Review OOP244 - Primitive types & Derived Types

Both C and C++ predefine all of their primitive types. We cannot redefine these types or introduce new primitive types.
int,double,float,char

derived types
struct Type{
...
};

 struct Student {
  int no;          // student number
  char grade[14];  // grades
};

struct Student harry;

to access harry's student number, we write

harry.no;


to get address of harry's student number, we write

&harry.no;

//&harry.grade[0];

We retrieve the address of a non-array member using the address of operator (&)

&instance.member
