C-language Receive direction key instruction allows the output on the screen to move

First, you need to know the console coordinates

#include <stdio.h>#include<stdlib.h>#include<conio.h>Main () {intx=0, y=0, I; CharKey//Accept InputPutchar ('O');//a Little Dot     while(1) {Key=getch ();//accept input without echo    if(key=='Q') Break;//input WASD, enter Q to exit    Switch(key) {//Set any hotkey//Case ' W ': (x>0?--x:x);//Case ' s ': x++;break;//Case ' a ': (y>0--y:y);//Case ' d ': ++y;break;//Default:break;//////////Set any hotkey     Case- +: Key=Getch (); Switch(key) { Case  the: (x>0?--x:x); Break;  Case  the: x++; Break;  Case  the: (Y>0? --Y:Y); Break;  Case  the:             ++y; Break; default: Break; }            default: Break; } System ("CLS");//Clear Screen     for(i=0; i<x;i++) printf ("\ n");  for(i=0; i<y;i++) printf (" "); Putchar ('O');//Output}}
