I am trying to write a program which allows the user to move an '@' symbol around a field of dashes with the arrow keys. It works, but instead of refreshing the field when the user presses a key, it creates an entirely new field with the change. Is it feasable to simply "refresh" the data when the user makes a change? Or should I just be happy with what I have (quite new at programming)? Thanks for any and all help.
#include <iostream>
#include <conio.h>
using namespace std;

const char CPPKEYUP = 72;
const char CPPKEYLEFT = 75;
const char CPPKEYRIGHT = 77;
const char CPPKEYDOWN = 80;

int player_x = 4, player_y = 4;

////////////////////////////////
void draw_frame()
////////////////////////////////
{
    int x, y;
    char space = '-', player = '@';
    
    for (y = 0; y < 10; y++) {
         for (x = 0; x < 10; x++) {
              if (player_y == y && player_x == x) {
                   cout << player;
                   }
              else {
                   cout << space;                 
                   }                            
              }
         cout << "\n";
         }
         cout << "\n";              
}

         {

You are going to have to go to something platform specific for the console work
OR
try the NCurses API
OR
you can use something like 'system("cls");' which will get you close to what you want, but is NOT recomended as it is bad coding.
