Need help with the following question in relations to MARIE and assembly
![### Assembly Program Description
The following is an example of a MARIE assembly language program and the steps to assemble it:
#### Program Instructions
| Memory Address (Hexadecimal) | Instruction |
|------------------------------|---------------|
| 110 | Load A |
| 111 | Sub B |
| 112 | Store C |
| 113 | Halt |
| A | 0016 |
| B | FEDE |
| C | 0000 |
### Tasks
1. **Show the symbol table after the first pass.**
2. **Show the translated instructions after the first pass.**
3. **Show the translated instructions after the second pass.**
---
### 1. Symbol Table After the First Pass
The symbol table is created during the first pass of the assembler. It records the addresses assigned to the labels used in the program.
| Symbol | Address |
|--------|---------|
| A | 114 |
| B | 115 |
| C | 116 |
### 2. Translated Instructions After the First Pass
During the first pass, the assembler translates symbolic addresses to numerical addresses but does not yet resolve the data part. Here’s what it looks like:
| Memory Address (Hexadecimal) | Machine Code |
|------------------------------|-----------------------------|
| 110 | Load [114] |
| 111 | Sub [115] |
| 112 | Store [116] |
| 113 | Halt |
| 114 | 0016 |
| 115 | FEDE |
| 116 | 0000 |
### 3. Translated Instructions After the Second Pass
In the second pass, the assembler resolves the symbolic addresses to their corresponding numeric values and produces the final machine code.
| Memory Address (Hexadecimal) | Machine Code |
|------------------------------|--------------|
| 110 | 3014 |
| 111 | 3115 |
| 112 | 3216 |
| 113 | 7000 |
| 114 | 0016 |
| 115 | FEDE |
| 116 | 0000 |
**Explanation:**
- **110:** Load A translates to `3014` (Load operation with address 114).
- **111:** Sub](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe4b2d173-202d-41b4-bba9-cde13f36ca19%2F71c06223-f07b-4c01-ba9c-e5368b86c31b%2Fh59vw5a_processed.png&w=3840&q=75)

| 114 | 0016 |
| 115 | FEDE |
| 116 | 0000 |
**Explanation:**
- **110:** Load A translates to `3014` (Load operation with address 114).
- **111:** Sub
