The lines of code. We should not access non-static member inside static function.As we can call static function with scope resolution operator coincide it it won’t know for which object it should change the value of non static variable.
Difference between Linux OS and windows.
Difference b/w value by & reference by
Class: static members exist as members of the class rather than as an instance in each object of the class. So, this keyword is not available in a static member function. Such functions may access
only static data members. There is only a single instance of each static data member for the entire class:
A static data member : class variable
A non-static data member : instance variable
Static member function: it can only access static member data, or other static member functions while non-static member functions can access all data members of the class: static and non-static.

system level programming: Systems programming, is the activity of programming computer system software. The primary distinguishing characteristic of systems programming when compared to application programming is that application programming aims to produce software which provides services to the user directly (e.g. word processor), whereas systems programming aims to produce software and software platforms which provide services to other software, are performance constrained, or both (e.g. operating systems, computational science applications, game engines, industrial automation, and software as a service applications).[1]

Json: JSON is perfect for storing temporary data. For example, temporary data can be user-generated data, such as a submitted form on a website. JSON can also be used as a serialization data format for any programming language to provide a high level of interoperability.
