Identifying Standard Input/Output Streams

1. Understanding Standard I/O Streams
   Standard Input/Output (I/O) streams are predefined channels used for input and output operations in programming. These streams facilitate interaction between the program and the user or other devices.

2. Identifying Each Option

   • stdin: This stands for standard input. It is the default input stream; typically, it reads input from the keyboard.
   • stdout: This stands for standard output. It is the default output stream; usually, it sends output to the terminal or console.
   • stderr: This stands for standard error. It is the default stream for outputting error messages or diagnostics and is also typically directed to the terminal.

3. Final Determination
   All three options listed—stdin, stdout, and stderr—are standard I/O streams.

Final Answer

The standard input/output (I/O) streams are: stdin, stdout, and stderr.
