We've included the necessary header files and function declarations that play a vital role in crafting your rocket program. These declarations ensure that your program operates seamlessly and efficiently. From here, you'll embark on a coding adventure that involves setting up the foundations for your rocket's ascent.

Main Function

```cpp int main() { int width; int height; int numStages; getDimensions(width, height, numStages); drawRocket(width, height, numStages); } ```

As you delve deeper into the code, you'll encounter the central command center of your rocket program: the main function. It's here where the magic begins, serving as the launchpad for your coding expedition. The main function is responsible for initializing the key variables that dictate your rocket's characteristics, such as width, stage height, and the number of stages. This function acts as the control tower, orchestrating the entire rocket-building process.

getDimensions Function

```cpp void getDimensions(int &width, int &height, int &numStages) { // Prompt user for input cout << "enter width: "; cin >> width; cout << "enter height of each stage: "; cin >> height; cout << "enter number of stages: "; cin >> numStages; } ```

Now, let's turn our attention to the getDimensions function, a critical component in your rocket program. It's the communication hub that connects your coding world with the real-world input. With this function, you gain the power to retrieve user input for your rocket's width, the height of each stage, and the total number of stages. The getDimensions function ensures that your rocket becomes a dynamic creation, allowing you to tailor its specifications to your imagination. It's the window through which you can interact with your rocket, transforming your vision into code.

drawRocket Function

```cpp void drawRocket(int width, int height, int numStages) { int countBoxes; drawCone(width); for (countBoxes = 0; countBoxes < numStages; countBoxes++) { drawBox(width, height); } drawCone(width); } ```

The drawRocket function is the heart of your rocket-building endeavor. It's the powerhouse that assembles your complete rocket shape, step by step. It commences by crafting a majestic cone at the rocket's pinnacle using the drawCone function, setting the stage for an awe-inspiring liftoff. As your journey continues, a loop springs into action, fabricating the rectangular stages of your rocket with meticulous precision, layer by layer. And finally, as your rocket nears completion, the drawRocket function concludes the symphony by bestowing your creation with another splendid cone at the bottom, ready to soar into the coding cosmos.

drawCone Function

```cpp void drawCone(int width) { if (width % 2 != 0) { drawOddCone(width); } else { drawEvenCone(width); } } ```

The drawCone function is your coding compass, discerning whether to fashion an eccentric or even cone for your rocket, guided by the width you've chosen. It ensures that your rocket's crown, the top cone, aligns with your vision, whether it's an odd or even spectacle. This adaptability adds a dynamic touch to your rocket design, allowing you to explore various shapes and configurations, all meticulously drawn with the finesse of C++.

drawOddCone and drawEvenCone Functions

```cpp void drawOddCone(int width); void drawEvenCone(int width); ```

Meet the dynamic duo, the drawOddCone and drawEvenCone functions, responsible for sculpting the top cone of your rocket. When the width of your rocket is an odd number, drawOddCone takes the stage, orchestrating a mesmerizing display. Conversely, when the width is even, drawEvenCone emerges, weaving an equally enchanting spectacle. Both functions utilize loops to construct the intricate cone shape, ensuring that your rocket's appearance aligns perfectly with your creative aspirations. With their expertise, your rocket's crown will be a work of coding artistry, captivating the imagination of all who behold it.

printSpacesBeforeX Function

```cpp #include using namespace std; void printSpacesBeforeX(int i) { for (int n = 1; n < i; ++n) { cout << " "; // Print spaces before printing 'X' } } ```

In the intricate world of rocket design, every detail counts, including the spaces before 'X' characters in each row of the cone. The printSpacesBeforeX function is your precision tool, meticulously crafting the spacing to ensure that your rocket's appearance is flawless. It's the brushstroke that maintains the symmetry and elegance of your rocket's cone, setting the stage for a captivating visual experience.

