- Programming Language : R programming (R Studio) A twin prime is a prime that has a prime gap of two. Sometimes the term twin prime isused for a pair of twin primes. For example, the five twin prime pairs are (3, 5), (5, 7),(11, 13), (17, 19) and (29, 31). Write a function that returns the number of all twin primepairs between 1 and a given number n.The following function has errors. Locate as many errors as you can. void getValue(int value&) { cout << "Enter a value: "; cin >> value&;}True/False 7. Python functions can never modify a parameter
- Topic: Function with default argument value covered in Chapter 6 Write a C++ Do not use any topic not covered in lecture. There is no need for use of loop, and needs the use of only an "if/else" statement. Write exactly these 3 functions: power(x,y), print(text, number) function and the main() function. The power(x,y) function returns an integer result that is calculated by raising a number x (integer) to a power y (integer). The second argument y (exponent) of the function can not exceed 100.If the second argument exceeds 100, the function should return -1. Your power(x,y) function must be able to take either 1 or 2 integer arguments using the concept of default argument in chapter 6. Look at the main() code to deduct what the default value should be. You should call C++ pow(x,y) function in the "cmath" library in the body of your power(x,y) function to avoid doing the power calculation yourself. The print(text, number) function is the only one that does output to the console using…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)5. A function can return a value of an enumeration type. True False
- Lowest Score Drop 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 parameter 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.python 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.Related to R code. Question: Write a function called temp_categorizer that takes one argument ‘temperature’ and returns the following: - a value of “hot” if temperature is greater or equal to 90 - a value of "warm" if temperature is greater than 60 but less than 90 - a value of "cold" if temperature is more than 32 but less than 60 - a value of "freezing" if temperature is 32 or below And also Use the following vector for problem number : sentence <- c("Learning", "loops", "in", "R", "is", "not", "that", "bad") Create a loop that: loops over the range of possible word lengths displays a message detailing the words that match the length For example: at length 8, the loop should state that the word "Learning" has 8 letters Hints: Use the function nchar() which gives the number of letters in each word. • Example: try nchar(sentence) min() and max() may help you specify a range
- Programming technique exercise Question 1). Write a complete C++ program that helps the teacher to calculate the result of students in the test of Programming Technique. The program should perform the following tasks: • Write a function named getinput. This is a non-returning function. It takes the score of question 1, score of question 2, and score of question 3 as input parameters. the function should ask the user to enter the score (per 100) for each question. It sends all the values entered by the user in (c) back to the calling module through the use of reference parameters. • Write a function named dispTier. This is a non-returning function. It takes the total marks as an input parameter. The function should display the tier based on the conditions. Tier 3 = below 40%, tier 2 = below75%, tier 1=75% and above • Write a function named calcAverage. I It takes the number of students and total marks as input parameters.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 daysHUK computer store offers credit plan at 10% down payment and an annual interest rate of 12%. You are required to write a C++ program to calculate and print the payment schedule for a loan to purchase a computer for the first month: a. Prompt the user for the purchase b. Write a void function called display() to print the following headings: The month number The starting balance The interest to pay The principal to pay The monthly payment The ending balance for that month c. Create a double function called creditcredit() that has the purchase price as its parameter. The function must do the following (d to j): d. Create two variables annual interest rate = 12% monthly rate = annual interest rate/12 e. The month number should begin with 1 f. Use a loop to display information for 12 months g. Monthly payment is calculated at 5% of the purchase h. The amount of interest for a month is calculated as the…
