Correct Answer - 1

10
:: is a Scope Resolution Operator, it is used to access the value of global variable and ::a will return the value of global declared variable.

Q3. Which is the correct answer regarding '\n' and endl?

  1. Both are same.
  2. '\n' and endl both are used to print new line but endl flushes the buffer after printing new line.
  3. '\n' and endl both are used to print new line but '\n' flushes the buffer after printing new line.
  4. '\n' used in C programming while endl used in C++ programming.

FAQs on Assignment: Input/Output - Basics of C++ - Software Development

1. What is Input/Output software development?
Ans. Input/Output software development refers to the process of creating programs that manage the input and output operations of a computer system. This includes handling data coming into the system from various sources (input) and sending data out of the system to different destinations (output).
2. Why is Input/Output software development important in computer systems?
Ans. Input/Output software development is crucial in computer systems as it enables the communication between the hardware components and the software applications. It allows users to interact with the computer system by providing input and receiving output, making it an essential part of the overall functionality of the system.
3. What are some common examples of Input/Output operations in software development?
Ans. Some common examples of Input/Output operations in software development include reading data from a file, writing data to a database, displaying information on a screen, and receiving user input from a keyboard or mouse. These operations are fundamental in creating responsive and interactive software applications.
4. How does Input/Output software development impact the performance of a computer system?
Ans. Efficient Input/Output software development can significantly impact the performance of a computer system by optimizing data transfer rates, reducing latency in input/output operations, and improving overall system responsiveness. Poorly designed Input/Output software can lead to bottlenecks and performance issues in the system.
5. What are some best practices to follow in Input/Output software development?
Ans. Some best practices in Input/Output software development include using asynchronous I/O operations to improve performance, handling errors gracefully to ensure robustness, optimizing data transfer methods for efficiency, and considering security measures to protect data during input and output operations. Following these practices can lead to the development of high-quality and reliable software systems.