drawTipCone Function

```cpp #include using namespace std; void drawTipCone(int width, int i) { if ((width - i * 2) > 0) { // Draw a row of 'X's for the tip of the cone for (int j = 0; j < width - (i * 2); j++) { cout << "X"; } } else { cout << "X" << endl; } } ```

For the pinnacle of your rocket, the tip cone, the drawTipCone function takes the center stage. It's tasked with adorning this crucial section with a row of 'X's, each placed with calculated precision. Drawing a seamless and elegant row, it adjusts the width with finesse, ensuring that your rocket's tip captures the essence of perfection. As you embark on your rocket-building journey, the drawTipCone function will be your artistic touch, making the tip of your rocket a true masterpiece.

drawBox Function

<code ignore--minify class="code-view">```cpp #include using namespace std; void drawBox(int width, int height) { // Draw the top horizontal line for (int i = 0; i &lt; width; i++) { cout &lt;&lt; "X"; } cout &lt;&lt; endl; // Draw the vertical sides with spaces in between for (int j = 0; j &lt; height - 2; j++) { cout &lt;&lt; "X"; for (int k = 0; k &lt; width - 2; k++) { cout &lt;&lt; " "; } cout &lt;&lt; "X" &lt;&lt; endl; } // Draw the bottom horizontal line for (int i = 0; i &lt; width; i++) { cout &lt;&lt; "X"; } cout &lt;&lt; endl; } ``` </code>

While the cones of your rocket capture the eyes, the drawBox function is the craftsman of the rectangular stages that form the rocket's body. Each stage is a combination of horizontal lines and vertical sides composed of 'X' characters. The drawBox function meticulously builds each stage, ensuring that the rocket's body is sturdy and visually appealing. It's the structural foundation that ensures your rocket can withstand any coding challenge, making it not just beautiful but also functional.

drawHorizontalLine Function

```cpp #include using namespace std; void drawHorizontalLine(int numXs) { // Draw a horizontal line of 'X's for (int i = 0; i < numXs; i++) { cout << "X"; } cout << endl; } ```

In the intricate world of rocket design, precision is paramount, even when it comes to drawing horizontal lines. The drawHorizontalLine function carries this responsibility with grace, meticulously creating a horizontal line comprised of 'X' characters. It ensures that the number of 'X' characters is just right, contributing to the impeccable appearance of your rocket's stages. This function is your assurance of a rocket that not only soars high but looks captivating while doing so.

draw2VerticalLines Function

```cpp #include using namespace std; void draw2VerticalLines(int numSpaces, int numRows) { for (int rowCount = 0; rowCount < numRows; rowCount++) { // Create a row with vertical sides and spaces in between cout << "X"; for (int spaceCount = 0; spaceCount < numSpaces; spaceCount++) { cout << " "; } cout << "X" << endl; } } ```

To add depth and structure to your rocket's stages, the draw2VerticalLines function steps in as the architect. It meticulously creates vertical lines on the sides of a box, enhancing the box's three-dimensional appearance. It achieves this by calling the drawOneRow function multiple times, mirroring the number of rows required. The result is a beautifully crafted rocket stage that not only serves its purpose but also adds an aesthetic dimension to your coding journey.

drawOneRow Function

```cpp #include using namespace std; void drawOneRow(int numSpaces) { // Draw the left side of the row cout << "X"; // Draw spaces between the left and right sides for (int spaceCount = 0; spaceCount < numSpaces; spaceCount++) { cout << " "; } // Draw the right side of the row and move to the next line cout << "X" << endl; } ```

The drawOneRow function is the artisan behind the scenes, meticulously crafting each row of your rocket's stage. It combines 'X' characters and strategically placed spaces, ensuring that the stage's appearance is both robust and visually pleasing. The balance it strikes between 'X' characters and spaces contributes to the overall elegance of your rocket's design. It's the fine brushstroke that gives your rocket's stages a touch of artistry, making them not just functional but aesthetically appealing. With the drawOneRow function, your rocket's stages become more than just code – they become a work of coding art.
