High-Level Langauge

Last Updated on August 9, 2023 by Mayank Dham

High-level programming languages have revolutionized the way we develop software applications. These languages enable developers to craft code that closely resembles human language, simplifying the processes of comprehension, composition, and upkeep. This composition explores the realm of high-level languages, delving into their merits and demerits, and providing instances of such languages.

What is High-Level Language?

High-level programming languages empower individuals to create computer programs and engage with computer systems without requiring knowledge of the specific processor or hardware on which the program will execute.

High-level languages use command words and syntax that are similar to everyday language, making them easier to learn and apply. High-level languages also provide developers with development tools like libraries and built-in functions.

High-Level Language Examples

Here we have high-level languages examples which are C, C++, Java, Python, Javascript, etc

1) C

C was created in order to create the UNIX operating system. C is also a portable language, which means that programs written in C can be compiled to run on different platforms and operating systems. This is possible because C compilers are available for many different architectures and operating systems.
C is the successor to the B language, which was first introduced in the early 1970s.
The American National Standard Institute formalized the language in 1988. (ANSI).
The UNIX operating system was entirely written in C. Today, C is the most popular and widely used System Programming Language.
The majority of cutting-edge software has been written in C. The most popular Linux operating system and RDBMS, MySQL, were written in C.

2) C++

C++ is a statically typed, compiled, general-purpose, case-sensitive, free-form programming language that can be used to write procedural, object-oriented, and generic code.C++ is classified as a middle-level language because it combines high-level and low-level language features.

C++ was created by Bjarne Stroustrup in 1979 at Bell Labs in Murray Hill, New Jersey, as an enhancement to the C language. It was initially called C with Classes before being renamed C++ in 1983.C++ is a superset of C, which means that almost any legal C program is also a legal C++ program.
C++ supports object-oriented programming, allowing developers to create classes and objects, as well as define methods and properties for these objects. Templates: C++ templates enable developers to write generic code that can work with any data type, making reusable and flexible code easier to write.
STL (Standard Template Library): The STL provides a diverse set of data containers and algorithms, making it easier to write efficient and effective code.

3) Java

Java is a high-level, object-oriented programming language that was originally developed by Sun Microsystems (now owned by Oracle Corporation) in the mid-1990s. It is designed to be platform-independent, which means that programs written in Java can run on any platform that supports a Java Virtual Machine (JVM).

Java is widely used for developing enterprise applications, web applications, and mobile applications. It provides a rich set of libraries and frameworks that make it easy to develop complex applications. Some of the key features of Java include automatic memory management, garbage collection, and exception handling.

4) Python

Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built-in data structures, combined with dynamic typing and dynamic binding, make it very desirable for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. Python’s simple, easy-to-learn syntax emphasizes readability, lowering the cost of program maintenance. Python supports modules and packages, which promotes program modularity and code reuse. The Python interpreter and extensive standard library are freely distributable and available in source or binary form for all major platforms.

5) Javascript

JavaScript is a dynamic computer programming language. It is lightweight and is most commonly used as part of web pages, where implementations allow client-side script to interact with the user and create dynamic pages. It is an interpreted programming language with object-oriented capabilities.

JavaScript was originally known as LiveScript, but Netscape changed its name to JavaScript, possibly due to the excitement generated by Java. JavaScript first appeared in Netscape 2.0 in 1995 as LiveScript. The language’s general-purpose core has been embedded in Netscape, Internet Explorer, and other web browsers.

All these are high-level language examples.

Advantages of High-Level Language

Below we have the advantages of High-Level Programming Languages are:

  • Abstraction and Simplification: High-level languages provide a higher level of abstraction, allowing programmers to focus on the logic and functionality of their programs rather than the intricate details of hardware or low-level operations.
  • Readability and Maintainability: Code written in high-level languages is often more readable and understandable, making it easier for programmers to collaborate, debug, and maintain software projects over time.
  • Productivity: High-level languages offer built-in functions, libraries, and frameworks that expedite the development process. This boosts productivity and enables faster creation of complex applications.
  • Portability: Programs written in high-level languages are generally more portable, as they are not tightly bound to a specific hardware architecture. This allows code to be executed on different platforms with minimal modifications.
  • Reduced Errors: The abstraction and automation provided by high-level languages reduce the likelihood of human errors, such as memory management issues, that are common in low-level languages.
  • Rapid Development: High-level languages often provide features like dynamic typing, automatic memory management, and concise syntax, enabling rapid prototyping and development of software applications.
  • Community and Resources: Popular high-level languages have large and active communities, resulting in extensive documentation, tutorials, and online resources that aid programmers in learning and problem-solving.
  • Enhanced Security: Many high-level languages include security features and mechanisms that help prevent common vulnerabilities, contributing to safer software development.
  • Easier Learning Curve: High-level languages are typically easier to learn for newcomers to programming, as they abstract away low-level complexities and allow beginners to focus on coding concepts and problem-solving.

Disadvantages of High-Level Language

Below we have the disadvantages of High-Level Programming Languages are:

  • Slower execution: High-level languages are generally slower than low-level languages, as they require more processing time to convert their code into machine code.
  • Less control: High-level languages abstract away low-level details and hardware-specific functions, making it difficult to optimize code for specific hardware or systems.
  • Higher memory usage: High-level languages require more memory than low-level languages, as they use additional functions and structures to provide more organization and structure to code.

We can conclude that high-level programming languages have revolutionized the way we develop software applications. They offer many advantages over low-level languages, including ease of use, portability, and efficiency. However, they also have some disadvantages, such as slower execution and higher memory usage. It is important to choose the right programming language for a particular project, taking into account its advantages and disadvantages, and the specific needs of the application high level language examples are C++, Ruby, Javascript, Java, Python, C, etc
