A Study on High-Level Computer Languages (2024)

A high-level language (HLL) is a programming language, such as C, FORTRAN, or Pascal, that allows a programmer to develop programmes that are independent of the type of machine they are running on. all these languages are classified as high-level because they are more comparable languages than machine languages.

High-Level Language (HLL):

A high-level language is more abstract from the computer than a low-level language, emphasizing the programming logic instead of the underlying hardware components such as memory addressing and register utilisation.

Assembly languages, on the other hand, are called low-level since they are quite similar to machine languages.

Machine-friendly language is used in low-level programming. Programmers use binary or assembly language to write code. Writing binary programmes is a difficult and time-consuming task. As a result, to make programming more user-friendly. English statements are used to write high-level language programmes.

Compilers/interpreters convert source code to machine language for high-level applications. We can convert source code written in a high-level language to a variety of machine languages. As a result, they are a machine-independent programming language.

Almost all programmes nowadays are written in a high-level programming language. Using high-level languages, we may create a wide range of applications. They’re used to make desktop apps, websites, system software, utility software, and a variety of other things.

Types of HLL

Computed and interpreted high-level languages are divided into two types based on their execution methodology.

Based on the programming paradigm, we can also divide high level languages into numerous groups.

Programming paradigms are a means of categorising programming languages based on their programming style and characteristics. Modularity, objects, interruptions or events, control flow, and so on are all characteristics that define a programming paradigm. A programming language might be a single paradigm or a multi-paradigm programming language.

Advantages:

• High-level languages are user-friendly to programmers. They’re simple to develop, debug, and keep up with.
• It gives machine languages a greater degree of abstraction.
• It is a machine-independent programming language.
• It is simple to learn.
• Errors are less likely to occur, and they are easier to locate and troubleshoot.
• Programming productivity improves when you use high-level programming.

Disadvantages:

• The time it takes to transform the source code to machine code is longer.
• In comparison to low-level programmes, high-level programmes are slower.
• They are often less memory efficient than low-level programmes.
• Direct communication with the hardware is not possible.

Important High-Level Computer Languages:

Java

Java’s popularity stems from its platform-independence feature, which allows it to operate on a variety of systems, including Macintosh, Windows, Unix, Linux, even Mainframe/mobile phones, as long as they have the JVM installed.

The Java Language’s Class Library and Java API are the most important parts to master. Despite the fact that Java only has 50 keywords, the Java API has thousands of classes and tens of thousands of methods that are utilised in programmes.

Python:

Python is a high-level interpreted computer language for general programming. In 1991, it was released.

Python was created with the goal of maximising code readability and minimising the use of whitespaces. Its main features include dynamic type, automated memory management, support for different programming paradigms (PO, Functional, Procedural), and a huge complete library of its own.

Swift:

Swift is a multi-paradigm, general-purpose compiled programming language created by Apple Inc. for iOS, macOS, and Cocoa frameworks. It makes use of the Objective C runtime library, which enables C and C++ to coexist in a same programme.

Kotlin:

Kotlin is a statically typed programming language that can be compiled to JS Source and runs on the JVM. The Android OS is fully supported by Google. One of Kotlin’s main aims is to compile as rapidly as Java. The key innovation of Kotlin’s latest release was code sharing between the JVM and JavaScript platforms.

The Kotlin library aids in the development of Android user interface apps. It comes with an interactive shell and may be used to write scripts.

C

The C programming language is the oldest and most widely used computer language. C is an imperative, general-purpose computer programming language that allows for organised programming. Dennis Ritchie worked on it between 1969 and 1973.

C++

Bjarne Stroustrup invented C with Classes, the forerunner to C+++, in 1979. C++ is a computer language that may be used for a variety of purposes. It offers features for imperative, object-oriented, and generic programming.

C++ is a compiled language with implementations on a variety of platforms. C++ has impacted other versions of programming languages such as Java, C#, D, and so on.

JavaScript

JavaScript is a high-level, interpreted programming language that is dynamic, loosely typed, and prototype-based. It has established itself as one of the web’s most important technologies. It allows you to make interactive web pages.

Conclusion:

A programming language is a tool that allows us to modify data in files as well as data in RAM in an infinite number of ways. We can do a wide range of data processing activities even if we just have a rudimentary understanding of programming.
