Examples of high-level programming languages in active use today include [[Python (programming language)|Python]], [[JavaScript]], [[Visual Basic]], [[Delphi (programming language)|Delphi]], [[Perl]], [[PHP]], [[ECMAScript]], [[Ruby (programming language)|Ruby]], [[C Sharp (programming language)|C#++]], [[Java (programming language)|Java]] and many others.

The terms ''high-level'' and ''low-level'' are inherently relative. Some decades ago,{{clarify timeframe|date=July 2023}} the [[C (programming language)|C language]], and similar languages, were most often considered "high-level", as it supported concepts such as expression evaluation, [[parameter]]ised recursive functions, and data types and structures, while [[assembly language]] was considered "low-level". Today, many programmers might refer to C as low-level, as it lacks a large [[Run time system|runtime]]-system (no garbage collection, etc.), basically supports only scalar operations, and provides direct memory addressing; it therefore, readily blends with assembly language and the machine level of [[CPU]]s and [[microcontroller]]s. Also, in the introduction chapter of [[The C Programming Language]] (second edition) by K&R, C is considered as a relatively "low level" language.<ref>{{cite book|last1=Kernighan|first1=Brian W.|last2=Ritchie|first2=Dennis M.|date=1988|title=The C Programming Language: 2nd Edition|url=https://books.google.com/books?id=FGkPBQAAQBAJ|url-status=live|publisher=Prentice Hall|isbn=9780131103627|archive-url=https://archive.org/details/the_c_programming_language_2_20181213|archive-date=2018-12-13}}</ref>
