In Dr-Racket, which of the following is not necessarily true of a function that takes no arguments? A) It can result in side effects B) It might return (void) C) It might return a value like any other function D) It has the same result every time it is called, since it has no input arguments to deal with E) It is called like any other function, i.e. inside parentheses F) It can result in both side effects and return value

. What is the difference between a function argument and a function parameter? Group of answer choices An argument is a variable that is created in a function to hold a value that has been sent to it and a parameter value is the value that a function returns to the calling routine. An argument is a value that is passed into a function and a parameter is variable that the function defines to hold value of the argument. An argument is a value that is passed into a function and a parameter is the value that a function returns to the calling routine. A parameter is a value that is passed into a function and an argument is the value that a function returns to the calling routine.
What is the difference between a formal parameter and an argument? Group of answer choices A function’s argument is referred to as the formal argument to distinguish it from the value that is passed in during the function call. The parameter is the passed value. A function’s parameter is referred to as the formal parameter to distinguish it from the value that is passed in during the function call. The argument is the passed value. A function’s parameter is used for passing by reference. The argument is used for passing by value. A function’s parameter is used for passing by value. The argument is used for passing by reference. They are identical but using different terms.
true false void ffx() is a function with no return value void ffx() is a function with no argument int ffx(char x) is a function with int return value int ffx(char *x) is a function with parameter passed by reference char ffx( int x) is a function with int return value int ffc(char &x) is a function with parameter passed by reference
Explain why it may sometimes be useful for a function to have side effects.
True or False 1-int fx(char x) is a function with int return value 2-int fx(char &x) is a function with parameter passed by value 3-void fx(char ch) is a function with no return value 4-char fx( int x) is a function with int return value
1-int fx(char &x) is a function with parameter passed by value(False/True) 2-int fx(char x) is a function with int return value(False/True) 3-void fx(char ch) is a function with no return value(False/True) 4-char fx( int x) is a function with int return value(False/True)

Playing with Functions: Write a Javascript program to check if the argument passed to any function is a function type or not. I.e. Create a function check which takes a argument and check if that argument is a function or not.
For each of the following expressions, write functions f1, f2, f3, and f4 such that the evaluation of each expression succeeds, without causing an error. Be sure to use lambdas in your function definition instead of nested def statements. Each function should have a one line solution. f1 takes in nothing and returns 3. f2 takes in nothing and returns a function that takes in nothing and returns 3. f3 takes in nothing and returns a function that takes in 1 value and returns that same value. f4 takes in nothing and returns a function. This function takes in nothing and returns another function. This next function takes in a value and returns yet another function. This final function takes in nothing and returns the value passed into the previous function (if this explanation is confusing, have a look at the doctest, and it might be more clear). def f1(): >>> f1() 3 |||||| "*** YOUR CODE HERE ***" def f2(): |||||| >>> f2() () 3 |||||| "*** YOUR CODE HERE ***" def f3(): |||||| >>> f3() (3)…

PYTHON You Define a Function Part 1: Write a function that takes in one or two input parameters and returns an output. The function should return the output of a one-line expression. Write at least three test cases for your function in the docstring. Make sure your function has just one line of code Part 2: Write the same function as a lambda function.
INSTRUCTIONS: Write a C++ script/code to do the given problems. MOVIE PROBLEM: Write a function that checks whether a person can watch an R18+ rated movie. One of the following two conditions is required for admittance: The person is atleast 18 years old. • They have parental supervision. The function accepts two parameters, age and isSupervised. Return a boolean. Example: acceptIntoMovie(14, true) → true acceptIntoMovie(14, false) → false
