Question

我有一个主函数，可以在for循环中创建类模拟的实例，并且在模拟的构造函数中，有一个for循环，它创建指向 Populations 的指针实例。

我的问题是，从输出中，我知道模拟的构造函数完成了对 Population * 的向量的推回，但它似乎不是真的离开构造函数，因为main中的for循环不会继续。非常感谢你！

主要：

的摘录

std::vector<Simulation> openSimulations ; 
       for(size_t i(0) ; i < n ; ++i)
       {
           std::cout << "Rounds that should be completed : " << n << std::endl ; 
           std::cout << "Stuck 3 !" << std::endl ;
           openSimulations.push_back(Simulation(f, n, t, p, M, m)) ;
           std::cout << "Finished adding!" << std::endl ; 
       }

的摘录

Simulation::Simulation(std::vector<double> pInitialFrequencies, int pPopSize, 
        int pGenerationNumber, int pPopulationNumber, bool pMigration,
        double pMigrationProbability )
:myGenerationNumber(pGenerationNumber), migration(pMigration),
    myMigrationProbability(pMigrationProbability)
{
    std::cout << "Stuck 6 !" << std::endl ;
    for(int i(0) ; i < pPopulationNumber ; i++ )
    {
        myPopulations.push_back(new Population(pInitialFrequencies,
            pGenerationNumber, pPopSize,  myMigrationProbability)) ;
        std::cout << "Stuck 7 !" << std::endl ;
    }

    std::cout << "Have exited or loop in Simulation::Simulation!" << std::endl ;

}

这是我在终端的输出：

各位大家好，我找到了自己问题的答案！

模拟的析构函数不正确。

使用这样的析构函数，它现在可以工作：

Simulation::~Simulation()
{
    for(auto population: myPopulations)
    {
        population = nullptr ;
        delete population ;
    }
}

我会在这里留下问题，以防任何人遇到同样的问题。
