- Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)Why would you want to use a return statement in a void function, you may wonder.In python, write a function that receives three parameters: name, weight, and height. The default value for name is James. The function calculates the BMI and returns it. BMI is: weight/(height^2). Weight should be in kg and height should be in meters. For instance, if the weight is 60 kg and the height is 1.7 m, then the BMI should be 20.76. The function should print the name and BMI. The function should return 'BMI is greater than 22' if the MBI is greater than or equal to 22. Otherwise, the function should return 'BMI is less than 22'. Call the function and print its output.
- Write a declaration for a function called test( ) that takes 2 arguments and returns type char. The first argument is type int and the second is type float with a default value of 5What is the best statement about the following function, f1? void f1 (int i) { int j; for (j = 0; j < i; ++j); cout << ‘*’; cout << endl; } Group of answer choices The f1 function prints a star. The f1 function prints a start on the ith line. The f1 function prints a line of i-1 stars. The f1 function prints a start on each of the i lines. The f1 function prints a start on each of the i-1 lines.You are creating a function that manipulates a number. The function has the following requirements:-> A float is passed into the function-> The function must take the absolute value of the float-> Any decimal points after the integer must be removedWhich two math functions should you use? Each correct answer is part of the solution. (Choose two.) Group of answer choices math.floor(x) math.frexp(x) math.ceil(x) math.fmod(x) math.fabs(x)
- You are given a function called is_prime which consumes a positive number and returns True if the number is prime and False if the number is not prime. You do not need to write the is_prime function - it is already pre-defined. Your task is to use the Design Recipe to write a main function, that consumes no parameters, which prompts the user for a positive integer, n, and displays the first n primes. Your main function should call the is_prime function. Include a docstring!Which 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.If a function is supposed to just display a message, which is more appropriate to use--a value-returning function or a void function?explain please
- The ceiling of a floating-point number x is the smallest integer that is still larger than or equal to x. Alternatively, the ceiling of a floating-point number x is what you get when you round x up to the nearest integer. For example, the ceiling of 2.1 is 3, the ceiling of 0.9 is 1, the ceiling of -4.5 is -4, etc. Write a function called ceiling() to compute the ceiling of a float input parameter that returns one integer value. You may not use python’s ceil() or floor() functions. Your function may use int()/float() functions, and the floor division operator (i.e., '//').Write a split_check function that returns the amount that each diner must pay to cover the cost of the meal. The function has 4 parameters: bill: The amount of the bill. people: The number of diners to split the bill between. tax_percentage: The extra tax percentage to add to the bill. tip_percentage: The extra tip percentage to add to the bill. The tax or tip percentages are optional and may not be given when calling split_check. Use default parameter values of 0.15 (15%) for tip_percentage, and 0.09 (9%) for tax_percentage. Sample output with inputs: 25 2 Cost per diner: 15.5 Sample output with inputs: 100 2 0.075 0.21 Cost per diner: 64.25 python # FIXME: Write the split_check function. HINT: Calculate the amount of tip and tax,# add to the bill total, then divide by the number of diners. ''' Your solution goes here ''' bill = float(input())people = int(input()) # Cost per diner at the default tax and tip percentagesprint('Cost per diner:', split_check(bill, people)) bill =…In physics, an object that is in motion is said to have kinetic energy. The following formula can be used to determine a moving object’s kinetic energy:KE=12mv2The variables in the formula are as follows: KE is the kinetic energy, m is the object’s mass in kilograms, and v is the object’s velocity in meters per second. Write a function named kinetic_energy that accepts an object’s mass (in kilograms) and velocity (in meters per second) as arguments. The function should return the amount of kinetic energy that the object has. Write a program that asks the user to enter values for mass andvelocity, then calls the kinetic_energy function to get the object’s kinetic energy.
