Select the correct answerGiven a function that does not return any value, What value is thrown by default when executed in shell.OptionsintvoidNonebool

To determine the default return value of a function that does not explicitly return a value when executed in a shell context, we need to understand how functions operate in programming languages like Python, JavaScript, or C.

1. Break Down the Problem:

   • A function that does not have a return statement or does not return a value.
   • Understanding the possible return values given in the options.

2. Relevant Concepts:

   • In many programming languages, when a function does not return a specific value, it typically returns a default value.
   • Common defaults include "None" in Python, "null" in Java or JavaScript, and "undefined" in JavaScript.

3. Analysis and Detail:

   • int: This option suggests an integer value which is not applicable.
   • void: This is often used in languages like C and C++ to indicate a function does not return any value, but it's not directly a return value.
   • None: In Python, the default return value for a function that does not explicitly return a value is indeed "None".
   • bool: This suggests a boolean value, which is also not applicable in this case.

4. Verify and Summarize:

   • After analyzing the options, the most appropriate choice for a function that does not return any value in the context of common programming languages is "None".

Final Answer

The correct answer is None.
