Perl
Living in an age of technology, the world is constantly coming up with new ways to make our lives easier (or sometimes more complex depending on how you look at it). Now with the help of the open source community, programming languages are blossoming from a small idea of a lonely programmer. Perl, a specialized language invented by Larry Wall, is a language that flourished in the hands of open source contributors.While working for the National Security Agency on a project known as "Blacker" Larry Wall created Perl. He was trying to produce some reports from a Usenet-news-like hierarchy of files for a bug-reporting system and the language he was using, awk, ran out of steam. He explained Perl's beginnings as follows:"The Beginnings of Perl were directly inspired by running into a problem I couldn't solve with the tools I had. Or rather, that I couldn't easily solve. As the Apostle Paul so succinctly put it, "All things are possible, but not all things are expedient." I could have solved my problem with awk and shell eventually, but I possess a fortuitous surplus of the three chief virtues of a programmer: Laziness, Impatience, and Hubris. I was too lazy to do it in awk because it would have been h
He felt that people weren't doing what he had hoped with the language and the Artistic License gave users even more freedom to change and enhance Perl. " He never created a newsgroup for Perl, instead he would writes posts on "how to do it in Perl" without the fear of "Take it to the Perl group" chants. A subroutine will also pass back the value of the last expression evaluated. The data is passed to the sort routine and sorts the data. Its author claims that Perl leaves out all the unwanted features of these languages and only combines their "cool" ones. This philosophy helped him to create a viable language that could be used for its specific task by anyone who was interested in performing that task well. html) The first letter of the variable name tells you what type it is. They had arbitrary limits and were often slow and non-portable. html)"Although strings and numbers are considered pretty much the same thing for nearly all purposes, references are strongly-typed, uncastable pointers with built-in reference-counting and destructor invocation. This means you can declare a scalar, an array, and a hash with the same name without worrying about conflicts. html) Perl is good for basically any type of text parsing because of its speed, and useful tools. But appearances can be deceiving, and a camel is well adapted to its ecological niche. html)One nice thing about Perl is that types are not limited to a certain size.
