## Step-by-Step Instructions

### Implement Conditional Logic in Cava

**Navigation**: Console > OpenSearch > Code Execution > Cava Editor

1. Log in to the OpenSearch management console.
   - Element: **Username** (text_input) — login page
   - Element: **Password** (text_input) — login page
   - Element: **Log In** (button) — bottom of login form

2. In the left navigation panel, click **OpenSearch**.
   - Element: **OpenSearch** (link) — left sidebar menu

3. Under the OpenSearch section, select **Code Execution**.
   - Element: **Code Execution** (link) — submenu under OpenSearch

4. On the Code Execution page, click **Cava Editor** to open the coding interface.
   - Element: **Cava Editor** (button) — main content area
   - Notes: A new editor panel loads with a default template

5. In the code editor, replace the sample code with your conditional logic using one of the supported branch structures:
   - `if (Boolean expression) { ... }`
   - `if (Boolean expression) { ... } else { ... }`
   - `if (Boolean expression) { ... } else if (Boolean expression) { ... } else { ... }`
   - Element: **Code Editor** (textarea) — center of the page
   - Notes: Switch statements are not supported in Cava

6. Click **Validate Code** to check syntax before execution.
   - Element: **Validate Code** (button) — top-right corner of editor panel
   - Notes: Errors will appear in the output log below the editor

7. If validation passes, click **Run** to execute the Cava code.
   - Element: **Run** (button) — next to Validate Code
   - Notes: Execution results appear in the **Output** panel below the editor

8. Review the output in the log window.
   - Element: **Output** (panel) — bottom section of the page
   - Notes: The return value of the `main()` function is displayed here

**Form Fields**: None

## FAQ

Q: Where can I write and test Cava code with conditional logic?
A: Use the Cava Editor under Console > OpenSearch > Code Execution. This interface supports full editing, validation, and execution of Cava programs.

Q: Are switch statements supported in Cava for conditional branching?
A: No. Cava only supports `if`, `if...else`, and `if...else if...else` branch structures. Switch statements are not available.

Q: Do I need to define a main() function in my Cava code?
A: Yes. All executable Cava code must include a `static int main()` function that returns an integer, as shown in the examples.

Q: Can I modify and re-run my code multiple times in the same session?
A: Yes. You can edit the code in the editor, click **Validate Code** again, and then **Run** as many times as needed without leaving the page.

Q: What happens if my Boolean expression uses undefined variables?
A: The **Validate Code** step will fail with a compilation error indicating the undefined variable. Ensure all variables are declared before use.
