The results:
Input the vector number:9
Put the 4 and 4on the balance.
Put the 4 and 4on the balance.
Put the 4 and 2on the balance.
The weight of is fake coin.is2
The codes:
#include <iostream>
#include <vector>
using namespace std;
void fill_vector(vector<double> &quantity, int n);
double find_fake_coin(vector<double> quanity, int n);
int main()

cin >> number;
vector<double> quantity;
fill_vector(quantity, number);
//cout << quantity[4];

cout << "The weight of " << "is fake coin.is" << fake_coin_weight;
return 0;
}
void fill_vector(vector<double> &quantity, int n)
{
