Answer 1

Yes.

&& , || are logical operators, works as compound conditional expressions..

&, | are bitwise logical operators works at bit level manipulations.

Answer 2

Jayakrishna🇮🇳 ooh I got confused by &&
So if
a = 0
b = 1
Printf(" %d, %d", a||b , a&&b );
O/p = 1, 0

a = 4
b = 6
Printf(" %d, %d", a|b , a&b );
O/p = 6, 4
Is this correct ?

Answer 3

Anything , other than 0 value will be true in boolean equivalence. 0 means false.
So 2&&4 is true && true => true
true => 1 as integer value is the answer.

Answer 4

Jayakrishna🇮🇳 ok but what if I want to print answer by this logic -
In binary 2 = 10 and 4= 100 and their AND operation will result zero
How can I achieve this?

Answer 5

Use bitwise and operator & => a&b
printf("%d",a&b)

a&b => 0010 & 0100 = 0000
a&&b => 2&&4 => true && true = true
