Write a function that returns a decimal number from an octal number. The function header is as follows: int octal2Dec(const int& octalNumber) For example, octalNumber 345 is 229 (3 * 82 + 4 * 81 + 5 * 80 = 229). So, octal2Dec("345") returns 229. Write a test program that prompts the user to enter an octal number and displays its decimal equivalent value.
Create a function that takes one, two or more numbers as arguments and adds them together to get a new number. The function then repeatedly multiplies the digits of the new number by each other, yielding a new number, until the product is only 1 digit long. Return the final product. Examples sumDigProd (16, 28) -6 // 16 + 28 = 44 // 4 * 4 16 // 1 * 6 = Notes = 6 sumDigProd (0) - 0 sumDigProd (1, 2, 3, 4, 5, 6) - 2 The input of the function is at least one number.
please code in python Find the Error The following function takes in a positive integer and returns True if the integer is divisible by at least one integer between 2 and 7, inclusive, or False otherwise. Or at least, that’s what it’s supposed to do; there is a logic error that causes it to fail (for example, it should return True when passed in 15, but it returns False instead). Find the error and fix it. If you’re working in a pair, make sure that both of you are able to explain the error to your TA. Hints: As with most logic errors, the first thing you should do is put in print statements. Print out what i is at each step of the loop. At what point can you safely return False (that is, how many values of i do you have to check before you can be sure num isn't divisible by any of them)? def div27(num): for i in range(2,8): if num % i == 0: return True else: return False
1-int fx(char &x) is a function with parameter passed by value(False/True) 2-int fx(char x) is a function with int return value(False/True) 3-void fx(char ch) is a function with no return value(False/True) 4-char fx( int x) is a function with int return value(False/True)
Write a program that generates random numbers between -25 and 25 by using the randint function. The program will add up the numbers and terminate when the sum of the values becomes zero. The program should contain the following functions: add() : add up the values main(): the function where the program execution should begin and end. randomgen(): a function that returns a number between -25 and 25 A global variable subsetsum that keeps track of the sum The program should output the count of the number of values generated before exiting saying that the subset sum was zero.
8 There are different ways you can determine whether a person is healthy or over weight weight height - 100 of measure = a) define a function that takes two parameters height and weight and calculates the measure and returns a message ' Healthy if measure= 1. estion b) Accept two inputs height and weight c) Write an appropriate function call using the inputs. Run and test your program. Once done, you can submit the program in the following link https://moodle.nct.edu.om/mod/quiz/view.php?id%3D64872
a. Write a function called IsPalindrome that receives a 3-digit number and returns whether it is palindrome or not. b. Write a function, called GCD that receives two parameters n, d, and prints their greatest common divisor a. Now after you created the two functions, you have to write a main function that can call the above functions according to user choice. Write a menu that allows the user to select from the following options 1. To use the IsPalindrome function you have to enter 1. 2. To use the GCD function you have to enter 2. 3. To Exit the program you have to enter 3. [use exit(0)] Once the user select one of the above choices you have to read the value entered by the user and then to call the respective function.
Consider the following code def f(a, b): if a > 3: return a, b-a return a+b, b you can call the above function as Select one: a. x1,x2,x3,x4=f(10,20) b. x1,x2,x3=f(10,20) c. x1=f(10,20) d. x1,x2=f(10,20)

What is a stub? Group of answer choices A stub is an inline function with a single line that simply sends a "Hello" message to others, indicating that it has been activated. A stub is a function that has an empty body. It will be developed later. A stub is an inline function with a single line that simply increases the pass in value by one. A stub is a function with a single line that simply prints the name of the function, indicating that it has been activated. A stub is a short function that will generate an error message.
Create a function that counts the integer's number of digits. Examples count (318) → 3 count (-92563) → 5 count (4666) -4 count (-314890) -6 count (654321)→ 6 count (638476) <- 6
Q2: marks.py Write and execute a program to do the following: - 1) Ask the user the user to input marks in integer for 10 students. You can use the following marks as initial values 131. 90 60 59 4 88 69 88 92 2) Define a function that takes an integer mark and returns its letter grade according to the following table :- Grade A Mark 90 s mark 80 s mark < 90 60 s mark < 80 mark <60 3) Call the above function to calculate the letter grade for each student and store it in the new list Grade 4) Calculate average of all marks. 5) Calculate number of students whose letter grade is "A". 6) Calculate number of students with marks greater than average. 7) Display your output as follows: - Mark 73 Grade 71 90 60 A 59 74 88 69 88 92 Average of all marks :...
