c++ - 内存堆问题C++，动态分配多维数组

Question

我正在从以下 C++ 脚本中获取内存堆消息。如果我删除数组释放，错误就会消失。所以这个错误可能在代码的释放部分。我想不通

if(harmonic_type =='a')
{
    double ** harmonic_content = new double *[number_of_harmonics_required_to_monitor](); 
    for (int i=0;i<number_of_harmonics_required_to_monitor+1;i++) 
    {                                                           
        harmonic_content[i] = new double [2]();                 
    }
    harmonic_content =  harmonic_detector(waveformdata,number_of_samples,samplingrate_Hz, fundamental_frequency_Hz, number_of_harmonics_required_to_monitor,harmonic_type);

    for (int i=1;i<number_of_harmonics_required_to_monitor+1;i++)
    {                                   
        cout<<" Harmonic order "<< i << "::::" << harmonic_content[i][0] << " Hz ::::"<<harmonic_content[i][1] << " :::: "<<harmonic_content[i][2]<<endl;
    }

    for (int i=0;i<number_of_harmonics_required_to_monitor+1;i++) 
    {   
        delete [] harmonic_content [i];                 
    }
    delete [] harmonic_content;
}

Answer 1

在

    new double *[number_of_harmonics_required_to_monitor]()

创建的元素总数:number_of_harmonics_required_to_monitor

在

    for (int i=0;i<number_of_harmonics_required_to_monitor+1;i++)

写入的元素总数:number_of_harmonics_required_to_monitor+1(从 0 到 number_of_harmonics_required_to_monitor)

在

    for (int i=1;i<number_of_harmonics_required_to_monitor+1;i++)

最后读取的元素不存在:它具有索引 number_of_harmonics_required_to_monitor+1
