In this, it can access private and public members of the class. WebGCC automatically inlines member functions defined within the class body of C++ programs even if they are not explicitly declared inline.

Other languages check the types and look for type errors during runtime. Those have dynamic typing. Another way to think about it: static typing means checking the types before running the program, dynamic typing means checking the types while running the program.
