Member fields, order of construction

Question

In C++, when doing something like what you see below, is the order of construction guaranteed?

Logger::Logger()
    : kFilePath_(\"../logs/runtime.log\"), lo         


        

Answer 1

The order of construction is the order of declaration in the class definition.

If the ordering in the ctor-initializer differs, this does not affect the order of construction. Your compiler may warn on this.

See 12.6.2/5 (2003 wording, named [class.base.init]):

nonstatic data members shall be initialized in the order they were declared in the class definition (again regardless of the order of the mem-initializers).
