C language console read up and DOWN ARROW key instructions

First, you can detect any keystroke key value

#include <stdio.h>#include<conio.h>int  main () {           char  ch;      while ((Ch=getch ())! =0x1B/**/{   printf ("% d \ n"

is the key value of the next key or lower.

Second, the console reads the direction key directive

Method One

//capturing key Values#include <stdio.h>#include<conio.h>intMain () {intch;  while((Ch=getch ())! =0x1B)/*Press ESC to quit ...*/   {      Switch(CH) { Case 0xE0:         Switch(ch=Getch ()) {             Case  the: printf ("up\n"); Break;  Case  the: printf ("down\n"); Break;  Case  the: printf ("left\n"); Break;  Case  the: printf ("right\n"); Break; default:                Break; }          Break; default:          Break; }   }}

Method Two

#include <stdio.h>#include<stdlib.h>#include<conio.h>#include<windows.h>intMain () {Charkey;  while(1)    {        //int t=1;key=Getch (); Switch(key) { Case- +: Key=Getch (); Switch(key) { Case  the: printf ("up\n"); Break;  Case  the: printf ("down\n"); Break;  Case  the: printf ("left\n"); Break;  Case  the: printf ("right\n"); Break;  Case-123: printf ("f11\n"); Break;  Case-122: printf ("f12\n"); Break; default:            //printf ("%x,%d,%c\n", t,t,t);printf"NULL"); Break; }             Break; default:            //printf ("%x,%d,%c\n", t,t,t);printf"NULL"); Break; }    }    return 0;}
