Perl Tutorial For Beginners : Pondy IT Training
Perl stands in for "Practical Extraction and Reporting Language" even though there is no authorized acronym for Perl. You may create your own acronym, and no one will mind. Perl was created by Larry Wall in 1987 when he was employed on a bug reporting system and "AWK"- a programming language he was using for the purpose was not helping him much. He is still the chief architect and developer of Perl. If we want to define Perl in one sentence: Perl is a high-level, interpreted, dynamic programming language.

Now, we'll talk about variables. You can imagine variable like kind of container which holds one or more values. Once defined, the name of variable remains the same, but the value or values change over and over again.
- Scalar Variable
- Integer literals
- Floating-point literals
- Octal, Hexadecimal and Binary representation
An Array is a special type of variable which stores data in the form of a list; each element can be accessed using the index number which will be unique for each and every element. You can store numbers, strings, floating values, etc. in your array.
- Sequential Array
- Perl Array Size
- Dynamic Array
- Push, Pop, shift, unshift for Perl arrays
A hash can also hold as many scalars as the array can hold. The only difference is we don't have any index rather we have keys and values. A hash can be declared, starting with % followed by the name of the hash. Let's see an example how we can define a Perl hash and how we can differentiate this from array
- Why do we need Hash?
- What are Hashes?
- Add Perl Hashes
- Perl Delete key
We can use conditional Statements in Perl. So, what are conditional statements? Conditional statements are those, where you actually check for some circumstances to be satisfied in your code.
- Perl If
- Perl If Else
- Perl Else If
- Perl Nested If
- Perl Unless
- Perl Using if
- Using unless
Perl supports control structures similar to other programming languages. Perl supports four types of control structures for, foreach, while and until. We use these statements to, repeatedly execute some code.
- For loop Perl
- Perl Foreach
- Perl While
- Perl do-while
- Perl until
- Perl do-until
Operators in computer language indicate an action that can be performed on some set of variables or values which computer can understand. Perl has incorporated most of the Operators from C language. Perl has many operators compared with other programming languages. Operators are categorized as Arithmetic, Logical, relational and assignment operators.
- Arithmetic Operators
- Assignment Operators
- Logical and Relational Operators
Special variables in Perl are those who have some predefined meaning. These variables denoted with either real Name or Punctuation symbols. We have a special variable for all the Perl supported Variables like scalar special variables, Array special variables, hash special variables. Most of the special variables that we use are of scalars.
- Scalar special variables
- Array Special Variables
- Hash Special Variables
