CISP 360 Ch 3
Evaluate each expression, assuming w = 1, x = 3,y = 4, and z = -2 then select the correct answer from the list. Assume that each expression is evaluated independently (i.e. if a variable is modified in one expression, it does not effect another expression). 4 % x * w - + z / 2 A B C D E
