To be Modern or Not

C++ has great change after C++11 and it still continues. I shared some of the basic important topics before. But I wish to add a summary here ;

• Use nonstatic data initialization instead of the old way. (Why nonstatic data initialization is important)
• Delete unused constructors with delete keyword.
• If you wish your compiler overcome a constructor method, Default keyword helps you
• Delegating parameters to parent method or a term which is a member of the class so easy in modern.
• Every time try to provide copy constructors.
• Copy constructor not enough! add a move constructor.
• std::move is your new helper.
• Never use c-type casketing.
• Always use smart pointers.
• Prefer unique_ptr if your pointer won’t be to pass an argument
• Shared_ptr is the best way if you pass a pointer.
• Use weak_ptr to reach counter pointer of shared pointers.
• Use enum class instade of the old enum type.
• To create a function which runs on compile-time learn constexpr
• Initializer_List basic list type which is generated by the compiler.
• using keyword is the way to implement constructors of inheritance.
• Default virtual methods are 0.
• Write all method in virtual if you wish to overload on the child.
• Final is the way to stop this override process.
• Never forget the overload keyword.
• Virtual classes important on Dimond inheritance
• You can’t throw an exception from deconstruction method.
• Template is important
• Non-type templates include the size of arrays
• Learn how to forward a parameter
• The variadic template uses stf:forward
• Lambda is everyting
• Lamdas are function objects
• Learn concurrency
• Mutex is the way to protect variable
• Atom is the new memory model

I hope it helps
