      When using C++, you should always strive to use STL containers like std::vector and std::list instead of ordinary C arrays.

      Consider this example:

      All is fine, until doSomething() is changed to throw an exception. If doSomething throws, we will have a memory leak.

      The correct way of doing this is:

      If doSomething() throws an exception now, no memory will be leaked.

      This is just one of the reasons to use STL containers instead of C arrays. STL containers are much less error prone, more robust and easier to use.
