Question
**Objective**: Write a C++ program to read and process temperature data.

### Instructions:

1. **File Reading**:
   - Read the date and average temperature from a file named `temps.txt`.
   - Use a `string` data type for the date and a `double` for the temperature average.

2. **Conversion**:
   - Convert the average temperature from Fahrenheit to Celsius.
   - **Conversion Formula**: 
     - Subtract 32 from the average (Fahrenheit).
     - Multiply the result by five and then divide by nine.
     - Formula: `(average - 32) * 5 / 9`.

3. **Output**:
   - Write the date, average temperature (Fahrenheit), and the converted Celsius temperature to a file named `celsi`.
   - Format the output using manipulators to ensure alignment with the sample shown in the chapter.
   - Ensure each number value is printed to one decimal place.

4. **Parameters Identification**:
   - **Input Parameters**: Data read from `temps.txt`.
   - **Output Parameters**: Data written to `celsi`.
   - **Constant Parameters**: Conversion factors for temperature (5/9).

### Activities:

- Design the program based on the requirements.
- Use data and formatting manipulators appropriately.
- Test the program with sample data to ensure accuracy in conversion and formatting.

This task will help reinforce skills in file handling, data processing, and output formatting in C++.
