int i = 2, j = i; if (Convert.ToBoolean((i | j & 5) & (j - 25 * 1))) Console.WriteLine(1); else Console.WriteLine(0);

Question

what is the output please explain

Answer 1

int i = 2; // 0000 0010
int j = i; // 0000 0010

if (Convert.ToBoolean((i | j & 5) & (j - 25 * 1)))
Console.WriteLine(1);
else
Console.WriteLine(0);

for (i | ( j & 5)) we have

0000 0010 = 2
& 0000 0101 = 5
------------------
0000 0000 = 0
| 0000 0010 = 2
---------------------
0000 0010 = 2

(j - 25 * 1) = -23 = 1110 1001 (23 = 0001 0111)

0000 0010 = 2
& 1110 1001 = -23
---------------------
0000 0000 = 0

Here, our evaluation yields 0 and if (false)

then program flow picks else and output will be 0;
