What does a&b mean in c++

The a&b operation in C represents the bitwise AND operation of a and b, comparing the two numbers bit by bit. If the two corresponding bits are both 1, the result is 1, otherwise it is 0.

The meaning of a&b in c

Short answer:
the meaning of a&b in c a&b represents the bitwise AND operation of a and b.

Detailed explanation:

• Bitwise AND operation:

  • Bitwise AND The operation compares two numbers bit by bit. If both corresponding bits are 1, the result is 1, otherwise it is 0.

• ##a&b means: The

  a&b operation performs a bitwise AND operation on the binary representations of a and b.
  • For example, if a is 3 (011) and b is 5 (101), then a&b = 1 (001).

Uses:

Bitwise AND operations are typically used for the following purposes:

Checking bits Whether to set: a&1 checks whether the least significant bit of a is 1.
• Clear bit: a&~(1<Extract bits: a&(1<Oddify numbers: a&1 makes a an odd number.
