When and why should I use stdin and stdout?

Question

I know that there are many tutorials out there but I just don't seem to understand. It would be a huge help if someone could explain it. Thank you

Answer 1

stdin means standard input, stdout means standard output. So you read data from stdin (e.g. data entered by a user) and you write data to stdout (e.g. user's screen).

Answer 2

stdin stands for standard input. and stdout means standard output. Basically input by users by keyboard or other input medium is stdin. and output to any standard medium such as display is called stdout.
