a very simple question (but i don't know)
how to write a program that receive a string from keyboard and then print it out. i write a program:
main()
{
char str[80];
gets(str);
printf(str);
}
but when i compile it, the system said something like "new line is not last charicter" and sometime the system said "a3.c is up to date"
what does them mean?
thanks.

NAME
curs_addstr, addstr, addnstr, waddstr, waddnstr, mvaddstr, mvaddnstr, mvwaddstr, mvwaddnstr - add a string of characters to a curses window
and advance cursor
SYNOPSIS
cc [ flag ... ] file ... -lcurses [ library ... ]
#include <curses.h>
int addstr(char *str);
int addnstr(char *str, int n);
int waddstr(WINDOW *win, char *str);
int waddnstr(WINDOW *win, char *str, int n);
int mvaddstr(int y, int x, char *str);
int mvaddnstr(int y, int x, char *str, int n);
int mvwaddstr(WINDOW *win, int y, int x, char *str);
int mvwaddnstr(WINDOW *win, int y, int x, char *str, int n);
DESCRIPTION
All of these routines write all the characters of the null terminated character string str on the given window. It is similar to calling
waddch() once for each character in the string. The four routines with n as the last argument write at most n characters. If n is negative,
then the entire string will be added.
RETURN VALUES
All routines return the integer ERR upon failure and an integer value other than ERR upon successful completion.
