Programming languages now are used for calculating the actions of machines (very often a computer). Unlike human languages, the programming language has syntactic or semantic rules using a define meaning.
The language, C is the most basic language in the world. C++ is the extension version of it. The main comparison between these two is that C is a Procedural Programming Language but C++ is the object oriented programming language. Many more features are included in it. The main feature of C++ is the object and class which isn't present in the C language. C is weak than that of C++ of the globe of programming languages.
Perl and Pascal are another two languages of the programming world. Pascal is static while Perl are dynamic programming language. Pascal is a language like C or C++ while Perl is a language like PHP or .Net.
Ruby and Python another keys of the programming languages. These are almost same but the main comparison between these two is Python follows compilation while Ruby follows interpretation.
There are popular languages called Java. In 1995 there are another programming languages releases called JavaScript. These languages are totally different. Java is one of the object oriented programming languages while JavaScript is web scripting programming languages.
Another comparison takes place between .Net and PHP. Both are used to develop websites. .Net is not free but PHP is the most popular open source languages nowadays in the world. PHP may cross plat-formed but .Net may not. The hosting cost of PHP is less than .Net.
There may thousands of such programming languages and latest ones may create every year. A few languages become sufficiently accepted that they are using more than the few people, but a lot of professional programmers use dozen of special languages of their career.
