I would like to know for example if to allocate memory dynamically I use new [] or malloc in std :: vector, or do not need, if I do not need, where should I use new [], malloc and smartpointers?

    Sound like you could use a [good C++ book](http://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list) – NathanOliver Jun 19 '17 at 00:27

If you use c++, you would better use new [] method to allocate memory in heap because it is more safe than malloc method.

    While using `malloc` should be avoided in C++ code, if you use the STL, then you almost never should need to use `new[]` directly. – jamesdlin Jun 19 '17 at 00:57
