Three address code
In computer science, three address code is a form of representing intermediate code at compiling process.
Each statement has the general form of
<math>x := y\ op\ z<math>
where x, y and z are variables, constants or temporary variables generated by the compiler. op represents any operator, e.g. an arithmetic operator.
Compound statements such as
<math>p := x + y * z<math>
are not allowed. They have to be translated in three address code, such as
<math>t1 := y * z<math>
<math>p := t1 + x<math>
