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)
(General math) a. Write a function named rightTriangle() that accepts the lengths of two sides of a right triangle as the arguments a and b. The subroutine should determine and return the hypotenuse, c, of the triangle. (Hint:UsePythagorastheorem,c2=a2+b2.) b. Include the function written for Exercise 4a in a working program. The main() function should call rightTriangle() correctly and display the value the function returns.
Test Average and Grade Write a program that asks the user to enter five test scores. The program should display a letter grade for each score and the average test score. Write the following functions in the program: calc_average. This function should accept five test scores as arguments and return the average of the scores. determine_grade. This function should accept a test score as an argument and return a letter grade for the score based on the following grading scale: Score Letter Grade 90–100 A 80–89 B 70–79 C 60–69 D Below 60 F Write the following functions: getTestScore(): This function prompts user for five test scores and returns test score to the caller. calcAverage(): This function accepts five test scores as arguments and returns the average of the five test scores. determineGrade(): This function accepts an average as an argument and returns a letter grade for the score based on the grading scale. displayData(): This method displays all five…
The Problem__: Write a program that calculates the average of a group of test scores, where the lowest score in the group is dropped. It should use the following functions: ⚫ void getScore() should ask the user for a test score, store it in a reference param- eter variable, and validate it. This function should be called by main once for each of the five scores to be entered. ⚫ void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores. ⚫int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop. Input Validation: Do not accept test scores lower than 0 or higher than 100. YOU MUST USE THE STATED FUNCTIONS AND COMPLETE Input VALIDATION. **DO NOT use an ARRAY OR GLOBAL VARIABLES!!. you MUST USE function prototyping TEST THE FUNCTION TWICE.…
Future Investment Value = investment amount * (1 + monthly interest)^(number of years * 12) Using this formula, write a function in Python called futureValue that prompts the user to enter an investment amount, an annual percentage interest rate, and the amount of years. The function should accept the input as arguments. The interest rate should have a default value of 7%. You can add default values of your choice for the amount of years. This function should print out a table that displays the future values. Demonstrate this function in another function called main. Format your output by two decimal places. Output Example: Enter the amount you want to invest: 1000 [Enter] Enter the interest rate for your investment: [Enter] Enter the number of years you want to invest this money: 30 [Enter] Years Future Value 1 1093.81 2 1196.41 ........ 30 14730.58

The prompt asks: Write a function that calculates the amount of money a person would earn over a period of years if his or her salary is one penny the first day, two pennies the second day, and continues to double each day. The program should ask the user for the number of years and call the function which will return the total money earned in dollars and cents, not pennies. Assume there are 365 days in a year. function totalEarned(years) { } var yearsWorked = parseInt(prompt('How many years will you work for pennies a day? ')); alert('Over a total of ' + yearsWorked + ', you will have earned $' + totalEarned(yearsWorked));
Question 1) Create a Python program called "test3_firstname_latename" with 2 function calls in the main body as shown below:add_star()longest_run() (These functions are defined later)1- In algebraic expressions, the symbol for multiplication is often left out, as in 3x+4y or 3(x+5). Computers prefer those expressions to include the multiplication symbol, like 3*x+4*y or 3*(x+5). Create a function called add_star() that asks the user for an expression. Your function must print the original expression and also the modified expression.You may assume the input expression is consisted of the following characters:Variable names are 0ne character long, i.e. xy is 2 variables x and y.Valid operators are +,-,* and /.( and ) charactersNumbers are of any length.Two examples are shown below: Please try to answer within 30 - 45 minutes.
Write in Python Write a function named max that accepts two float values as arguments and returns the value that is the greater of the two. For example, if 7.2 and 12.1 are passed as arguments to the function, the function should return 12.1. Use the function in a program that prompts the user to enter two float values. The program should display the value that is the greater of the two.
A bank charges $10 per month, plus the following check fees for a commercial checking account: $0.10 each for less than 20 checks $0.08 each for 20 through 39 checks $0.06 each for 40 through 59 checks $0.04 each for 60 or more checks Write a function BankCharges() that allows the user to enter the number of checks written and computes and displays the bank’s service fees for the month. All checks for the month are assigned the same charge, based on the total number of checks written during the month. Use the following test data to determine whether the application is calculating properly. In each case, the customer is charged only a single rate, based on the total number of checks. Your solution should clearly show the function. Customer Number of Checks Bank Charges Nancy 15 Lilian 25 Arianna 45 Ben 75
Create a function that calculates both compound and simple interest in python The user should be able to enter the sum invested, interest rate, duration in years and whether they wish to calculate simple or compound interest. The function should return the interest accrued and the final total amount. The resulting statement should be in this format: For , €100.00 invested at 2.0% Compound Interest for 1 year(s), you will earn €2.00 interest, and you will receive a total sum of €102.00.
