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 recursive C function that returns the uppercase letters of the string named str by storing them in the cap variable. The prototype of the function should be: void F (char * str, * char cap); we use devC ASAP

Write a C++ recursive function int fib(int n) that returns the value of the n’th Fibonaccinumber . Do not use a loop. Test it in the main program, not in the function.The Fibonacci sequence is0 1 1 2 3 5 8 13 21...Each Fibonacci number is the sum of the preceding two Fibonacci numbers.

Explain in detail how this recursive function works: Program description: The program counts then number of 7's in a number C++ code: #include <iostream>using namespace std;//definig numSevens functionint numSevens(int s){//checking if number is 0if(s==0)//returning 0return 0;//checking if last digit is 7else if(s%10==7)//returning 1 and recursively calling numSevens function for the next digitreturn(1+numSevens(s/10));else//returning 0 and recursively calling numSevens function for the next digitreturn(0+numSevens(s/10));}int main(){//calling numSevens function for a sample value and printing resultcout<<numSevens(47364778)<<endl;return 0;}

1) Write a recursive void function that has one parameter that is a positive integer and that writes out that number of asterisks (*) to the screen, all on one line. How do I do this in python?

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...

In c++ please help me answer this question I will give you a good rating :) implement the three versions of the addupto20() function: iterative, recursive, and divide-and-conquer approach test these functions with a few inputs from your main() Iterative solution * check if there exsits two numbers from vector data that add up to 20 e.g., if data=[2,5,3,15], the function returns true, as data [0] +data [3]==20 e.g., if data=[3,4,0,8], the function return false precondition: vector data has been initialized postcondition: if there are two numbers from list add up to 20, return true; otherwise, return false */ bool AddupTo20 (const vector‹int> & data){ } Come up with a recursive solution to the problem, following the hints given below: * check if there exsits two numbers from vector data[first...right] add up to 20 e.g., if data=[2,5,3,15], first=0, last=3, the function returns true, as data [0] +data [3]==20 e.g., if data=[2,5,3,15], first=2, last=3, the function returns...

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) { }

Please answer in c++

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.

*In C program, what is wrong with the following function? int integer_add( int x, int y, int z ) { int sum; sum = x + y + z: return sum; }

1. You are to create a well-formed Python recursive function (i.e, there must be a stopping/base case and the recursive case must present a smaller problem), along with a call to that function. 2. Trace your function and call. Remember that you must keep track of memory for each function call and provide output. How would I trace a function? and keep track of its memory for each function call?

Below, enter code to complete implementation of a recursive function palindrome() that determines whether an input string is a palindrome or not: 3. palindrome(s):
