删除数组指针？

如何删除已经分配给数组的内存models, names？我尝试了所有方法，但运行时总是崩溃。

int main()
{

    vector<Person*> people;

    const int PERSON_SZ = 4;
    char * names[] = {"Jim", "Fred", "Harry", "Linda"};
    int ages[] = { 23, 35, 52, 59 };

    for (int i = 0; i < PERSON_SZ; i++)
    {

        Person * temp = new Person(names[i], ages[i]);
        people.push_back(temp);
    }

    // A vector of Car pointers
    vector<Car*> cars;

    const int CAR_SZ = 3;
    char * models[] = { "Festiva", "Ferrarri", "Prius" };
    srand(time(0));
    for (int i = 0; i < CAR_SZ; i++)
    {

        Car * temp = new Car(models[i]);
        temp->set_driver(people[rand() % (people.size())]);
        temp->set_owner(people[rand() % (people.size())]);
        cars.push_back(temp);
    }



    for (int p = 0; p < people.size(); p++)
    {
        people[p]->increment_age();
    }

    for (int c = 0; c < cars.size(); c++)
    {
        cars[c]->print();
    }

    delete [] names;
    for ( int r = 0; r < CAR_SZ; ++r )
       {
           delete [] models[r];
       }
    return 0;
}

你没有分配models and names using new，所以你不能delete them.

两个数组都在堆栈上分配，并在函数返回时自动删除。

（字符串）数组的内容（即字符串本身）存储在全局数据段中，根本无法释放。这也很危险，因为编译器可能在程序的不同位置使用相同的字符串常量。
