Understanding the Difference Between "my" and "our" in Perl
When working with variables in Perl, it's important to grasp the distinction between the keywords "my" and "our". These keywords serve different purposes and scopes in the language.
Focus Keyword: Difference Between "my" and "our" in Perl
My:
The "my" keyword is used to declare a variable that is lexical in scope. This means that the variable is only accessible within the block of code in which it was declared. It is a private variable and not visible outside of its scope. This is commonly used for creating local variables that are limited to a specific portion of code.
Our:
On the other hand, the "our" keyword is used to declare a variable that is global in scope. This means that the variable is accessible throughout the entire package in which it was declared. It allows variables to be shared and accessed across different parts of the code, making it suitable for defining variables that need to be accessed globally.
By understanding the difference between "my" and "our" in Perl, you can effectively manage variable scopes and ensure the proper functioning of your code.
