Here, gen is a function that generates the output code, and newtemp is a function that returns the name of a new temporary variable on every call. Assume that ti's are the temporary variable names generated by newtemp. For the statement 'X : = Y + Z', the 3-address code sequence generated by this definition is

$$X = Y + Z$$

$${t_1} = Y + Z;X = {t_1}$$

$${t_1} = Y;{t_2} = {t_1} + Z;X = {t_2}$$
