do you need assembly equivalent?

Answer 3

These are all basically bitwise assignment operators

1. A &= B is equal to A = A & B (AND)
2. A |= B is equal to A = A | B (OR)
3. A ^= C is equal to A = A ^ B (XOR)
4. A <<= B means A = A << B (Binary Left Shift)
5. A =>> B means A = A >> B (Binary Right Shift)

Examples :
Left hand side = A
Right hand side = B

1. 255 &= 128= 128
2. 255 |= 10 = 255
3. 255 ^= 100 = 150
4. 1 <<= 1 = 2 (0b00000010)
5. 128 >>= 1 = 64 (0b01000000)

Yaroslav Vernigora your links are really helpful before I knew some but not all of them but now ,it all clears.

Answer 5

On!oN have you tried to search for such links yourself? I found them in a search engine in five seconds. or are search engines not running in your country?

Answer 6

@Prashanth Kumar if it will clearly explain how the above operators work.
