Write a recursive function in C++ to multiply all even numbers from 2 to n, where n is an input to the function, and n>=2.

Please IN C++ Write the simplest program that will demonstrate iteration vs recursion using the following guidelines -  Write two primary helper functions - one iterative (IsArrayPrimeIter) and one recursive (IsArrayPrimeRecur) - each of which Takes an array of integers and its size as input params and returns a bool such that 'true' ==> all elements of the array are prime, so the array is prime, 'false' ==> at least one element in array is not prime, so array is not prime.  Print out a message "Entering <function_name>" as the first executed statement of each function. Perform the code to test whether every element of the array is a Prime number. Print out a message "Leaving <function_name>" as the last executed statement before returning from the function. Remember - there will be nested loops for the iterative function and there can be no loops at all in the recursive function. For the recursive function - define one other helper function (IsPrimeRecur) which…

SML programming Write a recursive function np(n) which takes a non negative n and  generates a list of numbers from n+1 down to 0. You may assume that input of n is always valid. Must use identical function name and parameter(s). np(4)⟶[5,4,3,2,1,0]

In C++ Consider the following recursive function (Chapter 17, #9, modified)   void recFun(int x) {       if (x > 10)       {            recFun(x / 10);            cout<< x % 10;       }       else            cout<< x; }   How can the code be modified so that the sum of all digits is printed?

write a c++ recursive function to solve the following: str contains a single pair of parenthesis, return a new string // made of only the parenthesis and whatever those parensthesis contain. You can use substr in this problem. // // Pseudocode Example:// findParen("abc(ghj)789") =&gt; "(ghj)" // findParen("(x)7") =&gt; "(x)" // findParen("4agh(y)") =&gt; "(y)" // string findParen(string str) { }

In C++: Explain and show how to use the recursive function int gcd (inta, int b).

2. Consider the following function: def func1(n): output = 1 for i in range (1, n) : output = i return output Rewrite the function as a recursive function.

in c++ with pre and post pseudocode please dont show me the same code from others please thank u Write the simplest program that will demonstrate iteration vs recursion using the following guidelines -  Write two primary helper functions - one iterative (IsArrayPrimeIter) and one recursive (IsArrayPrimeRecur) - each of which Takes an array of integers and its size as input params and returns a bool such that 'true' ==> all elements of the array are prime, so the array is prime, 'false' ==> at least one element in array is not prime, so array is not prime.  Print out a message "Entering <function_name>" as the first executed statement of each function.

Write a recursive function definition in C that will calculate the sum of the first n odd integers (all odd interfere between 1 and 2n - 1)

Suppose a recursive function f(n+1)=f(n)+3 and f(3)=10. What is the value of f(5)
