Check if a Number is Odd or Even using Bitwise Operators

// C++ program to check for even or odd 
// using Bitwise AND operator 
  
#include <iostream>  
using namespace std;  
    
// Returns true if n is even, else odd  
bool isEven(int n)  
{  
    // n&1 is 1, then odd, else even  
    return (!(n & 1));  
}  
    
// Driver code  
int main()  
{  
    int n = 101;  
    isEven(n)  
? cout << "Even" 
: cout << "Odd";  
    return 0;  
}  
// C++ program to check for even or odd 
// using Bitwise XOR operator 
  
#include <iostream>

{ 
  
    // n^1 is n+1, then even, else odd

        return true;
