Dear aimdharma,

//Under c windows os

"stdin" stands for standard input
"stdout" stands for standard output
"stderr" stands for standard error

It's Function prototypes are defined in "stdio.h" headre file.
Just include it in ur code

#include <stdio.h></stdio.h>

and use it's library functions.

ex. you may be using

scanf("",);  //stdin function.    
     printf("");  //stdout function

I hope u get something

ok see u

Solution 1

stdin and stdOut aren't functions: they are streams. You hand the stream to a function in order to read from it:

char string[256];
printf( "Please enter a long string: " );
fgets ( string, 256, stdin );

or

fputs("Hello world", stdout);

Yes. But you will get problems if you try to write to it.
