## Understanding the Problem

Let's begin our journey by gaining a clear understanding of the problem we'll tackle together. The task at hand involves extracting individual digits from a given number and then calculating their sum. For instance, consider the number 12345. In this scenario, we aim to compute the sum as follows: 1 + 2 + 3 + 4 + 5, which results in a sum of 15. This foundational concept not only helps in solving this particular problem but also lays the groundwork for mastering many other programming challenges and tasks. Understanding the problem's intricacies is key to effective problem-solving in the world of programming.

## Step-by-Step Guide

In our comprehensive step-by-step guide, we will methodically break down the process of creating a Raptor program to calculate the sum of digits in a number. Each step is designed to be clear and accessible, ensuring that learners of all levels can grasp the concepts effortlessly. By the end of this guide, you will not only have successfully created the program but will also have a deeper understanding of programming fundamentals. We'll start by obtaining user input, initializing essential variables, and then dive into the core logic of iterating through digits and adding them together. Our aim is to make the learning process both informative and enjoyable, helping you build a strong foundation in programming and problem-solving. Whether you're a novice taking your first steps into the world of coding or looking to reinforce your programming skills, our guide will equip you with the knowledge and confidence to tackle similar challenges in the future.

### Step 1: Input a Number

Begin the process by acquiring a number from the user, a crucial starting point in our program. We'll utilize the "Input" symbol in Raptor, marking it clearly as "Enter a number." This user input will be the foundation upon which we'll build our calculation of the sum of digits.

### Step 2: Initialize Sum

Next, we'll establish a mechanism to keep track of the accumulating sum of digits. In Raptor, this is achieved by initializing a variable using the "Declare Variable" symbol. We'll designate this variable as "sum_of_digits" and assign it an initial value of 0. This step lays the groundwork for efficient addition and ensures that our program can accurately calculate the sum as we progress through the digits of the entered number. The careful initialization of variables is a fundamental practice in programming, setting the stage for the successful execution of our digit-summing algorithm.

### Step 3: Iterate Through Digits

Here, we venture into the heart of our program's logic. To systematically process each digit in the number, we implement a loop structure. Loops, a cornerstone of programming, enable repetitive tasks and are represented in Raptor using symbols such as "While" or "For." The key is to design the loop to persist as long as there are additional digits to process. This meticulous setup ensures that no digit is left unaccounted for, paving the way for an accurate digit sum calculation.

### Step 4: Extract and Add Digits

As we delve into the heart of our program's logic, it's essential to extract and process each digit seamlessly. Within the loop we've established, we employ the "Get Next Digit" symbol. This invaluable tool enables us to extract each digit from the input number systematically. Each digit, as extracted, is temporarily stored, awaiting further processing. This meticulous step ensures that we account for every digit in the number, setting the stage for an accurate calculation of the sum of digits.

### Step 5: Add Digit to Sum

With each digit in our grasp, the next mission is to perform the actual addition. This is achieved by incorporating the extracted digit into our growing sum. We diligently add each digit to the "sum_of_digits" variable using the appropriate arithmetic operation symbol for addition. It's this step that builds our cumulative sum, bringing us ever closer to the final result. As we progress, this precise addition process ensures the accuracy of our digit sum calculation, leaving no room for error and demonstrating the power of systematic programming.

### Step 6: Repeat the Loop

As we continue our journey through the program, it's crucial to ensure the loop operates seamlessly. In this step, we perform a vital check to determine if there are additional digits left to process. By verifying this condition, we guarantee that the loop functions precisely as intended, leaving no digit unexamined. This attention to detail ensures the accuracy of our calculation, reinforcing the reliability of our digit summing algorithm.

### Step 7: Display the Result

The culmination of our efforts leads us to the moment when we can present the result of our digit sum calculation. Using the "Output" symbol, we reveal the sum of digits to the user. This step is pivotal, as it provides a clear and user-friendly display of the final result. It allows the user to see the outcome of our calculation, reinforcing the transparency and effectiveness of our program. By displaying the result, we bring our program full circle, completing the task and offering a tangible solution to the user.

## Testing the Program

Now that we've meticulously crafted our Raptor program, it's imperative to put it through its paces to ensure its reliability and functionality. Testing serves as the litmus test for any software, and our digit sum calculator is no exception.

When you run the program, you gain the opportunity to experiment with various inputs. Try entering different numbers, both large and small, to witness how our program calculates the sum of their digits. This hands-on experience is invaluable for gaining confidence in your programming skills and validating the correctness of our algorithm.

Testing also helps identify any potential edge cases or unexpected behaviors. By exploring a range of inputs, you can be confident that our program is robust and ready to handle a diverse array of scenarios. Whether you're using it for personal learning or practical problem-solving, rigorous testing ensures that our digit sum calculator is a reliable tool at your disposal. So, let's dive in and discover the capabilities of your newly created program.

```
# Raptor Program
sum_of_digits = 0
while number > 0:
digit = number % 10
sum_of_digits = sum_of_digits + digit
number = number // 10
output = "The sum of digits is: " + sum_of_digits
```
