO: NOT
- exclusive: XOR
- Arithmetic operators
- Constants and variables: Both types must be defined by an identifier. If not, you will not be able to reference them during the execution of the program. programming language examples
- Constants are basically data classes that cannot change when the written program is running.
- On the contrary, variables are data that can change during the execution of the application.
- Flow control structures : Flow structures can be divided according to the function they fulfill.
- FOR … NEXT: This structure aims to make a block of instructions repeat a predetermined number of times.
- IF … THEN … ELSE: Through logical comparison or other mechanisms, these flow structures are capable of executing one or more instructions. programming language examples
- Functions: Functions are basically a form of variables . They can be user-defined or belong to the language. They work as follows. When called, they execute a block of code or subroutine, simplifying the code of the written program. This is done to be able to be used more easily in all the occasions in which it is needed in the execution of the program. Programming Languages For Beginners programming language examples
- Comments: Comments are nothing more than text that you will use to comment on some part of the code. These comments will obviously not be executed, as they are only used to keep track of the code.
Types of programming languages
Programming languages are the basis with which all the applications that you use every day for your computing tasks are built. programming language examples
From the computer operating system to your favorite text editor, to the web pages you visit every day, they are all born from a programming language.
If you want to know more about the types of computer languages, in the following lines you will find excellent information. types of computer languages
The machine language , also called machine code is a coding system designed to be recognized and executed directly by a micro programmable circuit. programming language examples v
These devices can be the microprocessor of a computer or microcontrollers in numerical control machines, for example.
Basically, this machine language is composed of a set of instructions that determine the behavior of a machinery or controller. programming language examples
A machine language program is a string of these instructions plus the data on which it will return the results.
However, the machine language is completely expressed in binary code, that is 1 and 0, and therefore very complex to implement. In order for humans to interact with this code, it must be translated.
To solve this problem, and to make the life of the programmer easier, the assembly language was developed.
Assembly language made it possible to translate these long numerical strings into words like “Add”, “Sub”, “Mul” and “Call”, which operated directly at the hardware level. types of computer languages
These terms were later called “Instructions”.
Assembly Language and Assembly Language for translation to the Castilian, is a programming language for all types of processors and controllers. types of computer languages
This language is capable of interpreting and manipulating binary machine codes through a symbolic representation and making them “more accessible” to programmers. types of computer languages programming language examples
Assembly language was used at the dawn of computer science, when more powerful and flexible languages had not yet been developed. programming language examples types of computer languages
However, it is still used academically and when it is necessary to have direct access to hardware, as in the case of operating systems and device drivers for printers, scanners and other types of peripherals. types of computer languages
It should be noted that assembly language is considered a low-level language.
It must be in memory while the program is running, the program needs to be translated every time it is run. Each instruction is being translated as it is being executed, with that the program ends up being slower.
Examples of this are Access, DBase and other applications of this type.
It does not need to be in memory while the program is running, as it is translated entirely once only, making its execution very fast.
Examples of this type of apps are Delphi, Clipper, Pascal and C, among others.

Learn to program
The application program is one of the most profitable professions that are in those days. Therefore, it is not surprising that more and more people are inclining their study preferences for this area.
However, it can be a difficult task to learn, as the road ahead is arduous and long. Programming is not something that can be learned in a few days or weeks.
Learning to write your own applications and also do it for external clients like a professional can take you a few years. However, this is not to say that programming is a profession for only a few.
With patience and dedication you can achieve success on the path you have undertaken, it is only a matter of persevering and studying.
But for this to work, you must take into account some considerations, which has to do more with what you need to learn to program.
In this sense, first of all you must be clear about what you want to learn to program.
In other words, if you want to design management applications, web programming or video games, the first step in the learning chain is undoubtedly the type of programming language you need to learn.
We all know that in the field of programming, the offer of software to create applications is vast, and above all very changing.
This is mainly due to the fact that these applications and languages can most of the time be used interchangeably for different types of applications.
In this sense, there is nothing worse for the person who wants to program than the proliferation of offers that lead him to a dead end when it comes to sitting down and learning.
This means that the user who is just starting to program needs to focus on only one aspect, and avoid dispersing into other languages and forms. programming language examples
As you have noticed, learning to program right from the beginning is a complicated task, but not impossible.
In order to be of help in this aspect, from this point on we are going to know some of the most interesting ways to learn to program.
The first option you have available to learn is self-taught, that is, learn to program on your own. This is possible as long as you have a solid foundation in math, determination, and a good library or reference base.
Fortunately, on the Internet you can find material to learn programming totally free, including courses, tutorials and books in PDF format.
All this will be of great help, especially if you do not have enough budget to buy the necessary books.
In this sense, the technical literature that you need to get must cover from the fundamentals of language.
For this, the best way to find all these materials are forums or websites dedicated to programming languages.
You can also draw on the wisdom of friends, family and acquaintances, as you should never discount good advice.
The self-taught method may include, among other study tools, the possibility of practicing on programming languages.
This means that you should start programming from the reference materials directly on the programming language you want to learn. programming language definition
Another way to learn programming is to enroll in an introductory course on the subject in person.
From there, combine the knowledge acquired in said course with self-taught studies.
This will allow you to learn to program at your own pace and needs, starting from a solid foundation.
The only condition for this to work is that the course you take guarantees good content and that it is up-to-date, otherwise you will only be wasting your time.
Finally, we must not rule out the possibility of obtaining formal studies in programming since this is the option that also offers you more benefits.
Of course, this path is the one that will open the most doors for you in the future!
Sure, the road is more winding, but the benefits of earning a computer science degree are better.
If you are interested in knowing what it is to program in computer science , below these lines you will find information about the different approaches to learning programming languages that exist.
This could be taken as the first step to start the path to good learning.
