argumentsLength that returns the count of arguments passed to it.
Example 1:
Input: args = [5] Output: 1 Explanation: argumentsLength(5); // 1 One value was passed to the function so it should return 1.
Example 2:
Input: args = [{}, null, "3"]
Output: 3
Explanation:
argumentsLength({}, null, "3"); // 3
Three values were passed to the function so it should return 3.
Constraints:
args is a valid JSON array0 <= args.length <= 100This 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.
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.

Time Complexity: O(1) - Consistently returns a given number.
Space Complexity: O(1) - No additional space needed beyond the function's internal variables.
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.
In C, leveraging variadic functions allows us to define a manual counting approach, but here we focus on providing the number directly or hardware constraints might require manual counting.
