Solution

1. Break Down the Problem

We have a function func(int a, int b) that performs a left bitwise shift on a by b positions. We need to determine the output when func(8, 2) is called.

2. Relevant Concepts

The left shift operator << shifts the bits of a number to the left. Shifting left by b positions is equivalent to multiplying the number by 2b2^b.

3. Analysis and Detail

Given:

  • a=8 a = 8
  • b=2 b = 2

Calculating the result: c=a<<b=8<<2 c = a << b = 8 << 2 This operation effectively means: 8×22=8×4=32 8 \times 2^2 = 8 \times 4 = 32

4. Verify and Summarize

The left shift of 8 by 2 results in 32. The computation matches the expected operation of the left shift.

Final Answer

The output for func(8, 2) is d. 32.
