حل تشریحی سوال شماره 21 زبان عمومی و تخصصی (انگلیسی)

Determining which programming language is the one most widely used is difficult, since the definition of usage varies by context. One language may occupy the greater number of programmer hours, a different one has more lines of code, and a third may consume the most CPU time. Some languages are very popular for particular kinds of applications. Other languages are regularly used to write many different kinds of applications. Various methods of measuring language popularity, each subject to a different bias over what is measured, have been proposed: counting the number of job advertisements that mention the language; the number of books sold that teach or describe the language; estimates of the number of existing lines of code written in the language - which may underestimate languages not often found in public searches: • counts of language references (i.e., to the name of the language) found using a web search engine. Through combining and averaging information from various internet sites, stackify.com has come up with the following list of the most popular programming languages for 2018 (in descending order by overall popularity): Java, C, C++, Python, C#, JavaScript, VB NET, R. PHP, and MATLAВ.
