Chapter 4

1) Arithmetic operators :

    + + (Unary Plus)

    - - (Unary minus)

    + (Addition)

    - (Substraction)

    * (multiplication)

    / (Floating-point division / Integer division)

    % (Modulus)

Dlm C++, ade increament nan decrement operator..

    + + (Pre-increment) e.g + +m

    + + (Post-increment) e.g m+ +

    - - (Pre-decrement) e.g - -n

    - - (Post-decrement) e.g n- -

Tips utk sng hfl : klw simbol dy tuh kt dpn variable (Pre-), kne tambah or tolak nan 1.. tp klw simbol kt blkng (Post-) xyah tmbah pape.. ekot jek mcm soklan dy.. aq bg cth k..

SOALAN :        a = 2 , b = 3

                      m = 2 , n = 3

                       p = 2 , q = 3

                       x = 2 , y = 3            

(+ + a) + (- - b) * 4 > (+ + m) * (- - n) + 4

JAWAPAN :

               

2) Relational operators :

    < (Less than)

    > (Greater than)

    = = (Equal to)

    < = (Less than or equal to)

    > = (Greater than or equal to)

    ! = (Not equal to)

3) Logical operators : (0/False , 1/True)

    & & (AND) ----> ade je 0 mesti 0/false

    | | (OR) ----> ade je 1 mesti 1/true

    ! (NOT) ---->

    !(& &) (NOT AND) ---->

    !(| |) (NOT OR) ---->  | |
