Quadruple
It contains 4 fields:
- Operator
- Argument 1

It requires more no of temporary variables so that it requires more space in the symbol table To avoid this we use a triple add code representation.
| Operator | Arg 1 | Arg 2 | Request | |
| 0 | + | x | y | t1 |
| 1 | / | a | b | t2 |
| 2 | * | t1 | t2 | S |
