What are two examples of valid function calls?

Rationale

round_number(4.723, 2) and PrintSample() are examples of valid function calls.

Both function calls follow the correct syntax for calling functions in programming, including appropriate parameter types and no syntax errors. These examples demonstrate valid usage within typical programming languages, allowing for successful execution of the respective functions.

A (function Sample(float 2.0)) YOUR ANSWER

This choice is incorrect because the syntax for defining a function is not valid; specifically, "function" is not a proper keyword in many programming languages, and the parameter should not include a numeric literal as its name. Additionally, function calls cannot use type declarations directly in this manner.

B (round_number(4.723, 2)) CORRECT

This choice is correct as it adheres to the standard function call format, providing valid parameters (a float and an integer) to the function. The call is properly structured, allowing the function to execute and return a rounded number.

C (GetHeight(Integer 3, integer 4)) YOUR ANSWER

This option is incorrect because it improperly uses type declarations in the function call. Function calls should use values instead of specifying types in this context. The correct usage would simply include the values without type annotations.

D (convert_value(12) returns cVal) YOUR ANSWER

This choice is invalid as it combines a function call with a return statement, which is not properly formatted. A function call should not include a return statement; instead, it should simply execute the function.

E (PrintSample()) CORRECT

This choice is correct as it represents a valid function call without parameters, which is syntactically correct. This call is straightforward and adheres to the expected format for invoking a function.

F (CountFactors(96 integer)) YOUR ANSWER

This choice is incorrect due to the inclusion of a type declaration in the function call. Function calls should only include the values being passed, not type identifiers, making this syntax invalid.

Conclusion

Valid function calls must adhere to the syntax rules of the programming language being used. In this case, round_number(4.723, 2) and PrintSample() are correctly formed calls, while the others fail due to syntax errors or misuse of type declarations. Understanding these rules is essential for successful programming and function execution.
