Questions: 30 questions and 2 programs time 1 hour. All Questions are multiple type. I just mention the questions options not remember

Section A:

1. Find the value of n the following code: int F(int n) if( n!=0& !(n&(n-1))) printf("%d",n) n is i. Even no ii. Odd nos iii. Non zero numbers iv. Number with power 2

Ans: iv.

Description: Take a number like 8. so n= 8 and n-1= 7 So n =1000 and n-1= 111 And n&n-1= 1000 & 111=1111( All bits one) Now !(n & n-1) = 0000 So if(0) which satisfies the if condition. Means when and is a number of power 2, it will satisfy if condition.

More Doubt Comments me.

Section A:1. Find the value of n the following code:

int F(int n)

if( n!=0& !(n&(n-1)))

printf("%d",n)

n is

i. Even no

ii. Odd nos

iii. Non zero numbers

iv. Number with power 2

Ans: iv.

so n= 8 and n-1= 7

So n =1000 and

n-1= 111

And n&n-1= 1000 & 111=1111( All bits one)

Now !(n & n-1) = 0000

So if(0) which satisfies the if condition. Means when and is a number of power 2, it will satisfy if condition.
