test results in true, then the variable adjust is assigned the value 1; otherwise, it is as-

signed the value . In this example, the variable

c2 is 191, which is not less than 159,

so the variable

adjust is assigned the value .

e variable 4.

rowOffset is initialized by testing a condition. is condition is whether

the value of the variable

c1 is less than 16. If its value is less than 16, rowOffset is

initialized to 112. Otherwise, it is initialized to 176. Because

c1 is less than 16 in the

example,

rowOffset is initialized to 112.

e variable 5.

cellOffset is initialized by testing one or more conditions. e rst

condition is whether the variable

adjust is equal to 1. If this rst condition is not

met, the variable

cellOffset is initialized to 126. If this rst condition is met, another

condition is tested. If the variable

c2 is greater than 127, cellOffset will be initialized

to 32, and to 31 otherwise. Because

c1 is not equal to 1 in the example, cellOffset is

initialized to 126.

e object to which 6.

*p1 points is assigned the value of subtracting rowOffset from c1

(138 − 112 = 26), performing a le-shi, which is equivalent to multiplying a number

by two (26 × 2 = 52), then nally subtracting

adjust (52 −  = 52).

e object to which 7.

*p2 points is assigned the value of subtracting cellOffset from

itself (191 − 126 = 65).
