Question 12

Function name is required for all function calls.

Every function call must include a function name to specify which function is being invoked. This is essential for the program to identify the correct code block to execute.

A) Output values

Output values are not required for function calls. While functions may return values, the act of calling a function does not necessitate the presence of output; the function can be called purely for its side effects or operations.

B) Function name

The function name is crucial for all function calls because it directly indicates which specific function the program should execute. Without a function name, the call cannot be recognized, leading to errors.

C) Parameters

Parameters are not required for every function call. While some functions require parameters to operate, others may not take any or may utilize default parameters, making them optional in certain contexts.

D) Input arguments

Input arguments, similar to parameters, are not universally required for all function calls. A function can be called without any input arguments if it is designed to work without them, and this does not affect the validity of the function call.

Conclusion

The necessity of a function name in function calls is paramount, as it determines the execution of the desired function. All other options, while potentially relevant in specific contexts, do not hold the same universal requirement, thereby solidifying option B as the correct choice.
