Question
### 24. Using Files—Numeric Processing

If you have downloaded this book's source code from the Computer Science Portal, you will find a file named `Random.txt` in the Chapter 05 folder. (The Portal can be found at [www.pearsonhighered.com/gaddis](http://www.pearsonhighered.com/gaddis).) This file contains a long list of random numbers. Copy the file to your system, then write a program that:

1. Opens the file.
2. Reads all the numbers from the file.
3. Calculates the following:
   - **A)** The number of numbers in the file.
   - **B)** The sum of all the numbers in the file (a running total).
   - **C)** The average of all the numbers in the file.

The program should display the number of numbers found in the file, the sum of the numbers, and the average of the numbers.

### Note:
The task involves coding skills and basic file I/O operations, which are essential in many programming languages. Make sure to handle possible errors like file not found or improper file format gracefully in your program. This exercise helps to reinforce concepts of file handling and basic numerical processing, such as summation and computation of averages.
