Simple Snake Game

Snake Game is actually a mini project for first semester students .It is console application without graphic library that's why it is more interesting.This game is perfect without any error and better user interface.It is complied in c++ language.Here goes a source code you can copy and compile it . I hope it will be helpful.

Source code:

Here is the source Code of C++ Program to make a Simple Snake Game.

#include <iostream>
#include <conio.h>
#include <windows.h>
using namespace std;
bool gameOver;
const int width = 20;
const int height = 20;
int x, y, fruitX, fruitY, score;
int tailX[100], tailY[100];
int nTail;
enum eDirecton { STOP = 0, LEFT, RIGHT, UP, DOWN};
eDirecton dir;
void Setup()
{
gameOver = false;
dir = STOP;
x = width / 2;
y = height / 2;
fruitX = rand() % width;
fruitY = rand() % height;
score = 0;
}
void Draw()
{
system("cls"); //system("clear");
for (int i = 0; i < width+2; i++)
cout << "#";
cout << endl;

for (int i = 0; i < height; i++)
{

}
int main()
