The bitwise right shift (>>) operator shifts bits to the right. 1100 >> 1 is 0110. 1100 >> 2 is 0011. 1100 >> 3 is 0001. Note that in the third case we shifted a bit off the right end of the number, so it is lost.

WebAfter the seventh shift the 1 bit reached the highest bit, but since we have an 8 bit signed integer we interprete 10000000b not as 128 but as -128 and so var < INT_MAX will always be true.
