write this in c++ format

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;}

Write a function count_evens() that has four integer parameters, and returns the count of parameters where the value is an even number (i.e. evenly divisible by 2). Ex: If the four parameters are: 1 22 11 40 then the returned count will be: 2 Hint: Use the modulo operator % to determine if each number is even or odd. Your program must define the function:count_evens(num1, num2, num3, num4)   python # Define your function here if __name__ == '__main__':    num1 = int(input())    num2 = int(input())    num3 = int(input())    num4 = int(input())        result = count_evens(num1, num2, num3, num4)    print('Total evens:', result)

code needed

In C++: Write a function which will find the average of all elements of the sequence: {2, 4, 6, 8, 10, 12}.  Use call by reference, and return the average as the function's return value.

I would appreciate your help. I attached instructions to a C program. Could you copy and paste the code please?

in c++

Write a function that returns the greatest common divisor of 2 integers.

Write a c++ program that includes two functions for sorting integers. your program must acts as following: Ask the user to enter 5 numbers and then by calling Asc() and Dsc() functions sort these 5 numbers in ascending and descending orders. Sample output:             How many integers you wants to sort? 5             Please enter 5 integers:  5  8  -1  0   2            the ascending order of your list is:  -1   0  2  5  8             The Descending order of your list is:   8   5   2  0  -1 Note: to do the above question do not use the array , vector or class. Use swap

in the C++ version please suppose to have a score corresponding with probabilities at the end and do not use the count[] function. Please explain the detail when coding. DO NOT USE ARRAY. The game of Pig The game of Pig is a dice game with simple rules: Two players race to reach 100 points. Each turn, a player repeatedly rolls a die until either a 1 ("pig") is rolled or the player holds and scores the sum of the rolls (i.e. the turn total). At any time during a player's turn, the player is faced with two decisions: roll - if the player rolls 1: the player scores nothing and it becomes the opponents turn. 2 - 6: the number is added to the player's turn total and the player's turn continues. hold - The turn total is added to the player's score and it becomes the opponent's turn. This game is a game of probability. Players can use their knowledge of probabilities to make an educated game decision.   Assignment specifications Hold-at-20 means that the player will choose to roll…
