这个问题试图收集每年出版的数十本不良C++书籍中的少数珍珠.

与许多其他编程语言不同,这些编程语言经常从互联网上的教程中随处获取,很少有人能够快速学习C++,而无需学习编写精良的C++书籍.这样做太复杂了.事实上,它是如此庞大和复杂,有很多非常糟糕的C++书籍.我们并不是在谈论糟糕的风格,而是体育明显的事实错误和促进糟糕的编程风格.

请编辑接受的答案,以提供高质量的书籍和近似的技能水平 - 最好 在 C++聊天室讨论您的添加后.(如果他们不同意建议,常客可能会毫不留情地撤销你的工作.)添加一篇关于你亲自阅读/受益的每本书的简短描述/描述.随意讨论质量,标题等.符合标准的书籍将被添加到列表中.由C和C++用户协会(ACCU)撰写评论的图书都有指向评论的链接.

我在我的代码中使用向量

    std::vector<CEventLogInfo >

    class CEventLogInfo 
    { 
      // date and time
  unsigned short    m_sMonth;
  unsigned short    m_sDay;
  unsigned int  m_nYear;
  unsigned short    m_sHour;
  unsigned short    m_sMin;
  unsigned short    m_sSec;

  unsigned long m_nGatewayMacID;
  unsigned char m_byCommandType;
  unsigned char m_byStatus;
  unsigned char m_byEventName;
  unsigned char m_byDirection;
  unsigned short    m_nPacketLen;
  char*         m_pPacket;
     // ..some method 
 }
 CEventLogInfo::CEventLogInfo(const CEventLogInfo& refMessage)
 {      
m_sMonth        = refMessage.m_sMonth;
m_sDay          = refMessage.m_sDay;
m_nYear         = refMessage.m_nYear;
m_sHour         = refMessage.m_sHour;
m_sMin          = refMessage.m_sMin;
m_sSec          = refMessage.m_sSec;

m_nGatewayMacID = refMessage.m_nGatewayMacID;
m_byCommandType = refMessage.m_byCommandType; …

我试图用称为细胞的对象填充二维向量(817乘577).这些单元格具有一组成员值(浮点数,其他向量等).在某个时刻程序停止并抛出错误"vector<T> too long".这是单元格的类定义和完整的循环:

struct cell
    {
    int x;
    int y;
    int country;
    vector<int> popO;
    vector<int> popS;
    vector<float> Rainfall;
    double Cropland;
    vector<movement> outm;
    vector<movement> inm;
    vector<double> AgeMaleFemale;
    vector<double> AgeMaleFemaleMortality;
    double Fertility;
    };
vector<vector<cell>> cells;
void fillCells(dataserver D)
        {
        cout<<"start filling"<<endl;
        int rows=577;
        int columns=817;
        cell X;
        vector<vector<cell>> output(rows,vector<cell>(columns,X));
        cout<<"start loop"<<endl;
        for (int i=0;i<rows;i++)
            {

            for (int j=0;j<columns;j++)
                {

                tmpC.popO.resize(3,0);
                tmpC.popO[0]=int(D.PO[0][i][j]);
