Check whether given number is power of 2 are efficiently

Here given code implementation process.

// C Program for
// Check whether given number is power of 2 are efficiently
#include <stdio.h>

// Detect that given number are part of power of 2 or not
void isPowerTwo(int number)
{
	if (number <= 0 || (number & (number - 1)) != 0)
	{
		printf("%d Is not a power of two\n", number);
	}
	else
