我有以下列表:

['t','e','s','t','s','t','r','i','n','g']

如何每个字符串后面添加空字符t,e,s,t,s,t,r,i,n,g？

我使用Visual Studio 2005

当我编译时,我收到此错误:

错误1错误C2146:语法错误:缺少';' 在标识符"mDropEndTime"之前

错误2错误C4430:缺少类型说明符 - 假定为int.注意:C++不支持default-int

struct MB_SYN_DROPITEM_UPDATE : MSGBUF
{
    long                    mCid;           // Index
    unsigned long           mItemIdx;       // idx
    TIMESTAMP_STRUCT        mDropEndTime;   // This is error line
};

为什么C++不知道TIMESTAMP_STRUCT？

我正在开发一个共享项目.我有一些标识符错误,VS C++ 2005不知道CRITICAL_SECTION和LPCRITICAL_SECTION.

LPCRITICAL_SECTION GetReadCS() { return &m_ReadCS; }
LPCRITICAL_SECTION GetWriteCS() { return &m_WriteCS; }

和

CRITICAL_SECTION    m_ReadCS;
CRITICAL_SECTION    m_WriteCS;

并有一些错误

warning C4183: 'GetReadCS': missing return type; assumed to be a member function returning 'int'
warning C4183: 'GetWriteCS': missing return type; assumed to be a member function returning 'int'
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
error C2146: syntax error : missing ';' before identifier 'm_WriteCS'

为什么LPCRITICAL_SECTION和CRITICAL_SECTION未定义？我怎样才能让C++知道它？
