In CodeIgniter, which directory is designated for storing view files?
- application/views
- code/views
- content/views
- system/views
In CodeIgniter, the application/views directory is designated for storing view files. Views are responsible for presenting the data to the user. This separation helps in maintaining a clean structure and follows the MVC pattern where views handle the presentation logic.
How does seeding differ from normal data entry in a database?
- Normal data entry involves entering data through user interfaces
- Seeding and normal data entry are the same
- Seeding is only used for populating tables with empty records
- Seeding is the process of adding initial data to the database for testing purposes
Seeding in CodeIgniter refers to the process of adding initial data to the database, typically for testing and development. It is different from normal data entry, which involves inserting data through user interfaces or forms during regular usage of the application.
The function $this->load->view('view_name', $data); in CodeIgniter is used to load a view and pass ________ to it.
- Data
- Libraries
- Models
- Styles
The function $this->load->view('view_name', $data); in CodeIgniter is used to load a view and pass data to it. The data variable is an associative array containing information that needs to be displayed in the view.
Which method in the Email Class is used to send HTML formatted emails?
- send()
- set_format()
- set_html()
- set_mailtype()
The set_mailtype() method in the Email Class is used to specify the email format. Setting it to 'html' enables the sending of HTML-formatted emails. This is essential when you want to include styled content in your emails.
What is the primary goal of SQL injection attacks?
- Code execution
- Data manipulation
- Server overload
- Unauthorized access to a database
SQL injection attacks aim to gain unauthorized access to a database by exploiting vulnerabilities in the input handling of SQL queries. Attackers try to manipulate or extract sensitive data by injecting malicious SQL code.
A security audit requires tracking unauthorized access attempts in a CodeIgniter application. This can be done by analyzing the ________.
- Access Logs
- CSRF Token Usage
- Error Logs
- Session Data
Analyzing the Access Logs is crucial for tracking unauthorized access attempts during a security audit. Access Logs provide information about requests made to the application, helping identify potential security threats.
What is the primary purpose of error handling in CodeIgniter?
- Displaying errors to the user
- Handling errors gracefully
- Ignoring errors completely
- Logging errors for analysis
Error handling in CodeIgniter is primarily about dealing with errors in a way that doesn't disrupt the user experience. This involves handling errors gracefully to provide useful information without revealing sensitive details.
How does radix sort differ from comparison-based sorting algorithms like bubble sort and merge sort?
- Radix sort is less efficient than bubble sort
- Radix sort only works with integers
- Radix sort uses comparison operations
- Radix sort uses the actual values of the elements
Radix sort differs from comparison-based sorting algorithms by considering the actual values of the elements rather than relying on comparisons. It operates based on the structure of the keys rather than their values.
What is the time complexity of BFS when implemented on an adjacency list representation of a graph?
- O(E)
- O(V * E)
- O(V + E)
- O(V)
The time complexity of BFS on an adjacency list representation of a graph is O(V + E), where V is the number of vertices and E is the number of edges. BFS visits each vertex and edge once, making it a linear-time algorithm with respect to the size of the graph.
What are the main applications of Dijkstra's algorithm in real-world scenarios?
- Shortest path in network routing
- Image processing
- Load balancing in distributed systems
- Genetic algorithms
Dijkstra's algorithm is widely used in network routing to find the shortest path. It's applied in scenarios like computer networks, transportation systems, and logistics for efficient pathfinding. Other options, such as image processing or genetic algorithms, are not primary applications of Dijkstra's algorithm.
