Write a program digits sum.cpp that asks the user to enter a series of single-digit with nothing separating them (no negative number). Read the input as a C-string with a maximum length of 10. The program should display the sum of all the single-digit numbers in the string. For example, if the user enters 25 14, the program should display 12, which is the sum of 2, 5, 1, and 4. The program will continue asking the user input until the user enters a zero (i.e., 0) number. Note & Hint:

I have no idea how to complete this C++ assignment

### Program Explanation

The objective is to write a C++ program named `digits_sum.cpp` that prompts the user to enter a string of single-digit numbers (with no separators), and then calculates the sum of these digits. The program should continue to prompt for new inputs until the user enters zero (i.e., the digit '0').

#### Key Steps:
- Use a **C-string** to handle the input, with a maximum length of 10 characters.
- Ensure each character of the input is a valid digit.
- Use the `isdigit()` function from the `<cctype>` library for digit validation.
- Each valid character is converted to its numerical value by subtracting the character '0'.
- Continue processing until the input '0' is entered.

#### Notes & Hints:
- Allocate a sufficiently large character array to manage input.
- Validate all characters within the input string.
- Example code to convert a character to its integer form:

```cpp
char aDigit = '4';
int aNum;
aNum = aDigit - '0'; // now aNum = 4;
```

- Use the C-string library `<cstring>` to validate input length.

### Sample Output Explained

The output section illustrates various interactions with the `digits_sum.cpp` program:

1. **Input of "2514":**
- Prompt: “Please enter a number (max. length of 10) to sum: 2514”
- Result: “The sum of the digits 2514 is 12”

2. **Input of "1234567890":**
- Prompt: “Please enter a number (max. length of 10) to sum: 1234567890”
- Result: “The sum of the digits 1234567890 is 45”

3. **Input exceeding allowed length:**
- Prompt: “Please enter a number (max. length of 10) to sum: 123456789012”
- Result: “The number exceeds the length of 10”

4. **Invalid input containing non-digit characters:**
- Prompt: “Please enter a number (max. length of 10) to sum: 123ABC”
- Result: “Invalid input: non-digit character detected!”

5. **Termination condition:**
- Prompt: “Please enter a number (max. length of 10) to sum: 0”
