implement pass-by-value parameter passing method.USE C LANGUAGE
code in python program please Write a function that takes one integer parameter, makes sure it is an integer, prints sum of every two digits and return the sum of digits from the number entered by the user up to 1, using recursion.Sample input: 4 Sample output: 4+3 = 77+2 = 99+1 = 10
Write a function which takes two integer parameters for values to be added together and returns the result by value. The function may not print anything or read anything directly from the user (i.e. no cin/cout in the function). Assume that the values passed to the function will not be negative, but could be 0 or positive, and will both be integers. The function must implement addition recursively, and cannot use the standalone + operator (only ++) or call any other functions.

Is Prime Function Write a well-documented Python program, hmwk4Q1.py, that defines a function isPrime.py(N). The function accepts an integer N and returns True if N is a prime number, otherwise, returns False. Next, define the main function that asks the user for a range of numbers, say from 2 to M, and counts how many prime numbers there are within the range. Hints: Adapt your solution from Homework 2.

NB: You can not use the built in sort/sorted/max/min function. Function Call 1:Student(“Jim”,[18,20,15,12,19]) Sample Output 1:Average of Jim’s quiz marks: 18 Function Call 2:Student(“Yen”,[12 16 12 19 20 18]) Sample Output 2:Average of Yen’s quiz marks: 18.25

In this challenge, the task is to debug the existing code to successfully execute all provided test files. Python supports a useful concept of default argument values. For each keyword argument of a function, we can assign a default value which is going to be used as the value of said argument if the function is called without it. For example, consider the following increment function: defincrement_by(n,increment=1):returnn+increment The functions works like this: >>>increment_by(5,2)7>>>increment_by(4)5>>> Debug the given function print_from_stream using the default value of one of its arguments. The function has the following signature: defprint_from_stream(n,stream) This function should print the first values returned by get_next() method of stream object provided as an argument. Each of these values should be printed in a separate line. Whenever the function is called without the stream argument, it should use an instance of EvenStream class defined in…

write a python program 9. You are a class teacher at a kindergarten school. As a task, you asked your students to write a paragraph. Unfortunately, you notice that most of the students did not use capital letters correctly. Your task is to write a function which takes a string as its only parameter and returns a new copy of the string that has been correctly capitalized. Your function should: Capitalize the first letter in the string Capitalize the first letter after a full-stop, exclamation mark or question mark • Capitalize the word “i" if it is in lowercase. Summary: You have to write a function that reads a string from the user and capitalizes. The string is then returned and displayed. Sample Input ('my favourite animal is a dog. a dog has sharp teeth so that it can eat flesh very easily. do you know my pet dog's name? i love my pet very much.') Sample Output My favourite animal is a dog. A dog has sharp teeth so that it can eat flesh very easily. Do you know my pet dog's name? I…
