File pointeur of stdout

[Try Kret]

Hello ,

I write a program that require the users to enter their password. How to do it?
According to a book of K&R, "When a program begins execution, three stream stdin,
stdout, stderr are already open". But how to get pointers to these stream?

Faithfully yours,
Try.

stdin, stdout, and stderr *are* file pointers to the standard input,
standard output, and standard error streams. Try reading up on functions
such as getchar, fgets, etc.

But you do have to #include <stdio.h> in order to get the declarations
for them.
