Learn how to concatenate strings in Perl.
- [Voiceover] The string concatenation operator…is used for combining strings.…Here's a working copy of strcat.pl…from Chapter Eight of the exercise files.…String concatenation is very simple, two strings combined,…one after the other with no separation.…So when I go ahead and I run this,…you'll see it says, "Hello, world," and you'll notice…that there is no separation between the two words.…That's because the strings are simply concatenated.…One string is put right at the end of another string,…and the two strings are combined…without anything in between them.…
If you want some separation in between them,…you can concatenate another string…and put that separation in that other string,…like that, and I can run this and now I have…hello comma space world.…Course, string concatenation works…with more than two strings,…say str three equals more…and I can do the same thing here,…I can put in another separator…and dollar str three,…and I can run that…and it now says "more" at the end there.…
Later in this course, we'll discuss the join function…
Watch to learn the details of the Perl syntax, from variables, conditionals, loops, and data structures to regular expressions, functions, and references. A quick-start guide is included for experienced developers who want to get up and running with Perl 5 fast, and the entire course is recommended for both new and experienced programmers alike. Later chapters cover file handling and reusing code with Perl modules, plus Perl best coding practices.
