- 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)arrow_forwardinteger) Write a function that computes the sum of the digits in an integer. Use the following function header:def sumDigits(n):For example, sumDigits(234) returns 9 (Hint: Use the % operator to extract digits, and the // operator to remove the extracted digit. For instance, toextract 4 from 234, use 234 % 10 To remove 4 from 234, use 234 // 10 (=23) Use a loop to repeatedly extract and remove the digits until all the digits are extracted.) Write a test program that prompts the user to enter an integer and displays the sum of all its digits.arrow_forward(FreshFood food[], Write a function named void findFreshFoodDetails int noFood) that prompt the user to input the fresh food details that he/she wants to view the price. Display the fresh food, production place and the total price of the selected fresh food according to kilogram as shown in Figure 4.3. Please enter the type of fresh food you wish to purchase: RED ONION Please enter the production place of RED ONION: INDIA Please enter the weight in kg that you want to view the price of the fresh food :3.5 Fresh Food: RED ONION Production Place: INDIA Total price of 3.5kg is RM 14.00 Figure 4.3. foodDetails.txtarrow_forward
- 1) In mathematics, a factorial of a number is calculated by multiplying that number by all of the successive values less than it, stopping at 1. For example, factorial of 4 is written 4! and calculated as: 4! = 4 * 3 * 2 * 1 = 24 2) Write a program consisting of two functions (plus the main function). The first function should read in a number and then return this value back to the main function. This value should then be passed as a parameter (by value) into the second function which calculates and displays the factorial. Note: validate the input value (in the first function) to be greater than 1. 3) Improve your program from question 2, by changing the second function (that calculates the factorial) so that the result is returned to the main function instead of being printed where it is calculated. A new display function should be created and called from the main function that displays the calculated value. 4) Write a program that reads in two numbers and stores them into two…arrow_forwardProgramming Exercise C++ Summary During the tax season, every Friday, the J&J accounting firm provides assistance to people who prepare their own tax returns. Their charges are as follows: If a person has low income (<= 25,000) and the consulting time is less than or equal to 30 minutes, there are no charges; otherwise, the service charges are 40% of the regular hourly rate for the time over 30 minutes. For others, if the consulting time is less than or equal to 20 minutes, there are no service charges; otherwise, service charges are 70% of the regular hourly rate for the time over 20 minutes. (For example, suppose that a person has low income and spent 1 hour and 15 minutes, and the hourly rate is $70.00. Then the billing amount is 70.00 X.40 X (45/60) = $21.00.) Instructions Write a program that prompts the user to enter yearly income, the hourly rate, the total consulting time. The program should output the billing amount. Your program must contain a function that takes as…arrow_forwardpython nMath: pentagonal numbers) A pentagonal number is defined as n(3n-1)/2 for n=1,2,..., and so on. So, the first few numbers are 1, 5, 12, 22, .... Write a function with the following header that returns a pentagonal number: def getPentagonalNumber(n): Write a test program that uses this function to display the first 100 pentagonal numbers with 10 numbers on each line.arrow_forward
- What are the benefits of using a function?arrow_forward1 - Nuclear Power Plant (python) The nuclear powerplant at Threeyedfish will automatically run a program to print a warning message when the reactor core becomes unstable. The warning message reads: NUCLEAR CORE UNSTABLE!!! Quarantine is in effect. Surrounding hamlets will be evacuated. Anti-radiationsuits and iodine pills are mandatory. Since the message contains crucial information, it should be printed three times. To do this, write a function that prints this message. This function has to be used three times.arrow_forward(Quality Points for Student’s Grades) Write a function toQualityPoints that inputs a student’s average and returns 4 it’s 90–100, 3 if it’s 80–89, 2 if it’s 70–79, 1 if it’s 60–69, and 0 if theaverage is lower than 60arrow_forward
- 1 year = 15 months 1 month = 30 days write a function that takes an int parameter that represents the number of days, and converts the number of days to years, months, and days and returns this information in a struct So for example, it will convert 800 days into a struct that represents one year, 11 months, and 20 daysarrow_forwardLanguage: Python 3 A particular talent competition has 5 judges, each of whom awards as score between 0 and 10 to each performer. Fractional scores, such as 8.3, are allowed. A performer's final score is determined by dropping the highest and lowest score received, then averaging the 3 remaining scores. Write a program that uses these rules to calculate and display a contestant's score. It should include the following functions: -getJudgeData() should ask the use for a judge's score, store in a parameter variable, and validate it. This function should be called by main program once for each of the 5 judges. -calcScore(score1, score2, score3, score4, score5) should calculate and return the average of the 3 scores that remain after dropping the highest and lowest scores the performer received. This function should be called just once by main and should be passed the 5 scores. Two additional functions, described below, should be called by calcScore, which uses the returned information to…arrow_forwardTopic: Recursive Function A bank increases the interest rate it gives to its customers by 1% every month the money stays in the bank.
