Cycle 4 — p15: Three-Address Code Generator

Files:

• p15.c - Implementation of three-address code generation

Brief description:

This program generates three-address code (TAC) from arithmetic expressions. Features:

1. Expression Processing:

   • Handles arithmetic expressions with multiple operators
   • Supports operators: /, *, +, -, =
   • Maintains proper operator precedence

2. Code Generation:

   • Produces three-address code format:
     • Operator Destination Operand1 Operand2
   • Uses temporary registers (Z, Y, X, etc.)
   • Generates code in the correct evaluation order
   • Handles binary operators properly

3. Output Format:

Oprtr   Destn   Op1    Op2

Example:

Input: a+b*c
Output:
*       Z       b       c
+       Y       a       Z

Usage: Enter an arithmetic expression, and the program will generate the corresponding three-address code following operator precedence.
