Answer:
The program in C++ is as follows:
#include <iostream>
#include <vector>
using namespace std;
int main(){
vector<int> nums;
int num;
cin>>num;
while(num != -1){
nums.push_back(num);
cin>>num; }
for (auto i = nums.begin(); i != nums.end(); ++i){
cout << *i <<endl; }
return 0;
}
Explanation:
This declares the vector
vector<int> nums;
This declares an integer variable for each input
int num;
This gets the first input
cin>>num;
This loop is repeated until user enters -1
while(num != -1){
Saves user input into the vector
nums.push_back(num);
Get another input from the user
cin>>num; }
The following iteration print the vector elements
<em> for (auto i = nums.begin(); i != nums.end(); ++i){
</em>
<em> cout << *i <<endl; }
</em>

Explanation:
Given
The attached function
What the recursion does is that; it adds up individual digits from N to 0
Solving (a): Each output when N = 6
For N = 6.
The function returns the following values:
f(6) = 6
Then: 6 + f(5)
Then: 6 + 5 + f(4)
Then: 6 + 5 + 4 + f(3)
Then: 6 + 5 + 4 + 3 + f(2)
Then: 6 + 5 + 4 + 3 + 2 + f(1)
Then: 6 + 5 + 4 + 3 + 2 + 1 + f(0)
Then: 6 + 5 + 4 + 3 + 2 + 1 + 0 = 21
Solving (b): The output when N = 7
Using the same process in (a) above.
The output is 28
