Definition – What is High-Level Programming Language?
A high-level programming language is a programming language that is intended to be considered as the 3rd generation of the programming language evaluation. The main purpose of the development of this 3rd generation or high-level programming language is to simplify the programming procedure and user-friendly for the computer programmers. A high-level programming language allows the programmers to read the source code easily that is called human-readable rather than machine code or machine readable.
Every high-level language is either interpreted languages or compiled languages. Because the computer can not read the high-level source code directly. Before executing and running an application written in a high-level language first, it must have to be compiled or interpreted by a compiler or interpreter.
Compiler and interpreter convert the high-level source code into low-level source code or machine readable code (binary form). Dozens of high-level has been developed, for example, C, C++, Java, Python, PHP, Go, Erlang, F#, etc are considered as high-level programming languages or third generation programming languages.
Explanation – High-Level Programming Language
Building application using a high-level language is easier than using a low-level language like machine-language or assembly language. Nowadays, for building interactive and high-quality application most of the time high-level language is used. Because coding in a high-level language is much easier than a low-level programming language. Moreover, tracking and finding bugs is easier than a low-level programming language.
However, these days for many complex purposes, still the low-level language used basically in system programming for complex computing. Usually, implementing the software code directly with hardware requires machine languages or assembly language.
Here machine language is considered as 1st generation language. Which can be implemented directly with the hardware. But Assembly language is considered as 2nd generation language. To implement assembly code an assembler is required. And programs written in assembly language is easier to read and understand compared to machine code
