Why do programming languages need a main function?

Most programming languages require a main function or entry point as the starting point for program execution. This is where the program begins running when you execute it.

What does the \n character mean?

The "\n" character represents a newline or line break in most programming languages. It moves the cursor to the next line after printing the text.

Is the generated code production-ready?

The generated code is for educational purposes only. While it demonstrates basic syntax, production code would require additional error handling, security considerations, and best practices specific to each language.
