Question

**C++**

Given three function parameters p1, p2, p3, rotate the values to the right. Rotate means to shift each item to the item on the right, with the rightmost item rotating around to become the leftmost item. If initial values are 2 4 6, final values are 6 2 4. HINTS Declare the function's three parameters as reference type. Function return type is void. Use a tmp variable in the function (similar to when swapping two variables). Your first assignment statement in the function should be assigning tmp with one of the three parameter's value. Be careful not to overwrite a value that you expect to use. The order in which you do the assignments matters.

Answer 1

#include <iostream>

using namespace std;

void RotateRight3(int &n1, int &n2, int &n3) {
    int tmp = n3;
    n3 = n2;
    n2 = n1;
    n1 = tmp;
}

int main() {
    int n1, n2, n3;

    cin >> n1;
    cin >> n2;
    cin >> n3;

    RotateRight3(n1, n2, n3);

    cout << n1 << " " << n2 << " " << n3 << endl;

    return 0;
}
