There are over 20,000 third party modules available from the Comprehensive Perl Archive Network. Perl interfaces with external C/C++ libraries through XS or SWIG.Perl supports both procedural and object-oriented programming.Perl works with HTML, XML, and other mark-up languages.Perls database integration interface DBI supports third-party databases including Oracle, Sybase, Postgres, MySQL and others.Perl takes the best features from other languages, such as C, awk, sed, sh, and BASIC, among others. ![]() What are the features of Perl programming? The short code always makes sure that the project can be made user-friendly and it enables programmers to save a lot of time. Generally, they take more time to operate and thus becomes useless or of no preference for most of the users. Any software or application if have complex or lengthy code couldn’t work smoothly with the hardware and often have compatibility issues. Moreover, finding a bug in them is not at all a difficult job. While writing a program, why the code should be as short as possible?Ĭomplex codes are not always easy to handle. We can execute this program by just giving the following command in the command window: In this code, the first line “#!/usr/bin/perl”, is the path to the Perl interpreter. Though having a Perl IDE is useful, we can even write the Perl code in a notepad and then execute the program using the command prompt.įor Example, consider the following simple program to print “Hello, World!!” Explain the execution of a program in Perl.Īnswer: Perl is portable and Perl programs can be executed on any platform. Both of them can be executed in the function whenever there is a need of the same. The scalar variables are capable to hold a value of 1 digit while array can have more values. Both these variables have different namespace. An array on the other side is denoted by symbol. Scalar is generally denoted by symbol $ and it can have a variable which can either be a strong or a number. Can you name the variables in which the chomp works? Also, how they are different from one another? Perl has too many features that can be exhaustive for a programmer to comprehend.Īnswer: Perl is used in a mission-critical project – like the defense industry. Although it allows us to write high-level code, we cannot write complex code using Perl. The main disadvantage of Perl is that as it is an interpreted language, the execution speed is quite slow. For example, we can import CPAN modules for database support in the Perl program. We can include various open source packages and modules in a Perl program for any additional functionality. ![]() ![]() Currently, it can run on more than 100 platforms. Perl program is interpreted on a statement-by-statement basis.
