What is stdin?

stdin, which stands for standard input, is a fundamental concept in computer programming that represents the input stream from which a program reads its input. It is a communication channel between a program and its user or another program. By default, stdin is connected to the keyboard, allowing users to interact with the program by entering input via the command line. However, stdin can also be redirected to read input from files or another program's output. In many programming languages, stdin is accessed through a predefined input stream object, which provides methods or functions to read and process input data. It is an essential component in creating interactive and flexible programs that respond to user input.
