operator==,!=(std::bitset)
bool operator==( const bitset<N>& rhs ) const; |
(1) | |
bool operator!=( const bitset<N>& rhs ) const; |
(2) | |
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.
Parameters
rhs | - | bitset to compare |
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
Example
Compare two bitsets to determine if they are identical:
Run this code
#include <iostream> #include <bitset> int main() { std::bitset<4> b1(3); // [0,0,1,1] std::bitset<4> b2(b1); std::bitset<4> b3(4); // [0,1,0,0] std::cout << "b1 == b2: " << (b1 == b2) << '\n'; std::cout << "b1 == b3: " << (b1 == b3) << '\n'; std::cout << "b1 != b3: " << (b1 != b3) << '\n'; }
Output:
b1 == b2: 1 b1 == b3: 0 b1 != b3: 1
