High-level programming languages are computer languages that allow you to give the computer high-level concepts. These algorithms, also known as high-level programming languages, are then compiled into machine-code. High-level programming language is hard for humans to understand, but computers can easily interpret and run it.
English is the basic form of high level languages. It can be combined with keywords (or special terms) to represent certain actions. The following high-level code tells the compiler to print “Hello World!” when it is executed.
print (“Hello World”);
You can see that the keywords print (), represent an action. This high-level code can be compiled and converted into machine code that the computer can execute.
Programming languages are necessary for desktop development and mobile app development , or any other solution you need to solve a business problem in the technology industry.
What are the advantages of high-level languages?
Programmers can write high-level programs in high-level languages, which is easier to understand than programming them in machine code. These high-level algorithms can be compiled into machine code that computers are able to execute. This simplifies programming as high-level language compilers inspect your high-level algorithms before compiling them. They warn you if they are missing or wrong.
High-level languages have a big advantage over lower-level languages. They use less memory space, but require less memory to run them. However, they take longer to write. While assembly language takes less time to program, it requires more memory to run the computer. They also have a limited range of capabilities and are more difficult to understand. Although high-level languages make programming easier, computers still have difficulty understanding complex code without having it compiled.
High-level languages can be classified by high-level concept algorithms because they are about communicating high-level concepts to the machine. The type of high-level programming language your program is in will depend on the high-level concept it uses.
What types of programming are available at high levels?
Let’s look at some of most popular high-level programming languages in the field.
1. Procedural language
This language uses high-level concepts such as loops and conditionals (if/then/else sentences) to allow programmers to create instructions that the computer will follow step by step. These instructions are known as procedures or functions. They heavily use brackets (), to distinguish different sections of code.
This language works best with data stored as variables such as buckets.
2. Programming language that is object-oriented
High-level programming languages allow programmers to use data stored in classes. For example, blueprints that provide instructions for creating objects (real-life things) are one example of such classes. You could, for example, have a blueprint to build a car. Each time you want to make a car you would use that class.
This programming language is high-level and heavily uses “dot syntax”. Variables/objects can be accessed by adding two periods to the variable name (car). wheels). Other high-level languages, such as Java and Python, use dots syntax.
3. Functional programming language
This high-level algorithm is focused on high-level concepts such as functions and recursion. It allows programmers to break down complex algorithms into smaller ones with instructions for the computer.
High-level programming languages use data stored in immutable variable (variables that cannot be changed after they are created). This makes it less complex because programmers don’t have to worry about code breaking up in other parts.
4. Declarative programming language
This high-level algorithm gives programmers instructions. Instead of giving specific instructions (like procedural language), they can simply say “do that when this happens.”
This high-level concept is achieved by programmers using high-level concepts such as conditionals (if/then sentences) and loops (“high-level instructions that execute high-level code instructions repeatedly”)
What does a programmer do with high-level programming languages?
High-level algorithms are broken down into smaller pieces called queries. Each query asks the computer to perform a specific action. A query might ask the computer to locate all persons over 18 from a list. This algorithm uses dot syntax and works with variables.
This allows you to quickly process large amounts of data. It breaks down complex algorithms into simpler steps, allowing the computer do multiple things at once.
High-level programming languages can be very different and offer high-level concepts which allow high-level programmers create high-level algorithms with high-level languages.
Real case scenarios as examples
Imagine you are looking to program graphics-intensive programs or games. It is recommended that you study a high level programming language that includes an Object-Oriented high–level concept algorithm and a procedural high-level instruction set. These languages allow the programmer to have more control over what happens on their computer.
You can process large quantities of data, such as photos, videos or other media, by learning a high level programming language that includes a Declarative high–level instruction set and a Functional high–level concept algorithm. This type of high-level programming language can handle all your data simultaneously without having to deal with many high-level instructions.
What should a beginner look for?
A beginner high-level programmer should learn a language that uses the Imperative high level concept algorithm. This allows you to have both high-level and low-level code within one high-level program.
Let’s say you are more interested in high-level programming languages. If this is the case, you should start with Java or Python because both languages are popular and widely used.
But what if you are interested in computer engineering? Or becoming a professional programer? C++ and Assembly programming are better than Java and Python for programmers.
This is it for this post. Low-level programming is not my focus; I am only providing information on high-level programming to help you avoid getting confused while learning high-level concepts. I appreciate you reading my blog.
