void quadrupler(int& n)
{
n = 4 * n;
}
int main()
{
int x[3] = {7, 8, 9};
int number = 2;
quadrupler(x[number]);
quadrupler(x[2]);
quadrupler(x[3]);
quadrupler(number);
quadrupler(x);
return 0;

Answer 1

#include <iostream>

using namespace std;


void quadrupler(int& n)


    {
    
        n = 4 * n;
    }
int main()
{
    int x[3] = {7, 8, 9};
    int number = 2;
    quadrupler(x[number]);
    quadrupler(x[2]);
    quadrupler(x[3]);
    quadrupler(number);
    quadrupler(*x);
    return 0;
}
