Which method of function calls allows the specification of which variables are passed to which parameters?

• A. Positional argument passing
• B. Keyword argument passing
• C. Mixed argument passing
• D. Reference argument passing

Answer: (B)

The method of function calls that permits the explicit specification of which variables are assigned to which parameters is known as keyword argument passing. In keyword argument passing, when invoking a function, you can include the name of the parameter along with its corresponding value. This means that no matter the order of the parameters in the function definition, you can assign values to those parameters in any sequence you prefer by using their names. For example, when you define a function that accepts multiple parameters and call it using keyword arguments, it enhances the readability of your code. It also allows you to omit certain parameters if they have default values set, providing greater flexibility in how you call the function. This method is particularly beneficial in functions with many parameters or when some parameters are optional, making it clear which values correspond to which arguments, thus preventing errors associated with positional argument passing.
