bitset::operator==
Tests a target bitset for equality with a specified bitset.
bool operator ==(
const bitset<N>& _Right
) const;
Parameters
- _Right
The bitset that is to be compared to the target bitset for equality.
Return Value
true if the bitsets are the same; false if they are different.
Remarks
Bitsets must be of the same size to be tested for equality by the member operator function.
Example
// bitset_op_EQ.cpp
// compile with: /EHsc
#include <bitset>
#include <iostream>
int main( )
{
using namespace std;
bitset<5> b1 ( 7 );
bitset<5> b2 ( 7 );
bitset<5> b3 ( 2 );
bitset<4> b4 ( 7 );
if ( b1 == b2 )
cout << "Bitset b1 is the same as bitset b2." << endl;
else
cout << "Bitset b1 is different from bitset b2." << endl;
if ( b1 == b3 )
cout << "Bitset b1 is the same as bitset b3." << endl;
else
cout << "Bitset b1 is different from bitset b3." << endl;
// This would cause an error because bitsets must have the
// same size to be tested
// if ( b1 == b4 )
// cout << "Bitset b1 is the same as bitset b4." << endl;
// else
// cout << "Bitset b1 is different from bitset b4." << endl;
}
Bitset b1 is the same as bitset b2. Bitset b1 is different from bitset b3.
