Design a Simple 3-Address Code IR

Your Task

Design and implement a simple three-address code intermediate representation.

Requirements

1. Define data structures:

   • Instruction type (enum or struct)
   • Instruction structure with fields: operator, operands, result
   • Instruction list/array to store the program

2. Supported operations:

   • Arithmetic: +, -, *, / (binary)
   • Assignment: = (copy)
   • Labels for control flow
   • Comments

3. Implementation functions:

   • Create new instruction
   • Add instruction to list
   • Print instruction in readable format
   • Clear/free instruction list

4. Output format: t1 = b * c t2 = a + t1 x = t2

Success Criteria

• Instructions can be created and stored
• Instructions print in "result = arg1 op arg2" format
• Support for at least 4 arithmetic operators
• Proper handling of constants, variables, and temporaries
