Three-address code is an intermediate code used in compilers. It is a sequence of statements of the general form:

X = Y op Z

Where X, Y, and Z are simple variables, and op is an operator. The representations of three address code are:

1. Quadruples: Quadruples are a common form of representing three address code. They consist of four fields: operator, argument1, argument2, and result. For example, for the statement "a = b + c", the quadruple would be (+, b, c, a).

2. Triples: Triples are another form of representation. They consist of three fields: operator, argument1, and argument2. The position of the triple implicitly represents the result. For example, for the statement "a = b + c", the triple would be (+, b, c) and the position of this triple in the list of triples represents 'a'.

3. Indirect Triples: Indirect triples are a modification of triples. They consist of a list of pointers to triples rather than the triples themselves. This allows for easy rearrangement of the statements for optimization.

Each of these representations has its own advantages and disadvantages, and the choice of which to use depends on the specific requirements of the compiler.
