- - - - declarate
      - identifier
      - Lvalues
        
        expressions that refer to a memory location
        
        Rvalues
        
        refers to a data value that is stored at some address in memory
    - - number contants
        
        integer
        
        int, long int => L, l
        
        unsigned int => U, u
        
        floating point
        
        double, float => F, f
        
        long double => L,l
      - for value which will not change
      - define constant
        
        using #define preprocessor
        
        ex.
        
        #define identifier value
        
        using const keyword
  - - - declare a variable at any place
    - - used to define local variables that should be stored in a register instead of RAM
    - - instructs the compiler to keep a local variable in existence during the life-time of the program instead of creating and destroying it each time it comes into and goes out of scope
      - class members
        
        it causes only one copy of that member to be shared by all objects of its class
    - - applies only to class objects
      - mutable members can be modified by const member function
  - - - math. opemations are in lib. cmath
    - - increment
        
        --x x--
      - +x -x
      - decrement
        
        ++x x++
    - - static_cast< type > ( expression )
      - dynamic_cast< type > ( expression )
    - - = <<= ^= &= |=
    - - == != < > <= >=
    - - && || !
    - - sizeof #
      - member operator
        
        .(dot)
        
        -> (arrow)
        
        to access the members of a structure using a pointer to that structure
      - casting operators

    - - rules
  - - - public
      - private
      - protected
        
        protected member variable or function => can be accessed in child classes which are called derived classes

        at least one of its functions as pure virtual function
