- Variable that are listed in function's calls are called Actual parameter Declared parameter Passed parameter None of themarrow_forwardFunction Name: compliments Parameters: answer1 - a boolean (True or False) representing whether the user is "smart" answer2 - a boolean (True or False) representing whether the user is "awesome" answer3 - a boolean (True or False) representing whether the user is "fun" Description: Write a function that outputs a string of compliments based on the adjectives selected by the inputs. Use the inputs True and False. The function should return the string “You are” concatenated with the compliments that are true. The three compliments should be: "smart" "awesome" and "fun". If none of the compliments are true, print the string “Goodbye.” instead. Test Cases: >>>compliments(True, True, True) You are smart awesome fun. >>>compliments(False, True, False) You are awesome. >>>compliments(False, False, False) Goodbye.arrow_forwardLocal variables are known only to the function in which they are declared. Local variables are invisible outside the function in which they are declared. Whether True or False 11. It is possible for any function to return numerous values. Any function type may return multiple values. That's true, right?arrow_forward
- In C/C++, True or False: A function that changes the value of a variable passed by reference also changes the value of the original variable. A variable's type helps define the amount of memory it takes to hold a value of that type.arrow_forwardWhich of the following statement will be correct if the function has three arguments passed to it? A. The trailing argument will be the default argument.B. The first argument will be the default argument.C. The middle argument will be the default argument.D. All the argument will be the default argument.arrow_forwardWrite the function header for a function fun1 that will be receiving one number as a parameter. Write the call to the function from main, passing a number to the function.arrow_forward
- Which statement of the following is the most appropriate? Group of answer choices One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function. One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function. These form a contract between the programmer who uses the function and the programmer who writes the function. Using the assert function to check preconditions can significantly reduce debugging time, and the assertion-checking can later be turned off if program speed is a consideration.
