  unsigned int i = 7;
  const double d = 5.7;
  char* str[] = {"This", "is", "a", "string", "array"};
  extern short int ei;
  bool is_even(int a);
  Point p1(1,2);
  Pair q1 = {3,4};

Base type
Declarator
- The name being declared
- Optional declarator operators - mimics their use as operators in expressions
Specifier:
- Storage class: auto, extern, mutable, register, static, virtual
Initializer
- Assignment-like
- Function-like
- Universal (C++11)
