The left-shift operator (<<) shifts the bits of its left operand to the left by the number of bits specified in its right operand. Bits vacated to the right are replaced with
0s; bits shifted off the left are lost. In Fig. 20.11, line 11 assigns variable
number1 the value
00000000 00000000 00000011 11000000). The result of left-shifting variable
number1 eight bits in the expression
number1 << 8 (line 17) is
00000000 00000011 11000000 00000000).
