For this question you will design and implement a function that takes 5 arguments and produces 5 return values. This question is internally recognized as variant 0371. The 5 arguments must be of types int, int, bool, bool, and char (in that order), and they must be stored in parameter variables 'ham', 'bar', 'xyz', 'gzk', and 'foo', respectively. As a clarifying example, the second parameter - 'bar' - will be of type int. The function you create must perform the operations list below, in the specified order and exactly as they are described here. You are NOT permitted to simplify the operations. 1. create a new variable named 'ukr' that stores the result of increasing the 'ham' parameter by 42 2. if the conjunction of the 'xyz' parameter and the 'gzk' parameter has a value of True, multiply the value of the 'ham' parameter by a value of 29 and store the result back in 'ham' 3. negate the value of the 'xyz' parameter and store the result back in 'xyz' 4. decrease the value of the 'ham'…
Exercise 9-6: Pass by Reference and Pass by Address In this exercise, you use what you have learned about passing arguments by reference and by address to functions to answer Questions 1-2. 1. Given the following variable and function declarations, write the function call and the function's header a. double price 22.95, increase .10; void changePrice(doubl e&, double); b. double price 22.95, increase .10; void changePrice (double*, double); c. int age = 23; void changeAge(int&); d. int age 23; void changeAge (int*); 2. Given the following function headers and variable declarations, write a function call: a. custNames [] = {"Perez", "Smith", "Patel", "Shaw"}; balances [] = {34.00, 21.00, 45.50, 67.00); void cust (string name [], double bal []) b. int values [] = {1, 77, 89, 321, -2, 34}: void printSum (int nums [])
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)
(Practice) For the following function headers, determine the number, type, and order(sequence) of the values that must be passed to the function: a. void factorial(int n) b. void volts(int res, double induct, double cap) c. void power(int type, double induct, double cap) d. void flag(char type, double current, double time) e. void total(double amount, double rate) f. void roi(int a, int b, char c, char d, double e, double f) g. void getVal(int item, int iter, char decflag, char delim)
36- Consider the following function call: min(x, y) What is the function name and what is the first argument? a. The function name is min and the first argument is x b. Functions in Python don't have names (they're anonymous functions), but the first argument is x. c. The function name is min, but you need to see the function definition to determine the arguments. d. Functions in Python don't have names (they're anonymous functions) and you need to see the function definition to determine the arguments
6...Consider the definition of the function main. int main() { double rate, hours, amount; . . . } Each of the functions described must have the appropriate parameters to access these variables. Write the following definitions: a. Write the definition of the function getHoursRate that prompts the user to input the hours worked and rate per hour to initialize the variables hours and rate of the function main. b. Write the definition of the value-returning function payCheck that calculates and returns the amount to be paid to an employee based on the hours worked and rate per hour. The hours worked and rate per hour are stored in the variables hours and rate, respectively, of the function main. The formula for calculating the amount to be paid is as follows: For the first 40 hours, the rate is the given rate; for hours over 40, the rate is 1.5 times the given rate. c. Write the definition of the function printCheck that prints the hours worked, rate per hour, and the salary. d. Write the…

Inspect the code and in your own interpretation, describe the reason parameter n inChangeIt_2(int *n) is a pointer, and statement in the function is *n = 6 ? 3. Write a function called void swap with two parameters, which will receive the addressof x and y as pointer. The function should swap the value of x and y only if x is larger thany. Print the value of x and y after the function call. 4. Write a function called double getAverage(int *array, int SIZE), whereit accept the array as pointer, and return the average of the array. Print the returnedvalue from this function. Always use *array rather than subscript to access the arrayvalue.

assume the availability of a function is_prime. Assume a variable n has been associated with a positive integer. Write the statements needed to compute the sum of the first n prime numbers. The sumer should be associated with teh variable total. this should be done in Python. is_prime takes an integer as a parameter and returns True if and only if that integer is prime
