**Assignment Overview: Implementing a Stack Data Structure in C++**

This educational assignment involves creating a stack data structure using C++. You can accomplish this by utilizing the C++ Standard Template Library (STL) or by crafting a user-defined class.

**Task Breakdown:**

1. **Stack Implementation:**
   - Create a stack data structure using C++.
   - Develop an interactive program. 
   - Transactions are entered as a batch via a text file at the command line using redirection.
   - The results of each transaction will appear on the console.
   - **Example Command:** `$ prog3 < prog3.dat`

2. **Transaction Details:**
   - Each transaction comprises an arithmetic expression in postfix notation. 
   - Expect operations like `+, -, *, /, %, ^` with operands without spaces.
   - Do not assume error-free input:
     - Handle division by zero (`/` or `%`) by displaying an error and moving to the next transaction.
     - Manage `%` with non-integers by showing an error and proceeding.
   - Intermediate and final results can be negative or non-integer.

   **Sample Transactions and Results:**
   - a. `23+`  (result = 5)
   - b. `34*5/`  (result = 2.4)
   - c. `832*6/`  (result = "error: division by zero")
   - d. `48*62*42^3-%` (result = 4)
   - e. `92/73/5%4/+` (result = "error: non-integer operand for %")

3. **End-of-File Indication:**
   - An "end-of-file" transaction marks the end of processing.
   - Implement a stack to evaluate and display results using either STL or a custom class.

4. **Program Execution:**
   - Run the program via command prompt in the directory with the compiled executable.
   - The program prompts for input, such as “Please enter an expression in postfix notation:”.

This task aims to enhance understanding of stack data structures and their applications in arithmetic expression evaluation using C++.
