What are the various methods of implementing three address statements?

The three address statements can be implemented using the following methods.
 Quadruple: a structure with at most four fields such as operator (OP), arg1, arg2, result.
 Triples: the use of temporary variables is avoided by referring the pointers in the
symbol table.
 Indirect triples: the listing of triples has been done and listing pointers are used instead of
using statements.
