Answer 1: The problem is that a large herd contains 10,000 sheep. That’s

40,000 legs. The maximum number you can fit in a

short int is 32,767.

That’s smaller than 40,000, so (10,000*4) causes an overflow that results in

wrong data being output.

Answer 2: The problem is that the statement:

// The bit we are printing now

short int bit = (1<<16);

does not set the variable bit to 1000 0000 0000 0000(b). Instead, it sets it to

1 0000 0000 0000 0000(b). Unfortunately, it can’t hold 17 bits, so the

result ...
