How does exception handling contribute to a program's robustness?
- Enhances code reliability by handling unexpected errors gracefully
- Increases code complexity and performance issues
- Only applicable in certain programming languages
- Reduces the need for testing
Exception handling improves a program's robustness by allowing it to gracefully handle unexpected errors. It prevents abrupt termination and provides mechanisms to recover or log errors, contributing to overall code reliability.
When integrating a third-party library in CodeIgniter, it is usually placed in which directory?
- application/libraries
- application/third_party
- system/libraries
- system/third_party
When integrating a third-party library in CodeIgniter, it is usually placed in the "application/third_party" directory. This directory serves as a designated location for external libraries that are not part of the CodeIgniter core. Organizing third-party libraries in this directory helps maintain a clean and structured project layout.
During a system upgrade, a developer uses ________ in CodeIgniter to ensure database compatibility with new features.
- controllers
- migrations
- models
- seeds
In CodeIgniter, migrations are used to version control the database schema. During a system upgrade, a developer can create and run migrations to modify the database structure, ensuring compatibility with new features.
In CodeIgniter, the ________ method allows controllers to handle multiple HTTP verbs in a single method.
- _remap
- handleHTTP
- multiHTTP
- requestMethod

How does the Email Class handle attachments in an email?
- Attachments are automatically added if the email body contains file paths.
- Attachments are handled by specifying file paths directly in the to() method.
- Attachments are handled using the attach() method, which attaches files to the email.
- The Email Class doesn't support attachments.
The Email Class in CodeIgniter handles attachments using the attach() method, allowing you to include files in your emails. This method allows you to specify the file path and other relevant details.
In a multi-threaded application, an exception in one thread should be handled in a way that ________.
- Does not affect other threads
- Pauses all threads until resolved
- Prompts the user for a resolution
- Terminates the entire application
Handling an exception in a way that does not affect other threads is essential in a multi-threaded application. Pausing or terminating the entire application is generally not recommended as it could disrupt other threads and impact the overall application stability.
Database ________ is a process of inserting initial data into the database for testing purposes.
- Insertion
- Populating
- Seeding
- Seeding:insert
Database Seeding is the process of inserting initial data into the database for testing purposes. It helps to populate the database with dummy data for testing and development.
