What are common EOF uses?

Common uses of EOF (End of File) include:

1. File Reading: When reading data from a file, EOF is used to determine when to stop reading. Programs check for EOF to avoid reading beyond the end of the file.

2. Input Handling: In interactive applications, EOF can signal the end of user input. For example, in a terminal, pressing Ctrl+D (Unix/Linux) or Ctrl+Z (Windows) sends an EOF signal.

3. Loop Control: In loops that read data from files or streams, EOF is often used as a condition to terminate the loop. This prevents infinite loops when there is no more data to process.

4. Data Processing: In data processing applications, EOF helps in batch processing of data, allowing the program to know when to finalize operations or output results.

5. Network Communication: In network programming, EOF can indicate that the remote side has closed the connection, allowing the local application to clean up resources.

6. Parsing Input: When parsing structured input (like CSV or JSON), EOF helps determine when the input data has been fully consumed.

These uses help ensure that programs handle data streams and files correctly and efficiently.
