What is the default value of a bitset?
a Explanation: By default, all the bits of a bitset variable is set to 0 i.e. the value of bitset variable is 0.

Which operator is used to access the nth bit in a bitset?
b Explanation: [] operator is used to access the nth bit of a bitset from the right side. For example, if my bitset b is 1010 then b[0] represents 0 and b[1] represents 1.

Which of the following is the limitation of bitset over vector bool?
b Explanation: Bitset size is static whereas vector size is dynamic therefore the size of a vector can be increased or decreased which is not possible in bitset.
b
See lessExplanation: Bitset size is static whereas vector size is dynamic therefore the size of a vector can be increased or decreased which is not possible in bitset.
Which of the following is correct about bitset and vector of bools?
d Explanation: Bitset consumes less space compared to bool vector however the size for bitset is static whereas for bool vector size is dynamic.
d
See lessExplanation: Bitset consumes less space compared to bool vector however the size for bitset is static whereas for bool vector size is dynamic.
What is bitset in C++?
a Explanation: Bitset is a collection of bool variables with each element consuming only one bit. They are introduced for efficient use of memories.
