+// Track 1: Core Infrastructure & Basic Expressions
+// * Create intermediate_code.h/.c defining the instruction structure:
+//   - Struct with fields for: opcode, result, operand1, operand2, label
+//   - Enum for all operation types (ADD, SUB, MUL, DIV, etc.)
+// * Implement temp variable generator function that produces unique names (t1, t2, etc.)
+// * Create specific code emission functions:
+//   - emit_binary_op(char* result, char* op, char* arg1, char* arg2)
+//   - emit_unary_op(char* result, char* op, char* arg)
+//   - emit_assignment(char* target, char* source)
+// * Add Bison actions for arithmetic expressions:
+//   - Addition: $$ = new_temp(); emit_binary_op($$, "ADD", $1, $3);
+//   - Subtraction, multiplication, division, modulo
