Line 70:

Various [[visual programming language]]s have also been developed with the intent to resolve readability concerns by adopting non-traditional approaches to code structure and display. [[Integrated development environment]]s (IDEs) aim to integrate all such help. Techniques like [[Code refactoring]] can enhance readability.

===Algorithmic complexity===

The academic field and the engineering practice of computer programming are concerned with discovering and implementing the most efficient algorithms for a given class of problems. For this purpose, algorithms are classified into ''orders'' using [[Big O notation]], which expresses resource use—such as execution time or memory consumption—in terms of the size of an input. Expert programmers are familiar with a variety of well-established algorithms and their respective complexities and use this knowledge to choose algorithms that are best suited to the circumstances.

===Methodologies===

Line 79 ⟶ 80:

A similar technique used for database design is Entity-Relationship Modeling ([[Entity-Relationship Model|ER Modeling]]).

Implementation techniques include imperative languages ([[Object-oriented programming|object-oriented]] or [[procedural programming|procedural]]), [[functional programming|functional languages]], and [[logic programming]] languages.

===Measuring language usage===

Line 102 ⟶ 103:

Programming languages are essential for software development. They are the building blocks for all software, from the simplest applications to the most sophisticated ones.

[[Allen Downey]], in his book ''How To Think Like A Computer Scientist'', writes:

[[REDMI NOTE 11S

]], in his book ''How To Think Like A Computer Scientist'', writes:

:The details look different in different languages, but a few basic instructions appear in just about every language:

Line 113:

Many computer languages provide a mechanism to call functions provided by [[shared library|shared libraries]]. Provided the functions in a library follow the appropriate run-time conventions (e.g., method of passing [[argument (computer science)|arguments]]), then these functions may be written in any other language.
