Code:
#include
void main()
{
int num, x, y, count = 0;
printf("enter the number:");
scanf("%d", &num);
x = num << 1;
y = x ^ num;
y = y + 1;
/* Checks if the number is in powers of 2 */
while ((y / 2) != 0)
{
if (y % 2 != 0)
{
count++;
break;
}
else
{
y = y / 2;
}
}
if (count)
{
printf("false");
}
else
{
printf("true");
}
}
Output:
enter the number:85
true
$ a.out
