Learn About How To Use Non-static Data Member Initializers For Windows Apps In C++

Embarcadero Bcc32c and bcc32x (Clang-enhanced compiler for Win32) implements all of the ISO C++11 standard. It includes the use of non-static data member to be initialized where it is declared. The basic idea for C++11 is to allow a non-static data member to be initialized where it is declared (in its class). A constructor can then use the initializer when run-time initialization is needed.

Why useful.
-Easier to write.
-You are sure that each member is properly initialized.
-You cannot forget to initialize a member like when having a complicated constructor. Initialization and declaration are in one place – not separated.
-Especially useful when we have several constructors.
-Previously we would have to duplicate initialization code for members.
-Now, you can do a default initialization and constructors will only do its specific jobs.

If a member is initialized by both an in-class initializer and a constructor, only the constructor’s initialization is done (it “overrides” the default).
