This approach leverages built-in properties or methods provided by programming languages to determine the number of arguments passed to a function. These features make it simple to count the number of arguments dynamically.
Time Complexity: O(1) - Consistently returns a given number.
Space Complexity: O(1) - No additional space needed beyond the function's internal variables.

In C, we use the variadic function capability from the standard library. We define a function that takes at least one parameter, which will be the count of the arguments. The function simply returns this count.
This approach involves counting the arguments using a loop or other constructs to manually track the number of parameters. Although less commonly needed in modern languages due to built-in functionality, it's a potential way to understand argument storage deeply.
Time Complexity: O(1) - Due to usage constraints.
Space Complexity: O(1) - No additional space is used.
