(Practice) For the following function headers, determine the number, type, and order (sequence) of values that should be passed to the function when it’s called and the data type of the value the function returns: a. int factorial(int n) b. double volts(int res, double induct, double cap) c. double power(int type, double induct, double cap) d. char flag(char type, float current, float time) e. int total(float amount, float rate) f. float roi(int a, int b, char c, char d, float e, float f) g. void getVal(int item, int iter, char decflag, char delim)
(Numerical) Heron’s formula for the area, A, of a triangle with sides of length a, b, and c is A=s(sa)(sb)(sc) where s=(a+b+c)2 Write, test, and execute a function that accepts the values of a, b, and c as parameters from a calling function, and then calculates the values of sand[s(sa)(sb)(sc)]. If this quantity is positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle, and the function should set A=1. The value of A should be returned by the function.
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)
Write the definition of a function that takes as input two decimal numbers and returns first number to the power of the second number plus second number to the power of the first number. (4)

What statement about the print() function is true? A. print() has a variable number of parameters. B. print() can have only one parameter. C. print() can be used to obtain values from the keyboard. D. print() does not automatically add a line break to the display. After a function calculates a value, how does it return that value to main program where it was called? A. By including that value in a return statement. B. By using the print() function C. By storing the value in a local variable. D. Since function variables are destroyed when the function call is completed, the calculated values are destroyed as well. Where in a program should a function be defined? A. At the very end B. Immediately after the first call to the function C. Near the top of the program D. Functions do not have to be defined to be used
Change this question to work using a function. decide what the name of the function of each should be, how many parameters are required and what value needs to be returned. You're no longer required to solve the problem - try to re-manage your code to be a function. write a program which prompts the user for a Celsius temperature, convert the temperature to Fahrenheit, and print out the converted temperature. c = float (input ("What is the temperature in Celsius? '")) f = c* (9/5)+32 print ("The temperature in Fahrenheit is:”,f)
To convert between Celsius and Fahrenheit, the following formula is used, where C = Celsius temperature and F = Fahrenheit temperature: C = 5/9 * (F-32) Write a C++ temperature conversion program which does the following: Write a function called toCelsuis which takes a Fahrenheit temperature as a parameter, and returns the equivalent Celsius temperature: float toCelsius(float) Demonstrate that your function works by writing a main() function that prints out a conversion table. It should have Fahrenheit values 60, 61, 62, ... through 80 (21 temperatures in total) and should also have the corresponding Celsius temperatures that your function calculated. So your output should look something like this (with 21 temperature conversions total, I used ... to save space here for most of them): Welcome to the temperature table!F C60 15.661 16.1... ...80 26.7 If you like: you can add this line in your function to make floating point output fixed, make sure you…
This is python Regarding a function, which of the following is not true? The def keyword is used to create a function. A function must contain a return statement. When a function is defined, it must have parentheses. A function can contain another function.
