Stdout, short for "standard output," is a default destination for output data generated by computer programs. It typically displays information on the screen or terminal where the program is running. This allows users to see results, messages, or errors produced by the program in real-time. In many programming languages, such as Python and C, developers can use specific functions or commands to send data to Stdout. This makes it easier to debug programs and understand their behavior, as developers can quickly view the output without needing to write it to a file or another location.
