Question

Match the file extensions with the appropriate file. A. txt B. \(m p 3, a u\), and wav C. gif, tiff, and jpg D. doc and wp 3 E. java, c, and cpp Program source file

Short answer

E: java, c, and cpp file extensions are for program source files.

Step-by-step solution

Understand the Question

You need to match different file extensions (A-E) with their appropriate file types. The prompt asks about a specific type, in this case, "Program source file".

Recall File Extensions

Think of the common file extensions that are associated with different types of files. For example: - Text files usually have the extension `.txt`. - Audio files often have extensions like `.mp3`, `.au`, or `.wav`. - Image files can have extensions such as `.gif`, `.tiff`, or `.jpg`. - Document files might have extensions like `.doc` or `.wp3`. - Program source files often include extensions like `.java`, `.c`, or `.cpp`.

Identify Program Source File Extensions

For program source files, the common extensions are `.java` for Java files, `.c` for C files, and `.cpp` for C++ files. These are coding or programming language files.

Match with List

Identify which of the options (A-E) includes the extensions `.java`, `.c`, or `.cpp`. Option E lists these extensions.

Verify and Conclude

Confirm that the answer makes sense by considering that the extensions from Option E are indeed used for programming source files.

Key concepts

Program Source File

When we talk about program source files, we refer to files that contain the code written in a programming language. These files are crucial for developers, as they are the very foundation of software development. Think of them as the architect's blueprint for a building.

If you are learning about these files, you will most commonly encounter file extensions like `.java`, `.c`, and `.cpp`. Each of these extensions corresponds to a specific programming language:

• `.java` is used for Java, a class-based, object-oriented language popular for web applications.
• `.c` represents C files, a versatile and foundational language often used for system software.
• `.cpp` is the extension for C++, which is an extension of C, incorporating features of object-oriented programming.

These program source files must be compiled into machine-readable code before they can be executed by a computer. The understanding of these file extensions and the languages they represent is essential for anyone venturing into the programming field.

File Types

File types indicate the kind of data contained in a file, and different file extensions help categorize these file types. This understanding is important for efficiently managing and understanding file systems and documents.

Each file extension defines the characteristics of a file and what kind of software might be needed to open it. Here are some typical file types with common extensions:

• **Text Files:** Usually end with `.txt` and contain plain text without any formatting.
• **Image Files:** Often found with extensions like `.gif`, `.tiff`, and `.jpg`, these files store image data with varying levels of compression.
• **Audio Files:** Include formats such as `.mp3`, `.au`, and `.wav` which store sound data for playback.
• **Document Files:** These might have extensions like `.doc` or `.wp3`, and they typically contain formatted text and images.

Correctly understanding file types and extensions assists with choosing the appropriate application to effectively use or edit the file. By grasping these concepts, users can seamlessly interact with digital information.

Educational Content on File Extensions

Gaining knowledge about file extensions is like learning the language of computer files. This understanding helps in effectively managing, organizing, and utilizing computer data, a valuable skill in our digital world.

Educational resources often focus on:

• **Identification of File Types:** Learning about different file extensions and what they signify helps students navigate and utilize files effectively.
• **Security Implications:** Understanding that certain file types might pose security risks helps in exercising caution with unfamiliar extensions.
• **Software Associations:** Knowing which programs are typically used to open different file types can aid in problem-solving, especially in troubleshooting scenarios.

By strengthening this knowledge, students not only enhance their technical skills but also improve their efficiency and safety while working with digital devices and software. Learning about file extensions prepares individuals for a variety of technological challenges and opportunities.
