Miscellaneous-MissingConstructor

Each class needs an explicitly declared constructor

Required inputs: IR

If a class does not have an explicitly declared constructor, the C++ compiler will generate a default constructor. The compiler-generated default constructor will leave POD fields uninitialized, which may cause undefined behavior if the class is used without proper initialization.

Rule GeneralPurpose-InitializeAllFieldsInConstructor ensures that constructors do not leave fields uninitialized.
