std::bitset::operator==, std::bitset::operator!= - cppreference.com (original) (raw)

bool operator==( const bitset& rhs ) const; (1) (noexcept since C++11) (constexpr since C++23)
bool operator!=( const bitset& rhs ) const; (2) (noexcept since C++11) (until C++20)

  1. Returns true if all of the bits in *this and rhs are equal.

  2. Returns true if any of the bits in *this and rhs are not equal.

The != operator is synthesized from operator==. (since C++20)

[edit] Parameters

[edit] Return value

  1. true if the value of each bit in *this equals the value of the corresponding bit in rhs, otherwise false.

  2. true if !(*this == rhs), otherwise false.

[edit] Example

Compare given bitsets to determine if they are identical:

Output:

b1 == b2: true b1 == b3: false b1 != b3: true
