Write a recursive function diff which takes two positive integer arguments (x and y) and returns |x – y|. You may not perform an x - y calculation anywhere in the function! Example calls: diff(3, 7) returns 4; diff(7,3) returns 4   In JAVA

In C programming: Write a function printAllCourses() which receives an array of course pointers and the array’s size, then prints all courses in the array by calling printCourseRow()

Name:- Mit (Question-1) Note:- Please type this java code and also need an output for this given Java program.

Functions like print which perform an action but don’t return a value are called: Select one: a. recursive functions b. built-in functions c. simple functions d. utility functions e. void functions

c programming Task 3: Complete armstrong_task3.c by implementing armstrong_recursive function. int armstrong_recursive (int arm); It performs same operation as in Task 1, however in a recursive manner. A number to be checked whether it is armstrong or not is given as an input and the function returns the summation of the digits. If the returned value is equal to the given input value then it is an armstrong number.

8. using c++, Write a function method that determines the mean of all the values in an array of integers. Your mean function should call a separate function that you write that determines the sum. Don’t use built-in sum or mean gadgets, but roll your own.

Scenario: I am trying to create a recursion function that takes a number from the user. That number then goes through to equations where it squares the number and takes the square root of it. Then, that value is supposed to be sent back through the function, through the same equations. Then, I am trying to output the value of each iteration. The amount of iterations is a random number. This code is in C++ and I am using Visual Studio 2023. I have attached the code I, myself, typed and picture of the output. Also, this is a header file that is being called from my source.cpp file (case 5 in switch case). That is why I am entering 5 as the first input when I run the program. Problem: The output only shows one iteration of calculation, then goes straight back into taking an input from the user. What am I doing wrong?
