Solve this multiple-choice question and choose the correct option.

The symbol & in programming languages like C and C++ is primarily used as the bitwise AND operator. Bitwise AND compares each bit of two numbers and returns a new number with bits set to 1 only if both bits were 1. For example: 5 & 3 results in 1 because: 5 = 1013 = 011& = 001 → 1 Note: In C/C++, the & symbol is also used as the "address-of" operator in certain contexts, but unless specified otherwise, the standard meaning is bitwise AND.

Correct Answer: Bitwise AND operator

Explanation

The symbol & in programming languages like C and C++ is primarily used as the bitwise AND operator.

Bitwise AND compares each bit of two numbers and returns a new number with bits set to 1 only if both bits were 1.
For example: 5 & 3 results in 1 because:

 5 = 1013 = 011& = 001 → 1

Note: In C/C++, the & symbol is also used as the "address-of" operator in certain contexts, but unless specified otherwise, the standard meaning is bitwise AND.
