Question

Anyone can explain.what these two statements are doing
int z=x&y;
int w=z|(y^255);

Answer 1

& is 'bitwise and' operator. It compares two numbers bit by bit and performs AND Operation.

3&4 is 0011&0100... each bit is compared with other bit.

| is 'bitwise or' operator. It works same as & but it performs OR operation.

[edit]

^ is "bitwise XOR" opetator. it performs XOR operation.
