这个class'constructor/destructor有问题吗?

Is there a problem with this class' constructor/destructor?

我在未正确终止的较大函数中使用此 class。

我不得不求助于一次一个块地注释掉算法以缩小问题开始的范围。

整个事情都按照写的那样工作,但最终因错误而终止并终止了调用它的 main()

无论如何,当我实例化这个 class 时,问题就开始了。我假设它一定是析构函数的问题,当对象超出范围时导致错误。

这是 class 定义以及 constructor/destructor:

class Entry
{
    private:
        int act_count; //number of activities for generating array MUST BE DETERMINED BEFORE INSTANTIATION
        int ex_count; //number of expenditures for generating array

    public:
        Entry(int, int); // constructor
        ~Entry(); // destructor
        string date; // functions like a title
        Activity * act_arr; // pointer to an array of activities
        Expenditure * ex_arr; // pointer to an array of expenditures 
        // list of member functions
};

struct Activity
{
    public:
        string a_name;
        float time;
};

struct Expenditure
{
    public:
        string e_name;
        float price;
};

构造函数:

Entry::Entry(int a_count, int e_count)
{
    // initialization of basic members
    date = day_o_year();
    act_count = a_count;
    ex_count = e_count;

    // allocation of array space
    act_arr = new Activity[act_count];
    ex_arr = new Expenditure[ex_count];
}

析构函数:

Entry::~Entry()
{
    // prevents memory leaks when object falls out of scope and is destroyed
    delete act_arr;
    delete ex_arr;
}

这里有什么严重错误吗?我希望这不是太多的代码来引起一些兴趣。

提前致谢。

首先,我认为您需要这个(delete[] 数组):

Entry::~Entry() {
    // prevents memory leaks when object falls out of scope and is destroyed
    delete[] act_arr;
    delete[] ex_arr;
}

但除此之外,"isn't terminating properly"到底是什么意思?

问:你有堆栈 trace/core 转储吗?

问:您是否使用调试器单步执行过代码?

问:您是否有特定的错误消息可以 copy/paste 到您的 post 中?
