If You have some ideas for practicing tell me :)

There are some bugs.
I will fix it as soon as possible.

Here is the code:

#include <iostream>
#include <conio.h>
#include <windows.h>
#include <concrt.h>
using namespace std;
bool gameover;
const int height = 20;
const int width = 20;
int x, y, fx, fy, score;
int tailx[100], taily[100];
int tail;
enum eDirecton { STOP = 0, LEFT, RIGHT, UP, DOWN };
eDirecton dir;
void setup()
{
    gameover = false;
    x = width / 2;
    y = height / 2;
    fx = rand() % width;
    fy = rand() % height;
    score = 0;

}
void draw()
{
    system("cls");
    for (int i = 0; i < width+2; i++)
        cout << "-";
    cout << endl;

    for (int i = 0; i < height; i++)
    {
        for (int j = 0; j < width; j++)
        {
            if (j == 0)
                cout << "|";
            if (i==y&&j == x)
                cout << "O";
            else if (i == fy&&j == fx)
