Question:

In Perl we can show the warnings using some options in order to reduce or avoid the errors. What are that options?

Answer:

-The -w Command-line option: It will display the list if warning messages regarding the code.

– strict pragma: It forces the user to declare all variables before they can be used using the my() function.

– Using the built-in debugger: It allows the user to scroll through the entire program line by line.
