Warning this will be initialized after that

[Christopher]

What causes this kind of warning to occur? why is the compiler forcing
some order of initialization in an initializer list?
I frequently run into this when I am initializing a pointer and an int
in a constructor's initializer list.

The language requires that sub-objects (bases and data members) are
initialized in the order they are declared. The order specified in an
initializer list does not matter. A compiler may warn you that you will
not get the order you have used in an initializer list.

To avoid such warnings, use the declaration order in every initializer list.

Class members are initialised in the order they are declared, not the
order they appear in initialiser lists.
