a. Write a function named count Digits that accepts a positive integer as its parameter and returns the number of digits in that number. For example, countDigits(8546587) should return 7. You may assume that the value passed to your method is non-negative. the number 8546587 has seven digits, so the call b. Write a program to input an integer n and call the above function in part a if n is positive, else give 'Value must be Positive' message. Inputting will stop when 0 is entered.

Write a set of functions that calculate the cost of movie tickets for a family.   Using a loop, keep asking: The age of the movie goer. Based on this age, you will charge them these amounts: Under age 3, the ticket is free. If they are between 3 and 12, the ticket is $10.25. If they are over age 12, the ticket is $15.50. If they are 55 or older, the ticket is $12. If they buy at least 4 tickets, they receive a 20% discount. Then, keep a running_total that is output to the screen after each age has been entered. This running_total should be accessed through the functions using a pass-by-reference variable:   &running_total The other function parameter variables are to be pass-by-value. Tell them to enter a zero when they want to stop.   Finally, calculate the total cost including a 7.5% sales tax. and output it to the screen.   Be sure that the code is broken up into functions with good comments. Put as little code in main() as you can get away with and still make sense.…

use c code to Develop a function that gets two same length strings as parameters and reports the number of characters that they have different. For example, if the two strings are   Str1: “Hello world! Happy Friday”Str2: “Hello Johny! happy friday”   The function should return: Your strings are different in 7 places However, if the strings are exactly equal, it should just say Your strings are the same   If the strings are not of the same length, the code should just say: The two strings are not of the same length!   Hint: 1.compare the two strings character by character and report the differences 2.answer must have and show the output

Write a function “gcDivisor” that takes two positive int “k” and “m” and returns the greatest common divisor of these two positive integers. Using recusion in python3.

Please answer it in Python Write a function division_arrondi that takes as an argument a numerator, a denominator, and as optional arguments a rounded Boolean  (worth False by default) and a decimal integer  (valid 0 by default) and that calculates the value of the numerator/denominator fraction (unless the denominator is zero, in which case your function will display an error message and return nothing). If the rounded Boolean is False, the function will return this result without rounding it (if decimales is specified during the call, it will be ignored). If the rounded Boolean  is True, the result will be rounded to the requested number of decimal places (by default, to the nearest integer). To make your rounds, you will use round(nombre_a_arrondir, nombre_de_decimales). Examples:division_arrondi(1,3) is 0.333333333333333333 division_arrondi(1,3,rounded=True, decimales=2) is 0.33 division_arrondi(15,8) is 1,875 division_arrondi(15,8, True) is 2 division_arrondi(15,8, rounded=True,…
