I'm having trouble converting malloc from my c code to c++ way of using new. I've also read about using std::vector for dynamic memory allocation. Which one is better for my case and how would you do this properly? Current code: matrix_t * matrix = (matrix_t *) malloc(sizeof(mat...
When you add a new element at the end of the vector, it increases the container size by one, which causes an automatic reallocation of the allocated storage space. If a reallocation happens, all iterators, pointers and references related to the container are invalidated. Otherwise, only the en...

比如vector一般拥有一段动态申请的内存。那么 vector<int> a;func(move(a));就告诉func函数，a的内容...
This approach is more efficient than having a separate std::vector for buffer allocation, with a separate dynamic memory allocation, and then a deep-copy into the std::wstring.However, note that overwriting the NUL terminator in STL strings with another NUL terminator seems to be "undefined ...

It dies when deallocating the vector, in the xutility's inline void __CLR_OR_THIS_CALL _Container_base::_Orphan_all() call. The full message is: Unhandled exception at 0x104817fd (msvcp80d.dll) in OptDot.exe: 0xC0000005: Access violation writing location 0x137a16d8. I have been ...
std::wstring Convert2WString (int From) { wchar_t buffer[20]; _itow_s (From, buffer, sizeof (buffer) / sizeof (wchar_t), 10); return std::wstring (buffer); } You will need perhaps add a little error-handling. Also, you will need to fix GetVariable to accept a std::wstring ...
