Algorithm

Bitwise Operators:

  1. AND Operator (&):

    • Performs a bitwise AND operation.
    • Example: result = a & b;

  2. OR Operator (|):

    • Performs a bitwise OR operation.
    • Example: result = a | b;

  3. XOR Operator (^):

    • Performs a bitwise exclusive OR operation.
    • Example: result = a ^ b;

  4. NOT Operator (~):

    • Performs a bitwise NOT operation, inverting each bit.
    • Example: result = ~a;

Bit Shift Operators:

  1. Left Shift Operator (<<):

    • Shifts the bits of the left operand to the left by a specified number of positions.
    • Example: result = a << 2; (Left shift a by 2 positions.)

  2. Right Shift Operator (>>):

    • Shifts the bits of the left operand to the right by a specified number of positions.
    • For unsigned types, it fills the vacant positions with zeros.
    • For signed types, it fills the vacant positions with the sign bit (0 for positive, 1 for negative).
    • Example: result = a >> 3; (Right shift a by 3 positions.)

Common Bitwise Techniques:

  1. Setting a Bit:

    • Use the OR operator to set a specific bit to 1.
    • Example: a = a | (1 << position);

  2. Clearing a Bit:

    • Use the AND operator with the bitwise NOT operator to clear a specific bit to 0.
    • Example: a = a & ~(1 << position);

  3. Toggling a Bit:

    • Use the XOR operator to toggle a specific bit.
    • Example: a = a ^ (1 << position);

  4. Checking if a Bit is Set:

    • Use the AND operator to check if a specific bit is set.
    • Example: if ((a & (1 << position)) != 0) { /* Bit is set */ }

  5. Checking if a Bit is Clear:

    • Use the AND operator to check if a specific bit is clear.
    • Example: if ((a & (1 << position)) == 0) { /* Bit is clear */ }
