Operators, C#.NET

Operators

Question: Which of the following is a compound assignment operator?
A
=+

B
+=

C
==

D
!=

Note: Compound assignment operators perform an operation and assignment in one step.
1. Report
Question: What does the << operator do?
A
Performs bitwise left shift

B
Performs bitwise right shift

C
None

D
Both

Note: The << operator shifts bits to the left, effectively multiplying the number.

Question: What is the output of 0 | 1?
A
1

B
0

C
2

D
3

Note: The bitwise OR operation results in 1 (binary 00 | 01 = 01).
1. Report
Question: What does 5 > 3 && 2 < 4 evaluate to?
A
true

B
false

C
null

D
error

Note: Both conditions are true, making the result true.
1. Report
Question: Which operator checks if two operands are not equal?
A
!=

B
==

C
=!=

D
<>

Note: The != operator checks for inequality.
1. Report
Question: What does b >>= 1 do?
A
Divides b by 2 and assigns the result to b

B
Multiplies b by 2 and assigns the result to b

C
None

D
Both

Note: The right shift operator divides the value by 2 for each shift.
1. Report
Question: What is the result of 3 + 4 * 2?
A
14

B
10

C
11

D
9

Note: The multiplication operator has higher precedence than addition.
1. Report
Question: What does a |= b do?
A
Adds b to a

B
Performs bitwise OR and assigns the result to a

C
Sets a to b

D
None

Note: This is a compound assignment operator that combines bitwise OR with assignment.
1. Report
Question: What will 3 | 1 evaluate to?
A
1

B
2

C
3

D
4

Note: The bitwise OR results in 3 (binary 11 | 01 = 11).
1. Report
Question: What does the ^ operator do?
A
Bitwise OR

B
Bitwise XOR

C
Logical AND

D
None

Note: The ^ operator returns 1 for differing bits.
