Question

I’m using Visual Studio 2010 and I’m trying move cursor when user press right-array key on keyboard:

#include "stdafx.h"
#include <iostream>
#include <conio.h> 
#include <windows.h>

using namespace std;

void gotoxy(int x, int y)
{
  static HANDLE h = NULL;  
  if(!h)
    h = GetStdHandle(STD_OUTPUT_HANDLE);
  COORD c = { x, y };  
  SetConsoleCursorPosition(h,c);
}

int main()
{
    int Keys;
    int poz_x = 1;
    int poz_y = 1;
    gotoxy(poz_x,poz_y);

    while(true)
    {   
        fflush(stdin);
        Keys = getch();
        if (Keys == 77)
                gotoxy(poz_x+1,poz_y);
    }

    cin.get();
    return 0;
}

It’s working but just once – second, third etc. pressed not working.

Answer 1

You never change poz_x, so you always end up calling

gotoxy(2,1);

in the loop.
