What makes high-level programming languages ​​secure

High-level programming languages ​​that you should learn?

If you want to find out which programming language to learn? 6 Easiest Programming Languages ​​for Beginners to Learn 6 Easiest Programming Languages ​​for Beginners to Learn In programming, you learn to find the right language, as well as the edification process. Here are the six easiest programming languages ​​for beginners. Read More People talk about high and low level programming languages ​​all the time.

But what exactly does that mean? And what does it mean to learn to write code? Let's start with the definitions of each and let's move on.

“Higher” and “Lower Level” programming languages

In this article I'm going to talk about “high” and “low” language skills. But there is No specific qualification criteria for either. That's why I'm going to talk about “higher” and “lower” levels as well.

Just keep in mind that this largely depends on your perspective. If you are a C programmer, Java can appear at a high level. If you're used to Ruby, Java seems like a simple language.

Machine code and low-level languages

Whether a language is viewed as high-level or low-level (or somewhere in the middle) is all about abstraction. Machine code has no abstraction - it contains the individual instructions that are passed to a computer. And since machines only work with numbers, they are represented in binary (although sometimes they are written in decimal or hexadecimal).

Here is an example of machine code (via Wikipedia):

Processes must be specified precisely in the machine code. For example, when information needs to be retrieved from memory, the machine code needs to tell the computer where it is in order to find it.

Writing directly into machine code is possible, but very difficult.

Add low-level programming languages a bit of abstraction from the machine code. This abstraction hides certain machine code instructions behind declarations that are easier for humans to read. Assembly languages ​​are the lowest languages ​​besides machine code.

In machine code you might write something like “10110000 01100001” - but an assembly language could make that easier “MOV AL, 61h". There is still one nearly One-to-one correspondence between what is written in the assembly language and the instructions that are passed to the machine.

If you switch to more popular programming languages, you will come across something like C. Features of C programming that make it unique (and better). Features of C programming that make it unique (and make it better). The programming language C is the mother of all modern programming languages. Almost every language today contains several functions that first appeared in the C language. Continue reading . Assembly language may not be cheap, but there is still a strong correspondence between what is written in C and the machine code. Most of the operations written in C can be performed with a small number of machine code instructions.

High level programming languages

Just like the subordinate languages, higher levels cover a wide range of abstraction. Some, like Java (which one could argue is actually a Medium level Programming language), you still give a lot of control over how the computer manages memory and data.

Others, like Ruby and Python, are very abstract. They give you less access to these child functions, but the syntax is much easier to read and write. You can group things into classes that inherit properties so you only have to declare them once.

Variables, objects, routines and loops are all important components of high-level languages. These and other concepts will help you tell the machine to do many things with short, succinct statements.

When an assembly language has near one-to-one correspondence between its instructions and the machine code instructions, a higher-level language may be able to transmit Dozens of commands with a single line of code.

It is important to note that “high-level programming languages” may include anything more abstract than an assembly language. It depends on who is discussing the topic. So if you are talking or reading about languages, make sure you are on the same page.

Should you study a low or high language?

This is certainly a common question among new and aspiring programmers. Are high or low level programming languages ​​better? As with many programming questions, the question of high level programming languages ​​is not that straightforward compared to simple programming languages.

Have both types of languages important advantages. Low-level languages ​​generally run very quickly because they require little computer interpretation. Why are some programming languages ​​faster than others? Why are some programming languages ​​faster than others? There are numerous programming languages. They all have individual quirks that are used for different things. But what makes one programming language faster than another? Continue reading . They give programmers a lot of control over data storage, storage, and retrieval.

However, high-level languages ​​are more intuitively understandable and allow programmers to write code much more efficiently. These languages ​​are also considered to be "safer," there are more safeguards preventing coders from issuing poorly written commands that could cause harm. However, they don't give programmers as much control over low-level processes.

To keep this in mind, here is a selection of popular languages ​​on a scale from low to high:

  • C.
  • C ++
  • Java
  • C #
  • Pearl
  • lisp
  • JavaScript
  • python
  • ruby
  • SQL

Of course, this is partly subjective. And it only includes one tiny cross section of the available languages.

But it should give you an idea of ​​where the languages ​​you care about fall on the scales.

What do you want to do?

When deciding what to learn should be your first question what you want to program.

If you want to write operating systems, kernels, or something that needs to run at the highest possible speed, a lower language might be a good choice. Many of Windows, OS X, and Linux are written in C and C-derived languages ​​such as C ++ and Objective-C.

Many modern apps are written in high-level or even domain-specific languages. Python and Ruby are particularly popular in web apps.

This article provides a checklist of questions the programmer should ask in order to choose the language. Read More Languages ​​like Swift, C #, JavaScript, and SQL all have their own strengths and weaknesses.

Consider studying both

I recently read a thread on this question on a programming forum and came across an interesting suggestion: learn both at the same time. You will get a deeper understanding of the types of abstractions that make the higher level language more efficient.

Of course, it is not easy to learn two languages ​​at the same time. 7 Useful Tricks For Learning A New Programming Language 7 Useful Tricks For Learning A New Programming Language It's okay to be overwhelmed while learning code. You will likely forget about things as quickly as you learn them. These tips will help you retain all of this new information better. Read More Choosing two similar languages ​​can also be helpful.

Again, let's go back to the point I made earlier: choose a language based on what you want to build. Find out what languages ​​people use in your field. Then use this information to select and study a high-level and high-level language.

You will soon see the parallels and get a deeper understanding of how programming works.

Focus on goals, not means

There are many criteria by which you can choose a programming language. High vs. low level is one of them. However, in almost all cases, you should use the criteria that you should be using what you want to program.

Your project could benefit from using simple language. Or it could be much more efficient at a higher level. The key is choosing the right tool for the job. Focus on your goal and you will always choose the right language.
