Question

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

Answer 1

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.
