is "delete[]" necessary after a wchar_t array/ string? : As i was explaining in the title, is that necessary? or operative system just handle that?  This is the first question. The second question is from the code i was developing, i had an error from debugging with the "delete" instruction, and i'm not able to know why. When should i use delete and when i shouldn't?
