Aim To perform bitwise set and reset

Theory

Experiment 4(a)

Bitwise operations work directly on the binary representations of integers, allowing efficient data manipulation. Key operations include:

1. Bitwise AND (&): Sets bits to 1 where both operands have 1.
2. Bitwise OR (|): Sets bits to 1 if at least one operand has 1.
3. Bitwise XOR (^): Sets bits to 1 where operands differ.
4. Bitwise NOT (~): Inverts all bits.
5. Left Shift (<<): Shifts bits to the left, effectively multiplying by 2.
6. Right Shift (>>) : Shifts bits to the right, effectively dividing by 2.

Experiment 4(b)

• Setting a Bit: Alters a bit to 1 at a specific position.
• Resetting a Bit: Alters a bit to 0 at a specific position.

Algorithm

For Experiment 4(a)

1. Start
2. Declare variables a and b.
3. Input values for a and b.
4. Perform Bitwise Operations:
   • AND: a & b
   • OR: a | b
   • NOT: ~a
   • XOR: a ^ b
   • Left Shift: a << 1
   • Right Shift: a >> 2
5. Output results for each operation.
6. End

For Experiment 4(b)

1. Start
2. Declare variables a, i, set, and reset.
3. Input a and shift position i.
4. Compute:
   • Set Bit: set = a | (1 << i)
   • Reset Bit: reset = a & (~(1 << i))
5. Output set and reset results.
6. End
