2. Conditional Expressions

Conditional and Logical Operators: operands are any basic type, result is 0 or 1

Table is in decreasing order of precedence, associativity is left-to-right for all except !

Math/ Logic	C
NOT	!
<	<
≤	<=
>	>
≥	>=
≡	==
≠	!=
AND	&&
OR	||

Expressions:

  Math                C                      same as
  ----                ----                   -------
  x+y ≥ 9.1           x+y >= 9.1             (x+y) >= 9.1

  5 < a < 10          5 < a && a < 10        (5 < a) && (a < 10)

  |k| ≥ 3             fabs(k) >= 3           !(fabs(k) < 3)

  a ≡ b ≡ c           a == b && b == c       (a == b) && (b == c)

  NOT A AND B OR C    !A && B || C           ((!A) && B) || C
