Thread: stdin

i searched on the net "what are stdin stdout stderr" but i udnerstand nothing at all
so can anyone tells me what are they ? and when do we need to use them ?

I'm sorry but this is such a basic question that can easily be solved by properly searching the net for documentation that it really doesn't deserve much of an answer.

See this. If you can't understand this documentation I recommend you find some other hobby.

That's rather hasty of teaching someone new to programming, we have all reached a point where something was hard to understand but that doesn't mean we should quit it.

stdin -> standard input: this is the file handle that your process reads to get information from you
stdout -> standard output: your process writes normal information to this file handle.
stderr -> standard error: your process writes error information to this file handle.
