C# Program to Find Whether a Given Number is Power of 2 using Bitwise Operators

This is a C# Program to find power of 2 using bitwise operator.

This C# Program Finds Power of 2 using Bitwise Operator.

Here Operations on bits at individual levels can be carried out using Bitwise operations and the whole representation of a number is considered while applying a bitwise operator.

Here is source code of the C# Program to Find Power of 2 using Bitwise Operator. The C# program is successfully compiled and executed with Microsoft Visual Studio. The program output is also shown below.

            Console.Write("Enter a number:");
            num = Convert.ToInt32(Console.ReadLine());
            bool result = ((num & -num) == num);
            Console.WriteLine(result);
            Console.ReadLine();
        }
    }
}

In this C# program, we are reading a number using ‘num’ variable. A bitwise operation is used to operations on bits at individual levels. The whole representation of a number is considered while applying a bitwise operator. Print the value of power of 2.

 
Enter a number:16
True
