+### **Solution: Markdown to PDF Conversion**
+
+To convert Markdown to PDF, we can utilize both online tools and local software. Here’s how to set up and use these tools effectively.
+
+#### **Online Tools**
+
+1. **md2pdf**:
+   - A straightforward online tool for converting Markdown to PDF, accessible [here](https://md2pdf.netlify.app/).
+   - **Advantages**: Quick and easy to use; highlights important keywords in commands like `SELECT` and `JOIN`.
+   - **Disadvantages**: Does not handle wide tables well (horizontally large tables are cut off).
+2. **Markdown to PDF**:
+   - Another user-friendly online converter, accessible [here](https://www.markdowntopdf.com/). Note that after one conversion, login is required, and three conversions are allowed before requiring a premium account.
+   - **Advantages**: Handles horizontally large tables well; layout is similar to GitHub’s Markdown preview.
+   - **Disadvantages**: No syntax highlighting for code; limited free usage without an account. Lacks color support for commands (no syntax highlighting for code blocks or keywords).
+
+#### **Local Tools Setup**
+
+For local conversion, we can use **Pandoc** and **wkhtmltopdf** for more flexibility and control over the output.
+
+##### **1. Download and Install Pandoc**:
+
+- Visit the [Pandoc GitHub Releases Page](https://github.com/jgm/pandoc/releases/tag/3.5) and download the appropriate ZIP file for your operating system.
+- Unzip the file and move the contents to a folder named **Pandoc** in **C:\Program Files** (for Windows users).
+
+##### **2. Download and Install wkhtmltopdf**:
+
+- Go to the [wkhtmltopdf Download Page](https://wkhtmltopdf.org/downloads.html) and download the version suitable for your system.
+- Run the installer to set it up.
+
+##### **3. Set Up System Environment Variables**:
+
+- Right-click on **This PC** (or **My Computer**) and select **Properties**.
+- Click on **Advanced system settings**.
+- In the **System Properties** window, go to the **Environment Variables** section.
+- Under **System variables**, find the **Path** variable and click on **Edit**.
+- Add the following paths to the list (adjust if the installation paths differ):
+  - `C:\Program Files\Pandoc`
+  - `C:\Program Files\wkhtmltopdf\bin`
+
+##### **4. Convert Markdown to PDF Using Pandoc**:
+
+Once everything is set up, you can use Pandoc to convert Markdown files to PDF. Here’s the basic command:
+
+```bash
+pandoc filename.md -o filename.pdf --pdf-engine=wkhtmltopdf
+```
+
+Replace `filename.md` with your Markdown file and `filename.pdf` with the desired output name.
+
+##### **Handling Margins**:
+
+By default, Pandoc’s PDF conversion can have large margins. To adjust them, you can add options to customize the margins and page layout:
+
+```bash
+pandoc filename.md -o filename.pdf --pdf-engine=wkhtmltopdf --variable geometry:margin=1in
+```
+
+This command sets the margin to 1 inch. You can adjust the margin size as needed.
+
+You can also specify more advanced layout options like paper size, font size, and margins:
+
+```bash
+pandoc filename.md -o filename.pdf --pdf-engine=wkhtmltopdf --variable geometry:margin=1in,paper=a4 --variable fontsize=12pt
+```
+
+### **Advantages and Disadvantages**
+
+#### **Online Tools**:
+
+- **Advantages**:
+  - Easy to use, no installation required.
+  - Ideal for simple or quick conversions.
+  - Some tools like Markdown to PDF handle wide tables well.
+- **Disadvantages**:
+  - Limited functionality for larger or more complex files (e.g., wide tables, syntax highlighting).
+  - Often requires an account or has usage limits (Markdown to PDF, for example).
+  - Minimal control over margins, layout, or PDF customization.
+
+#### **Local Tools (Pandoc & wkhtmltopdf)**:
+
+- **Advantages**:
+
+  - Full control over the PDF output (margins, layout, paper size, font size).
+  - Handles complex Markdown files, large tables, and custom styles.
+  - No usage limits; ideal for frequent conversions.
+
+- **Disadvantages**:
+  - Initial setup is required (installing and configuring Pandoc, wkhtmltopdf, and environment variables).
+  - Involves command-line usage, which can be less user-friendly for beginners.

+### **Question: Complex Number Operations**
+
+**Difficulty Level:** 🟡 Intermediate  
+**Domain:** Programming (C Language)
+
+**Description:**  
+This task involves implementing operations on complex numbers using C. Complex numbers have real and imaginary parts, and common operations include addition, subtraction, multiplication, and division. The user will input two complex numbers, and the program will perform the selected operation (based on user choice). The program should also include proper input validation and error handling.
+
+**Input Example:**
+
+```c
+Enter the real and imaginary parts of the First Complex number: 3 2
+Enter the real and imaginary parts of the Second Complex number: 1 7
+```
+
+**Output Example:**
+
+```
+****Complex Number Addition****
+Result is: 4 + 9i
+
+Why did the complex number break up? It couldn't find a real solution!
+```
+
+**Instructions:**
+
+1. Implement functions for:
+   - Addition, Subtraction, Multiplication, and Division of complex numbers.
+   - A menu-driven system where the user can choose the operation to perform.
+2. The program should:
+   - Allow continuous input of complex numbers and repeat operations until the user exits.
+   - Perform proper input validation for the operation choice.
+3. Include comments and humor to make the output fun and engaging.
