scanf equivalent with arrow key support in c - c

Question

Is there some functions in c which behaves like scanf (taking inputs from the keyboard) while being able to move the cursor in the input by pressing the arrow keys, like in a terminal ?

Answer 1

There are no function in C standard to do that.
You can look at ncurses

Answer 2

In addition to previous suggestions, if you want to do a little work you can "roll your own" using the vt100 escape sequences, which most (probably all) terminal programs continue to support. Here's a small sample program,
#include <stdio.h>
#include <string.h>
#include "vt100.h"
int main ( int argc, char *argv[] )
{
char cupstr[99];
char reply[99];
strcpy(cupstr,_cup(12,25));
printf("%sEnter Data ---> ",cupstr);
fgets(reply,88,stdin);
strcpy(cupstr,_cup(13,25));
printf("%sEchoed Data --> %s\n",cupstr,reply);
}
And the big part is that vt100.h containing all the escape sequences,

These escape sequences let you program all the stuff that used to look so cool on vt100's, vt220's, etc, a long, long time ago (but right here in this galaxy).
