The following conditional expression is written in the C language. It is true when the value of the variable a is outside the range of 20 to 30 (including end points) and false otherwise:
!(a < = 20 && a > = 30)
Which of the following conditional expressions is equivalent?
a) a>20 &&a<30
b) a<20 &&a>30
c) a>=20 &&a<=30
d) a>20 Ha<30
e) a < = 20 II a > = 30
f) a<20 Ila>30
d) a>20 Ha<30
Approach: Remove the not operator (!)
Flip applicable relational operators (< = becomes > and > = becomes <)
Flip applicable logical operators (&& becomes II)
