为什么会发生访问冲突

Question

#include<iostream>

using namespace std;

class Carlo
{
private:
    double weight;
    double price;
    static double all_weight;
    static double all_price;
public:
    Carlo(double w, double p);

double Carlo::all_weight = 0;
double Carlo::all_price = 0;

Carlo::Carlo(double w, double p)
{
    weight = w;
    price = p;
    all_weight += weight;
    all_price += price;
}
Carlo::~Carlo()
{
    all_weight -= weight;
    all_price -= price;
}
void Carlo::printCarlo()
{
    cout << weight << "kg " << price << "yuan" << endl;
}
void Carlo::printAllCarlo()
{
    if(fabs(all_weight)<1e-8&& fabs(all_price) < 1e-8)
        cout << 0 << "kg " << 0 << "yuan" << endl;
    else
        cout << all_weight << "kg " << all_price << "yuan" << endl;
}

int main()
{
    Carlo* g1 = new Carlo[3]{ Carlo(3.2,5.8),Carlo(6.6,3.52),Carlo(7.1,3.79) };
    for (int i = 0; i < 3; i++)
    {
        g1[i].printCarlo();
    }
    Carlo::printAllCarlo();
    Carlo* g2 = new Carlo(9, 8);
    g2[0].printCarlo();
    Carlo::printAllCarlo();
    delete[]g1;
    Carlo::printAllCarlo();
    delete[]g2;
    Carlo::printAllCarlo();
}

Answer 1

测试过了，delete[]g2;错了，改为delete g2;，因为你是Carlo* g2 = new Carlo(9, 8);，new单个的
