We can relate functions in programs to employees in an office in real life for a better understanding of how functions work.
#SAMPLE PROGRAM OF PERL PROGRAMMING LANGUAGE CODE#
When the programmer needs to do long calculations and cannot fit his statements into one line, one can easily divide it into multiple lines.Ī function/Subroutine is a block of code written in a program to perform some specific task. Every line between two semicolons is considered as a single statement.
Unlike other languages like Python, Perl looks for a semicolon to end the statement. Multi-Line Statements: Statements in Perl can be extended to one or more lines by simply dividing it into parts. For example, n = 50 is an assignment statement. These all help the user to get the required output. There are different types of statements in the Perl programming language like Assignment statement, Conditional statement, Looping statements, etc. Basically, instructions written in the source code for execution are called statements. every statement in Perl must end with a semicolon( ). These statements perform the operations on the variables and values during the Run-time. See the following code snippet demonstrating single line comment:Ī statement in Perl holds instructions for the compiler to perform operations. Perl’s single line comments are proved useful for supplying short explanations for variables, function declarations, and expressions. If the comment exceeds one line then put a hashtag on the next line and continue the comment. Single line comments: Perl single line comment starts with hashtag symbol with no white spaces (#) and lasts till the end of the line. These are often cited as a useful programming convention that does not take part in the output of the program but improves the readability of the whole program. Comments are usually helpful to someone maintaining or enhancing your code when you are no longer around to answer questions about it. It explains the logic or a part of it used in the code. Comments are useful information that the developers provide to make the reader understand the source code. Perl developers often make use of the comment system as, without the use of it, things can get real confusing, real fast. A Perl program whether it be a small code for addition of Two numbers or a Complex one for executing web scripts, uses these variables, statements and other parameters that comprise of a program’s syntax. All these, when put together, will make a Perl program. This syntax contains some predefined words known as Keywords, Variables for storing values, expressions, statements for executing the logic, loops for iterating over a variable value, blocks for grouping statements, subroutines for reducing the complexity of the code, etc.

Like other Programming Languages, Perl also follows a basic syntax for writing programs for applications and software or writing a simple Perl program. Perl is a lot similar to C syntactically and is easy for the users who have knowledge of C, C++. Perl supports both the procedural and Object-Oriented programming. Perl was originally developed for the text processing like extracting the required information from a specified text file and for converting the text file into a different form. Perl is a general purpose, high level interpreted and dynamic programming language.
