TAC Handout written by Maggie Johnson and revised by me. Three address code Three-address code(TAC) will be the intermediate representation used in our Decaf compiler. It is essentially a generic assembly language that falls in the lower-end of the mid-level IRs. Some variant of 2, 3 or 4 address code is fairly commonly used as an IR, since it maps well to most

Describe how a two-dimensional array is implemented as an array of arrays. Manipulate a collection of objects using a vector. Use MultiInputBox object from the javabook package to input an array of strings

If the salinity(含盐量)of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation-conversion of liquid water to water vapour. In this manner,the salinity is increased, since the salts stay behind. If this is carried to the extreme,of course, white crystals of salt would be left behind; this, by the way,is how much of the table salt we use is actually obtained
