改成std::vector<CString>则几百个都没有出现问题。 出现问题的代码类似: ... GetWinDir(cWinDir);if(cWinDir.IsEmpty()) {++nCount;continue; } cWinDir+=lpszFilePath; cWinDir+=lpszFileName;//check if file exist, if not add it to fix_listif(!(pThis->DoesFileExist(cWinDir.GetBuffer())...

However, what makes this case different than the previous example is that the temporary is going to be destroyed anyway. After initialization is complete, the temporary doesn’t need its data any more (which is why we can destroy it). We don’t need two sets of data to exist simultaneousl...
C++ std::vector 一维 二维数组 初始化 为0 一维 vector<int>(列数, 0); 二维 vector<vector<int>> newOne(行数, vector<int>(列数, 0));
This is one of the warts of C++ initialization:{ 10 }will match a list constructor if one exists, or a single-argument constructor if a list constructor doesn’t exist. This means which behavior you get depends on whether a list constructor exists! You can generally assume containers have ...
The following code does not build with the latest MSVC (17.9.6). If one of the two import statements is removed, the code builds, but if both exist they collide and create compilation errors. import std; import <vector>; int main(){ ...
