Description: Default argument values are predefined values used when an argument is not provided in a programming context. This feature allows developers to define expected behaviors and simplify function calls, as users do not always need to specify all parameters. By setting a default value, it ensures that the function works correctly even if some arguments are omitted. This not only enhances user experience but also reduces the likelihood of errors in function calls. Default values are particularly useful in situations where certain parameters are optional or have a commonly used value. In programming languages, these values are typically defined in the function or method signatures, allowing developers to have more granular control over how inputs are handled in their applications. Additionally, this functionality encourages code reuse and clarity in function definitions, as developers can focus on the arguments they truly need to modify, leaving others with their predefined values.
