  bugprone-sizeof-container
  =========================
  
  The check finds usages of ``sizeof`` on expressions of STL container types. Most
  likely the user wanted to use ``.size()`` instead.
  
  All class/struct types declared in namespace ``std::`` having a const ``size()``
  method are considered containers, with the exception of ``std::bitset`` and
  ``std::array``.
  
  Examples:
  
  .. code-block:: c++
  
    std::string s;
    int a = 47 + sizeof(s); // warning: sizeof() doesn't return the size of the container. Did you mean .size()?
  
    int b = sizeof(std::string); // no warning, probably intended.
  
    std::string array_of_strings[10];
    int c = sizeof(array_of_strings) / sizeof(array_of_strings[0]); // no warning, definitely intended.
  
    std::array<int, 3> std_array;
    int d = sizeof(std_array); // no warning, probably intended.
