(a) Used to make alternate bits zero

(b) Used to make a bit 0 in a bitset

(c) Used to make all bits 1

(d) Used to make a bit(s) 0 in a bitset

This question was addressed to me in an online interview.

My query is from Bitset in section Class Hierarchies, Library & Containers of C++

Answer 1

The correct choice is (d) Used to make a bit(s) 0 in a bitset

Easiest explanation - <bitset> header provides the reset() function to set bit(s) to 0 in a bitset variable.
