5. The equality operator is represented by
:= .EQ. = ==
6. Operators have hierarchy. It is used to know which operator
is most important is used first is faster operates on large
numbers
7. The bitwise AND operator is used for
Masking Comparison Division Shifting bits
8. The bitwise OR operator is used to

set the desired bits to 0
divide numbers multiply numbers
9. Which of the following operator has the highest precedence?
* == => +
10. The associativity of ! operator is
Right to Left Left to Right (a) for Arithmetic (a) for Relational
and (b) for Relational and (b) for Arithmetic
11. Which operator has the lowest priority?
++ % + ||
12. Which operator has the highest priority?
++ % + ||
13. Operators have precedence. A Precedence determines which operator is
faster takes less memory evaluated first takes no arguments
14. Integer Division results in
Rounding the fractional part
truncating the fractional part
Floating value An Error is
generated

5 6 11 None of these
17. The type cast operator is
(type) cast() // " "
18. Explicit type conversion is known as
Casting Conversion Disjunction Separation
19. The operator + in a+=4 means
a = a + 4 a + 4 = a a = 4 a = 4 + 4
20. p++ executes faster than p+1 because
p uses registers p++ is a single
instruction ++ is faster than + None of these
