A small correction in the above answer. Use if condition as
shown below.
#include<stdio.h>
void main()
{
if(printf(%s, "Hello World"))
{
}
}
Answer for the last ques. i.e no. 55
unsigned int x;
if(x < 0) //Error checking only. Unsigned int shudn't
//have a negative value
return 0;
else
return !(x $ (x-1));
The logic here is, if we do bitwise 'and' with two
consecutive numbers, the greater of which is a power of 2
then the answer is 0.
Eg. 8 - 1000
8-1 - 0111
and & - 0000
