stdin is short for "standard input." When you input data into the terminal while the program is running, this is where it goes.stdout is short for "standard output." This is where all of the data that you print out of your program (via printf(), puts(), etc.) goes.
stderr is short for "standard error." This is where you should print your error messages to (via fprintf(), fputs(), etc.).

How do you run daemon process?
In Unix, with a C program you can run a quick function to do this. There is an example at:(link moved to link section)AnswerIn Solaris, you need to disconnect your program from your "terminal" ( scripts generally inherit the stdin, stdout, and stderr of your shell when you execute them ). For a shell program you can execute "nohup $program < /dev/null > /dev/null 2>&1 &". Or the shell program can redirect its own stdin, stdout, and stderr -- then you can execute "nohup $program &".
What are the files which are automatically opened when a c file is executed?
tdin, stdout, stderr (standard input,standard output,standard error).
Program for marksheet in c language?
The std::cout and std::cin streams are peculiar to the C++ standard library. They are not available in the C standard library, but are analogous to stdin and stdout which is in the C standard library.
What is standard input and output error file?
The C standard library provides stderr as the standard error file. It is an output file, much like stdout, except it cannot be redirected via the command line. By default, error messages via stderr are output to the console, the same as the undirected stdout. However, the programmer may choose to redirect stderr to a disk file or allow the user to choose a location via command line switches. Although error messages can also be output to stdout (or indeed to any output stream), it is best to keep error messages separate from the standard output stream. For instance, the user may choose to redirect standard output to a disk file or to the input stream of another program, while error messages are directed to the console.
What are java servelets?
When the internet/web was young... there was the webserver. But it didn't do much except fulfill requests for files. Mostly images and .html documents, and such. However, someone noticed that a C program has stdin, stdout and stderr streams... So they made a file extension called .cgi (Common Gateway Interface) and told the webserver that when a request was made to this .cgi file... that it shouldn't SEND a .cgi file to the requestor... instead it should RUN the file as a program, get the program's output and sent THAT output to the browser. Thus web apps were born. Browser Request -> Webserver -> Stdin -> C program... ->>> Stdout -> Webserver -> Response to user's browser. Sun Microsystems wanted to use java for web apps. So, they made tiny classes called "Servlets" (mini-Server programs) to run instead of the C programs/Perl programs everyone else was using. Servlets work like: Browser Request -> Webserver -> Java -> Stdin -> java Servlet Class.. ->>> Stdout -> Webserver -> Response to user's browser. That's pretty much is. A Java Servlet is a program that accepts data, does some processing and then spits out results that a webbrowser would understand. Hope this answers your question.

What is the function of the cin and cout statements?
cin and cout are synonymous with stdin and stdout, implementing console input and output respectively.

What is the importance of a pipe in Linux?
Pipes are useful for redirecting inputs or outputs from a program instead of using stdin or stdout. For instance, piping the output of a command to a text file.
What is putch in C programming?
It puts a character out on the stdout file, usually the screen but stdout can be redirected. An example of stdout redirection is a web server, the stdout of a cgi program issent via the network to the client computer and not the servers monitor.
What is the significance of cin and cout operators in c plus plus?
cin and cout are not operators, they are objects. cin is console input while cout is console output (explicitly idintified as std::cin and std::cout). In other words they are the C++ standard library stream objects that represent stdin and stdout respectively. The corresponding std::cerr stream represents stderr, the console error stream. std::cerr is typically directed to the screen while std::in and std::cout are also typically directed to the screen but can be redirected via the command line when executing the binary executable.
What is Cin and Cout?
The cin and cout objects are iostream objects somewhat equivalent to stdin and stdout. The equivalent of printf ("Hello World\n"); is cout << "Hello World" << endl; The equivalent of scanf ("%d", &i); is cin >> i;
Why is error used in c language?
Error is not used. You might have meant stderr or errno.
What happens when getche is used alone?
getche is a non-standard command that accepts a character from stdin and echoes it to stdout. Used alone, that's all it does. But typically you will want to store the return value (the input character) and act upon it.
