The for loop
for (i=0; i<10; ++i)
printf("%d", i&1);
prints:
(A) 0101010101
(B) 0111111111
(C) 0000000000

for (i=0; i<10; ++i)
printf("%d", i&1);
i=0: 0000 AND 0001 = 0000
i=1: 0001 AND 0001 = 0001
i=2: 0010 AND 0001 = 0000
i=3: 0011 AND 0001 = 0001
.
.
and so on till i=9.
Output printed will be = 0101010101
Option (A) is correct.
