*Problem 1*
%d is used to take a signed integer as input. To take a short integer as
input, use %hi. That way, you would get the correct answer as 2.
*Problem 2:*
a:1 means that variable a is of width *1 bit*
Similarly, b:2 means that b is of width *2 bits*
b = 6 sets the two bits as 10, (last two bits of 110 considered), which is
equal to -2
a = 2 sets the only bit as 0, (last bit of 10 considered), which is nothing
but zero.
Bit-fields like these however tend to be implementation-dependent and in the
interest of portability should be avoided.
