C++ <bitset> - operator!= Function

The C++ bitset::operator!= function is used to check if two bitsets are equal or not. It returns true if two bitsets are not equal, else returns false.

Syntax

C++98
C++11

bool operator!= (const bitset& rhs) const;

bool operator!= (const bitset& rhs) const noexcept;

Parameters

rhs Specify right-hand side bitset object.

Return Value

Returns true if two bitsets are not equal, else returns false.

Exception

Never throws exceptions.

Example:

In the example below, the bitset::operator!= function is used to check if two bitsets are equal or not.

#include <iostream>
#include <bitset>
using namespace std;
 
int main (){
  bitset<4> bset1("1001");
  bitset<4> bset2("1001");
  bitset<4> bset3("1111");

  cout<<boolalpha;
  //checking if bitsets are equal or not
  cout<<"(bset1 != bset2): "<<(bset1 != bset2);
  cout<<endl;
  cout<<"(bset1 != bset3): "<<(bset1 != bset3);

  return 0;
}

The output of the above code will be:

(bset1 != bset2): false
(bset1 != bset3): true
